The History of Birth Control and Eugenics

4821 views

I’m a 30-year-old woman in a long-term relationship. If I had a dollar for every time someone made the comment, “If you wait until you’re ready to have a baby, you’ll never have one,” I could retire. This statement is an oxymoron to our behavior as a species, because we have been trying to control family planning as early as 1550 B.C. The first known contraception attempt was found in an Egyptian manuscript called the Ebers Papyrus. It directs women on how to mix dates, acacia and honey into a paste, smear it over wool and use it as a pessary, a medical device inserted into the vagina and held in place by the pelvic floor musculature, to prevent conception.

Today, hormonal contraception is used by 98 percent of women at some point in their lifetimes. Politicians and religious leaders still battle the rights and responsibilities of family planning in 2012. Even more controversial than the current reproductive legislation is the history of the little pill that changed the world. I don’t want children (if I ever find myself at the doors of motherhood it will be purely by accident), I can’t take hormonal birth control, and I think the battles over birth controls and abortions are simply ridiculous (it’s 2012 and this is what we have to fight in the ‘modern’ world?); however, as a woman it is important to understand the history of how modern birth control was conceived.

Contraception

From the Egyptians, contraception evolved from sheep-bladder condoms, to lemons cut in half and used as a cervical cap, to chastity belts, to the various products we have today. In a previous article, I wrote about the various hormonal and non-hormonal birth controls for men on the market or in the research phase. But, more than the interesting inventions for contraception worldwide (check out Time Magazine’s timeline of birth control here), I’d like to look specifically at the long battle for birth control in America.

Comstock Act

As a libertarian, I believe that society could run more efficiently without many of the ridiculous laws that pass through legislation. History and current legislation show that our politicians and leaders think the opposite. In 1873, in an attempt to regulate morality in this country, the Comstock Act was passed. The “Act for the Suppression of Trade in, and Circulation of, Obscene Literature and Articles for Immoral Use,” banned everything from obscene literature, to birth control and abortion devices. Doctors could not even pass on information about sexually transmitted diseases.

Margaret Sanger

Margaret Sanger was a nurse who saw women suffer and die from unwanted pregnancies. Her own mother had 18 pregnancies, 11 children and died at the age of 40. Sanger worked in New York’s Lower East Side with immigrant and lower class women who often died from complications from unwanted pregnancies and illegal abortions. She opened up the first birth control clinic in 1916 passing out diaphragms, condoms and literature on STD’s and birth control. Nine days later she was arrested and charged under the Comstock Laws. Sanger appealed the conviction, but lost; however, the New York appellate court gave doctors the right to hand out contraceptive information, if prescribed for medical reasons. In 1921, she founded the American Birth Control League, which later became Planned Parenthood. These two organizations later merged and became what we now know as Planned Parenthood.

In 1936, Sanger helped bring the case of United States v. One Package to the U.S. Circuit Court of Appeals which allowed physicians to legally mail birth control devices and information throughout the country. Yet, it wasn’t until 1965, in the Supreme Court case of Griswold v. Connecticut, that the private use of contraceptives was deemed a constitutional right.

In her lifetime Sanger published various magazines and pamphlets about birth control. She traveled through Europe and Asia promoting and helping develop spermicidal jellies, foam, powders and hormonal contraceptives. It wasn’t until 1950 that the first oral contraceptive, AKA the pill, was developed.

Birth Control and Eugenics

Sir Francis Galton, the cousin and disciple of Charles Darwin, is the father of the applied science of eugenics. One the goals of eugenics was to encourage people of above average intelligence and physical capabilities to breed in order to make an improved human race. The offshoot was racism, classism and discrimination against physically/mentally handicapped.

An often hidden and/or denied history of Margaret Sanger is her beliefs and practice of eugenics. Prior to Hitler’s attempt to create a ‘master race’ there was a strong eugenics movement in America. As many as fifteen states had eugenics laws on the books by 1924, but Virginia was the only state to rigidly enforce the marriage laws prohibiting interracial marriages with the Racial Integrity Act of 1924. Also popular amongst the eugenics movement was forced sterilization. By 1956, twenty-four states had laws providing for involuntary sterilization on their books. These states collectively reported having forcibly sterilized 59,000 people over the preceding 50 years.

How does this tie into birth control and Margaret Sanger? In a lot of her writing she refers to the Eugenics movement. In one of the issues of Birth Control Review she writes, “Birth Control is not merely of eugenic value, but is practically identical in ideal with the aims of Eugenics.” (The article titled “The Eugenic Value of Birth Control Propaganda” can be viewed here). She did not deny or hide her ties to eugenics practices, yet history often overlooks this fact. Even Planned Parenthood glosses over the issue and simply states, “Her views on eugenics and racial issues remain a subject of bitter debate to this day.”

While birth control has allowed women and men to have control over their reproduction rights and responsibilities, and Margaret Sanger has opened many doors for women, it is important to understand the history of why it was developed. An often overlooked piece of American History is that Hitler actually took his ideas for genocide and creating a master race from the American Eugenics movement. A majority of the states had sterilization and marriage laws that weren’t overturned until the 1950’s and 60’s. Don’t get me wrong, I’m ecstatic that we have condoms, birth control pills, and other forms of protection from unplanned pregnancies and STDs. I’m also glad that we have the right to these medications, devices, and basic information without a ridiculous law on morality, but with our ability to genetically modify children, I wonder how long it will be until a new and modern eugenics movement starts to develop; especially since we often overlook this snippet of American history.

Why Men Should Care About Women’s Health

2504 views

To All the Men –

Over the past twenty to thirty years our medical and technological understanding has grown by leaps and bounds. From barely grasping the full effect of various hormones and chemicals in the brain to mapping the hormonal origin of the ability to nurture. We’ve made amazing strides and among these strides has been women’s health and medicine.

Just a few decades ago many men concluded their interest into women’s health with the attitude that we’ll just never understand a woman.

For centuries we have held her body as a mystery. For romanticism that serves a beautiful purpose, but in reality it creates far more problems for the women to which we adorn with such awe. Many times I have heard of gruesome historical stories relating to what some called modern medicine and others called butchery. Back then, by their standards, that was on some low level acceptable. Today it is not. The good news is that modern medicine and technology has brought us a long way to care for our women far better than our forefathers ever could. As a man I try to think forward to the possibility of having a daughter of my own. Part of my role in providing security for her is growing in my understanding of her health.

As men, it should be one of our chief concerns to obtain a significant and ever expanding knowledge base of women and their health as they are our sisters, mothers, wives, and most importantly, our daughters. Today there has been more progress in breast cancer and various areas of illnesses afflicting women than in any time in the history of our species. It is worth mentioning because it has resulted from a multitude of men and women and their tireless effort.

Oxytocin

With advances in medicine and our understanding of women’s health, we now understand a large part of what naturally makes a woman Mother Nature’s chosen nurturer. We understand the “bonding hormone” called oxytocin. Oxytocin is a hormone that both men and women produce but is produced much more in women during their younger years than in men. This is the hormone responsible for giving a woman the want and need to build incredibly strong and long lasting intimate bonds with their babies and spouses.

A wonderful example of the oxytocin difference in men and women is demonstrated in sex; immediately after sex a woman’s level of oxytocin increases far higher than her partner. There is a longing to be close afterwards and this closeness makes her feel a stronger and more intimate bond beyond just the act of sex. This hormone is also increased after childbirth causing women to have an incredibly strong bond with their newborn. With men it’s almost the complete opposite. We create the same hormone but in much smaller quantities in our younger years. As we age our levels of oxytocin increase making us want closer relationships and bonds with our children, grandchildren, and spouses.

Oxytocin is only a small aspect of women’s health but the reason I point it out is, thirty years ago it was virtually unknown. Other illnesses like breast cancer take center stage and we have thrived to provide an incredible amount of research and options so that breast cancer is an illness that claims fewer lives year after year. Today it is a fight that our women (and a small amount of men) can win.

This is Just the Beginning

There is still much research needed. With research into oxytocin maybe we can understand abnormalities that may result from a low level of this hormone. When a woman suffers emotional trauma, does this hormone become deficient? If so, it would explain why some women who survive emotionally and physically traumatic events struggle to create that bond with their husbands and sometimes their children. Do rape victims produce less oxytocin? If so, how do we help them? What is a normal level and how do we fix this problem. These are just a few of the questions we need to find answers to. New doors that once opened will lead to better lives, relationships, treatments, and medical procedures for women.

As a man, I can’t speak as a woman would about women’s health; however I can speak as a man should. It is our duty as men to help care for and help provide security for our women. To help strengthen them so that they can live out their lives in the most meaningful way they choose. To support them and help them find answers to the problems that plagues them. In doing so we enrich our future and we do our part to better understand what we cherish the most – our women.

Summertime Migraine Survival

2035 views

Living with Migraine disease can be emotionally and physically exhausting. Getting Migraines during the summer can be especially draining because this is typically a time when families take vacations, relax and have fun. Summer is time for pools, picnics and party’s; three things that can trigger a Migraine attack in a snap. So here are some survival skills to help with the three big summer “P’s”

Spending time by a pool can be very problematic for many Migraineurs.  As we cover ourselves up with sunscreen, wear lightweight protective clothing and put hats our heads, our eyes need to be shielded too. When we sit around a pool, care needs to be taken with our eyes, because the sun may not be the only Migraine trigger.  Any glare that may reflect from the pools surface and from other objects around the pool can also be problematic.  Wearing good sunglasses is a must when around any pool. The Center for Disease Control recommends (however untrendy they may be) wearing wraparound sunglasses with as much UVA and UVB ray protection as you can buy. This type of protective sunglasses may also help reduce the risk of cataracts and protect the fragile skin around our eyes.  Shade may be the only option for some people with lupus, MS and other chronic diseases. Being prepared is important when managing these conditions, so packing a big beach umbrella, or cabana in case you are unable to find shade, is a good idea. Moderation here is important too.

If you plan a picnic this summer, whether a family outing or romantic rendezvous, here are a few things to consideration before you go:

  1. Plan your event for the time of the day that is “normally” good for you. Maybe a lunch time picnic would be better than a dinner one, or vice versa.
  2. Pack items that are trigger “safe” foods – ones you currently know won’t trigger a Migraine.
  3. If it’s a family affair, have your family members help plan the foods they want to eat.
  4. Picking your picnic location is important too. With a little effort, you will be able to find a spot that has both a quiet peaceful area for you and some fun for the family.
  5. When invited to a picnic, pre-planning is essential. Eating a light trigger free snack (if you are unsure of the menu) is not a bad idea. If you don’t think there will be anything for you to eat so you won’t trigger a Migraine, bring you own and have fun!
  6. Make sure you have enough water to stay hydrated  – bring along an extra bottle if need be.

Summer parties are fun, but not when you have a Migraine. To ensure you make the most of you party try maintaining a regular sleep schedule, especially on weekends. Sleep plays a vital role in our Migraine management plan. Consider these things when trying to maintain your sleeping schedule:

  1. Keep the time you go to bed and time you wake the same each day.
  2. Make sure your bedroom is restful and relaxing; a place you want to sleep not read or watch TV.
  3. Try to limit any drinks a couple hours before bedtime.
  4. Eat your last meal four hours before you go to bed.
  5. Try to stop napping  during the day – if you must – only take a 30 minute nap before 3 pm.
  6. Use visualization and relaxation techniques to aid with sleep.

There you have it. These simple, easy to do “survival” tips may help us have a better, less Migraine-filled summer. Don’t forget about keeping a Migraine diary too!

Birth Control – Reflected in the Numbers

1762 views

The National Center for Health Statistics recently published a report that found pregnancy rates in the United States have declined since 1990, with the exception of women in their 30s and 40s.

The data was compiled between 1990 and 2008 and analyzed by The National Center for Health Statistics, which allowed the agency to observe trends over the past two decades. What they found was a decline in pregnancies, an overall reduction in abortions, and fewer live births.

Pregnancy rates for black and hispanic teenagers are still two to three times the pregnancy rate of white teens, but there has been an overall drop in the number of pregnancies for black and hispanic teens. In fact, the number of teenage pregnancies in 2008 was 40% lower than the number of teenage pregnancies in 1990 – and the teenage pregnancy rate has not been so low since 1976.

In addition, the number of abortions among teenagers declined 56%, with fewer abortions among all age groups. These statistics suggest there have been fewer unwanted or unplanned pregnancies.

Though the highest pregnancy rate was among women between the ages of 25 and 29, there has still been a decline in the number of pregnancies for this age group (albeit slight), with the only increase in pregnancy rates among women in their 30s and early 40s.

The data hints at an increased use, or more effective form, of birth control, which would allow more women to better plan their pregnancies. The rise in pregnancies among 30- and 40-year-old women may reflect an increase in the number of women that want to start a family after establishing their careers.

Decreased pregnancy rates may not be a result of birth control methods alone; a combination of other factors, such as further education, increased accessibility to information (the Internet), and the economy, may have played a part in the pregnancy decline as well.

Even so, birth control has empowered women in the United States by giving us the ability to choose when and if we want to start a family and how big that family will be. With more freedom (whether it’s due to having no children or just fewer mouths to feed), women can focus on their education, pursue career paths, and live adventurously. Of course, birth control methods could still use some improvement.

Can Sexual Arousal Be Bought?

1985 views

A number of women are looking to over-the-counter remedies for increased sexual desire, arousal, and satisfaction, according The New York Times.

No FDA Approved Medication for Female Sexual Arousal

Though the FDA has approved sexual enhancement drugs for men, such as Viagra, there are no such drugs available for women. In 2010, the FDA denied approval for flibanserin, a drug that purportedly increased sexual arousal in women.

The denial may have been because the increase in sexual desire among the women taking flibanserin did not far exceed the increase in sexual desire among the women taking the placebo. It may have also been due to the fact that the positive effects of the drug did not outweigh its adverse effects, such as dizziness, nausea, fatigue, and insomnia.

A low-dose testosterone patch, which was intended to increase arousal and desire in women who had hysterectomies was also denied in 2004. Now, we are awaiting the approval ofFemprox, a topical drug that is intended to increase female libido.

At this time, there is no medication available for female sexual arousal disorder, which is also referred to as Hypoactive Sexual Desire Disorder (HSDD), a form of female sexual dysfunction.

Women Turn to Over-The-Counter Options

Naturally, a woman concerned about decreased sexual desire will turn to other options: Lubricants, arousal gels, massage oils, vibrators, and herbal supplements are just some of the products marketed to get your blood pumping.

When a product claims to increase a woman’s sexual arousal and satisfaction, she may just give it a shot herself, even if such claims have not been backed by a reliable source.

Consider the Options

The problem is that these over-the-counter products are unregulated, which means they do not require testing prior to public consumption. Just as toxins in cosmetics can be absorbed by the skin, chemicals in lubricants and gels can be absorbed by the skin, too.

Though doctors seem to approve of the products, it may be ideal to first consider other factors that may contribute to any decrease in sexual arousal. A drop in libido may be the result of stress, which is most likely impacting a number of women in the US. In addition to stress, relationship problems or a lack of intimacy may also impact a woman’s level of sexual desire and her ability to be aroused.

If your relationship is in good standing and you find that you are usually in a relaxed state of mind, then a low libido may be due to prescribed medications, such as antidepressants and birth control pills. Dr. Irwin Goldstein, the Director of San Diego Sexual Medicine at Alvarado Hospital, suggests determining the underlying issue for using sexual enhancement products. Hormonal imbalances from birth control pills may be the main reason for changes in sexual stimulation, and the libido fix may be as easy as changing birth control methods.

Mayo Clinic reminds us that communication is important to improving sexual satisfaction, whether there are relationship issues that need to be sussed out, or hormonal imbalances that should be discussed with the gynecologist.

If you decide to use over-the-counter stimulants, try to focus on the enjoyable aspects of sex, rather than why you bought the product. The New York Times reported that some experts are concerned that these products may cause women to focus on areas that need improvement, only putting pressure on women to perform – and we all know how difficult it is to perform under pressure.

Male Birth Control – Myth or Available Science?

2616 views

I’ve never been able to take hormonal birth control. I have tried and the side effects were so extreme that I almost ended up in the ER more than once. After telling each new doctor my past horror stories, they would each reassure me that I simply had the wrong doses and had to try a different brand. I tried three times in my adult life and every single time was a disaster that seemed to progress from the last. So, I gave up on hormonal birth control.

Most women I know have been on birth control most of their adult life, some even since they were teenagers. While I always tell myself that there might be long-term side effects outside of the ‘clinical trial’ time frames (not that I wish bad health on anyone, but would be my top concern if I was on any medication long term), most women are happy poppin the pill (or now the other various forms of hormonal birth control like IUD, rings, patches, etc). Furthermore, most men are happy letting their lady take on that responsibility.

For the most part, I’m okay not being on a hormonal birth control. It is awkward when dating someone and getting to that point where things might lead to more than just dinner a movie and I have to bring up that little, unpleasant fact, but otherwise I’m happy with my natural mood swings and erratic hormones.

I’ve been with my boyfriend for over 3 years now, so I haven’t had to have “the talk” recently. However, back in my dating days, I was always shocked at how shocked men were that I wasn’t on the pill. It was like the idea of a woman not being on some form of birth control was absurd to them. What I love about Brent (well, I love a lot of things about him) is that after witnessing the extreme effects of hormonal birth control in my body first hand, he has accepted that we have to take other measures to prevent pregnancy. He’s also assured me that if a male birth control comes available he would be willing to try, but only after many clinical trials and a year or two of being on the market (I can’t blame him with the controversial drugs the FDA has approved in the past).

Male Birth Control

Turns out there are forms of male birth control. Quite a few actually and very few of them are hormonal, which would have the most risk and side effects. Some sound weird, and lots are still in clinical trials (And there is no way in hell we would even consider a clinical trial – can you imagine being in the placebo group?!). Let’s look at some of the new forms of birth control that share the reproductive responsibility.

It is important to remember that, like female contraceptives, these treatments do NOT protect against sexually transmitted diseases.

RISUG

In India, they have developed a long-term, reversible solution that is 100% effective in clinical trials. The Reversible Inhibition of Sperm Under Guidance or RISUG might be a good option if your man doesn’t mind needles. According to Techcitement the simple procedure is as follows: “A doctor applies some local anesthetic, makes a small pinhole in the base of the scrotum, reaches in with a pair of very thin forceps, and pulls out the small white vas deferens tube. Then, the doctor injects the polymer gel (called Vasalgel here in the US), pushes the vas deferens back inside, repeats the process for the other vas deferens, puts a Band-Aid over the small hole, and the man is on his way. If this all sounds incredibly simple and inexpensive, that’s because it is.” How does it work? “The two common chemicals – styrene maleic anhydride and dimethyl sulfoxide – form a polymer that thickens over the next 72 hours, much like a pliable epoxy, but the purpose of these chemicals isn’t to harden and block the vas deferens. Instead, the polymer lines the wall of the vas deferens and allows sperm to flow freely down the middle (this prevents any pressure buildup), and because of the polymer’s pattern of negative/positive polarization, the sperm are torn apart through the polyelectrolytic effect.” Another benefit, RISUG does not cause the common side effects of a vasectomy: granulomas and an autoimmune response.

Will it be approved? It has yet to get approval in India, and, according to Science Based Medicine, trials on rabbits are just starting in the US (published May 2012). Perhaps this birth control is just too good to be true and pharmaceutical companies stand to loose too much if men have to get a shot once every ten years and without side effects, are 100% reversibly infertile.

What’s more – this treatment might actually prevent HIV transmission from male to female during intercourse.

Male Hormonal Birth Control

In Denmark, studies are being conducted in hormonal birth controls that rather than taking a pill daily (because men can’t bother with that?), tiny rods are inserted under the skin of the arm that deliver the hormones. These rods deliver etongestral, a progesterone often used in female birth control pills. The etongestral blocks sperm production and is considered reversible. The downside: to block sperm production, it blocks testosterone production as well. Participants of the study have to get testosterone replacement therapy injections every 4-6 weeks to maintain their sex drive, as well as their male characteristics. If approved, patients would only have to change the rods every three years.

There are other hormonal birth controls on trial. Some involve topically applied gels, others pills, or shots every few months; but they all work the same and have the same side effect of blocking testosterone production in the testes.

Other Odd ‘n’ Ends

There are surprisingly lots of clinical trials and products out there for male birth control. And maybe not-so-surprisingly, those that were not hormonal had very few side effects. I suppose it makes sense that it would be easier to control men’s sperm that are located externally, opposed to internally manipulating our eggs.

Suspensories, a pair of brief-like garments holds the testes closer to the body, raising the temperature of the testes and suppressing sperm count and making the remaining sperm poor swimmers. Here are other heat treatments.

Intra Vas Device (IVD), is a set of implants that block the flow of sperm. According to malecontraceptives.org, “These tiny, pre-formed, flexible silicone plugs are inserted into the vasa deferentia, the tubes carrying sperm from the testes. The device is sized to the width of each recipient’s vas deferens, filling the lumen (the opening in the vas tube) but not stretching the tube. Two plugs are inserted in the same vas with a small space between them. If sperm pass around the first plug and enter the space between the two plugs, the second plug blocks them. In order to prevent the plugs from moving within the vas deferens, they are anchored with small sutures to the wall of the vas deferens itself. Once implanted, they can not be felt. The IVD is similar in function to a vasectomy, but it leaves the vasa deferentia intact.”

Hopefully these new forms of birth control will soon be on the market and women like me, who can’t or choose not to, take hormonal birth control will be able to share the responsibilities of reproduction. All I can say is it’s about damn time!

Hair Relaxers Tied to Uterine Tumors

2157 views

A number of black women in America are turning away from the chemicals that relax and straighten their hair, which the New York Times referred to as a movement “characterized by self-discovery and health.” Now, more black women are embracing their natural hair as a part of who they are, a movement that may have a bigger impact on their health than many realize.

Studies suggest that the chemicals in hair relaxers may possibly be “endocrine disruptors,” or chemicals that disrupt the endocrine system, which regulates our hormones. The Slone Epidemiology Center of Boston University published research in the American Journal of Epidemiology, indicating a possible link between the use of hair relaxers and uterine leiomyomata, or benign tumors in the uterus.

The skin is the human body’s largest organ and is capable of absorbing chemicals into the body, which is why many turn to natural cosmetic options. It is possible that the chemicals in hair relaxers are absorbed into the scalp, or introduced into the body via scalp lesions or chemical burns. An increased incidence of uterine leiomyomata was observed in women that were either exposed to the chemicals for longer periods of time or in women who had more burns. The scientists also observed that the frequent use of hair relaxers increased the risk of uterine leiomyomata.

It is possible that hormonal disruption may be due to a woman’s weight, her percentage of fat tissue, and/or the use of other products. Though this study is limited and does not confirm that hair relaxers cause uterine leiomyomata, it is important to be aware of health implications associated with hair relaxers, just as we should be aware of how other cosmetic products can affect our health. Embracing our natural beauty is the first step towards improving our overall well-being and health.

Female Divers and Decompression Illness (DCI)

2197 views

I just finished a two-week research dive program at the Scripps Institute of Oceanography, which happened to be poorly timed: I started my period a few days into the program. I pulled the instructor aside and informed him of my upcoming menstrual flow, and he assured me it would not be a problem at all.

As far as sharks go, he was right. A woman’s period should not pose a problem since women lose a very small amount of blood during this time and, according to the Diver’s Alert Network (DAN), many shark species are not attracted to the blood anyhow.

As far as Decompression Illness, or DCI, goes, let’s just say I was fortunate.

Decompression Illness may be caused by Decompression Sickness (DCS) which results from nitrogen bubbles that remain in the tissues of the body after one has been in a high-pressure environment, like scuba diving in the ocean. The amount of nitrogen may build up if divers spend too much time at certain depths, scuba dive for too long, or ascend to the surface too quickly.

DCI may also be due to Arterial Gas Embolism (AGE), or gas bubbles in the bloodstream, which have the potential to block the flow of blood to the heart.

The impact DCI has on the body varies from joint pain to death, so divers make sure to reduce the risk of DCI by tracking nitrogen absorption and ascending to the surface slowly (this permits off-gassing, or releasing, of nitrogen bubbles).

Turns out, a woman is more susceptible to DCS during menstruation if she uses oral contraceptive pills, and I take oral contraceptives.

DAN and the British Hyperbaric Association looked at the statistics for 956 female divers with DCI and found that 38% of the women were menstruating when the incident occurred. Of those women, 85% were taking oral contraceptives. Though the data is inconclusive, it suggests that female divers taking the pill have an increased chance of DCI, and DAN suggests oral contraceptive pill-poppers partake in more conservative dives during menstruation.

Luckily, we were taught safe dive practices, and dove to conservative depths within reasonable bottom times. However, looking further into the subject brought to light something I should have known: Most of the health information provided for women divers are based on data from healthy, young men or animals, which is not necessarily adequate.

Dive tables that calculate the nitrogen absorbed by the body are based on the physique of male divers, who have, on average, a lower percentage of body fat than women. Fatty tissues absorb nitrogen at a slower rate than other parts of the body, such as the lungs and abdominal organs, which means they off-gas nitrogen more slowly as well.

Though it’s difficult to say whether these differences significantly increase a woman’s susceptibility to DCI, it does demonstrate how the medicine of diving has been primarily focused on men’s health in particular. Just like the ocean itself, the impact of scuba diving on women’s health is virtually uncharted territory.
