What the Pill Actually Did to Women

The chemical element of the feminist program nobody controls for

A reader left a comment on my article, “What Feminism Actually Delivered”, pointing out that there is a layer to the female happiness collapse that the academic literature rarely accounts for. They called it the chemical variable. They are right - and as it turns out, I have been writing about this for years.

This is the follow-up piece.

In The Top Shelf Man, I dedicated an entire section of the hypergamy chapter to Hormonal Birth Control - what it does to female mate preferences, what it does to her libido, and what I believe it is doing to the divorce rate. The research since then has only made the case stronger. When you line it all up, the pill is one of the most consequential social experiments in human history, and the results are in.

They are not good.

What the Pill Actually Does

The mechanism is simple, and I covered it directly in The Top Shelf Man.

“Hormonal Birth Control (HBC) works by putting women in a perpetual state of imagined pregnancy, and that often shifts her preference for men dramatically.”

That is not a fringe claim. That is the established pharmacological reality of how hormonal contraception operates. It overrides the natural hormonal cycle - the ovulatory shifts, the testosterone surges, the biological signals that drive genuine attraction - and replaces all of it with a flat, synthetic hormonal state that mimics early pregnancy.

The downstream effect on mate selection is exactly what you would expect. A woman in early pregnancy is not looking for the dominant, testosterone-signaling alpha who lit her up at the foam cannon party. She is looking for a stable, predictable provider who is going to be around. As I wrote: “Women on HBC show less preference for hyper-masculine traits, as the hormonal cues driving these preferences are muted, and there is a shift towards stability-oriented partners.”

In plain language: “While she’s on HBC, her preference is basically for beta men.”

She May Have Married the Wrong Man

This is the part that should be in every conversation about the modern divorce rate, and it almost never is.

Researchers have known for years that women’s mate preferences shift significantly depending on whether they are on hormonal contraception or cycling naturally. The most compelling line of research involves MHC genetics - the Major Histocompatibility Complex, the immune system genes that produce the biological compatibility signals women unconsciously detect through scent.

Off the pill, women are consistently attracted to men with different MHC profiles - men whose immune genetics complement their own, producing healthier offspring. This preference is powerful, deeply embedded, and entirely below the level of conscious thought. It is her biology running its vetting protocol.

On the pill, that preference reverses. Women on hormonal contraception tend to prefer men with similar MHC profiles - men who, genetically speaking, are less compatible. The signal that should be pointing her toward the right man is chemically suppressed. Alvergne and Lummaa’s 2010 review in Trends in Ecology and Evolution documented this shift and raised the obvious question: what happens when she comes off the pill?

The answer is exactly what you would predict. She stops finding him attractive.

I said it directly in The Top Shelf Man: “Quite often, women spend their 20s or 30s on HBC for the duration of the relationship, and when she gets married, and comes off HBC to start a family, she surprisingly finds herself no longer as attracted to the man she married when her menstrual cycle returns.”

I called it a strong contributor to the high divorce rate in the West. The MHC research explains exactly why.

The Depression Nobody Is Talking About

Here is the data point that should have ended this experiment fifty years ago, and instead got buried.

In 2016, Skovlund and colleagues published a study in JAMA Psychiatry that tracked one million Danish women over fourteen years. The finding was unambiguous: hormonal contraception was significantly associated with subsequent first diagnosis of depression and subsequent antidepressant use. The association was strongest among adolescents. The study controlled for prior depression, socioeconomic factors, and other confounders.

One million women. Fourteen years. The New England Journal of Medicine.

Now go back to the female happiness studies I cited in the last article. Stevenson and Wolfers identified the paradox in 2009 - women getting objectively freer while reporting declining wellbeing. Blanchflower and Bryson’s 2024 analysis confirmed the paradox had resolved into outright reversal - men are now happier on every measure.

These happiness researchers controlled for age, education, employment, marital status, income, health, and country. Not one of those studies controlled for hormonal contraception use. Not one.

In the decades that female happiness was collapsing, hormonal contraception use was climbing. The same decades. The same populations. And the largest study ever conducted on the subject found a significant association between the pill and depression.

Nobody in the mainstream is connecting these dots. You are reading this because you already know why.

The Libido Paradox

This is the one that should make every woman who has ever been handed a prescription for hormonal contraception genuinely angry.

The cultural narrative of the pill as sexual liberation is perhaps the most successful piece of pharmaceutical marketing in history. The pill was freedom. The pill was power. The pill was how women took control of their bodies and their sexuality.

What the pill actually does: it reduces free testosterone in women by elevating sex hormone-binding globulin, which binds and deactivates the testosterone that drives female libido. Panzer and colleagues documented this in 2006, and it has been replicated since.

As I wrote in The Top Shelf Man: “HBC can also lower the libido in some women by reducing free testosterone and stabilizing the hormones that drive her libido.”

The chemical that was supposed to liberate female sexuality biologically suppresses it. Women were handed a tool for sexual freedom that chemically reduces their desire for sex, alters their attraction to the men they are with, and is associated with clinical depression - and the medical establishment spent fifty years calling it progress.

If the pharmaceutical industry had designed a product to quietly undermine female wellbeing while appearing to enhance it, it would look exactly like this.

The Divorce Connection

I want to be direct about what I believe is happening here, because it connects everything.

A woman spends her twenties on hormonal contraception. Her preferences are shifted toward beta traits - stability, emotional warmth, provision. She meets a man who satisfies those suppressed, pregnancy-state preferences. They get married. She comes off the pill to start a family.

Her cycle returns. Her natural hormonal vetting protocol comes back online. She smells him differently. She feels differently about him. She cannot explain it, and her inability to explain it makes her call it falling out of love. What is actually happening is that she is meeting her husband for the first time with her biology intact - and discovering that the version of herself who chose him was running on a pharmaceutical substitute for her actual preferences.

I wrote it plainly in The Top Shelf Man: this is “a strong contributor to the high divorce rate we see today in the West.”

Women initiate approximately eighty percent of divorces. The average marriage that ends in divorce does so within eight years - which is often right in the window of coming off HBC to have children, going through the hormonal reset, and discovering the attraction is gone. The family court system is waiting at the finish line when she gets there.

Nobody is talking about this. The divorce statistics get reported. The family court destruction gets reported - briefly, and poorly. The pharmaceutical mechanism underneath it gets no coverage at all.

What To Do About It

If you are in a relationship and thinking seriously about the long term, this matters in a very practical way.

I put my recommendation directly in The Top Shelf Man: “it’s better for a long-term relationship with a woman to keep her off HBC, and let her cycle run naturally - especially if you are considering children or marriage.”

The alternatives exist and they work. A copper IUD is non-hormonal and 99% effective at preventing unwanted pregnancies. Apps like Natural Cycles paired with an Oura ring are FDA-approved and highly effective when used correctly. These are not fringe alternatives - they are medically established, widely available, and they do not flood her body with synthetic hormones that override her natural mate-selection biology.

If the attraction she has for you was formed while she was on hormonal contraception, you should want to know what happens when she cycles naturally. Better to find out before the marriage, the mortgage, and the kids - not after.

Dr. Anthony Jay made this point from the endocrine side at the 1% Forum last year: the xeno-estrogens accumulating in the modern body - through plastics, fragrances, and synthetic hormones - are systematically disrupting the hormonal environment that human biology was built to operate in. The pill is not separate from that problem. It is the most direct version of it, swallowed voluntarily every morning by hundreds of millions of women who were told it was liberation.

In Conclusion

“What Feminism Actually Delivered” documented the outcome: women are objectively less happy by every available measure, despite fifty years of objective progress. This article documents one of the mechanisms.

Hormonal contraception shifts women toward beta men. It suppresses the biological signals that drive genuine attraction. It is associated in a landmark million-woman study with depression and antidepressant use. It reduces free testosterone and with it female libido. It may cause women to select genetically incompatible partners and then lose attraction when they come off it. And it has been universally presented as a tool of female empowerment while quietly delivering the opposite.

The feminist program handed women legal rights, career access, and the pill. I covered what the legal rights and career access produced in the last article. The pill deserved its own piece.

The building blocks of female unhappiness are not mysterious. They are documented, peer-reviewed, and sitting in plain sight. The institutions that delivered those building blocks have no interest in admitting it.

Unplug. Read the data. Draw your own conclusions.

The Cold, Hard Truth

Never forget:

• Hormonal Birth Control puts women in a perpetual state of imagined pregnancy, shifting their preferences toward beta, stability-oriented men. Her attraction under HBC is not her natural attraction. Those are not the same woman.

• Women on HBC show suppressed preference for masculine traits and reduced libido from lower free testosterone. The chemical designed to liberate female sexuality biologically reduces it.

• A 2016 JAMA Psychiatry study tracking one million women over fourteen years found hormonal contraception was significantly associated with first diagnosis of depression and antidepressant use. Not one of the major female happiness decline studies controlled for this variable.

• Coming off HBC after marriage to start a family frequently triggers loss of attraction for the man she chose under hormonal influence. Her cycle returns, her biology comes back online, and she meets her husband for the first time with her actual preferences intact. The divorce statistics follow.

• If you are serious about a long-term relationship, it is better for her to cycle naturally. The attraction that forms off HBC is the attraction you can count on. The alternatives to hormonal contraception - copper IUD, Natural Cycles, Oura ring - are established, effective, and do not override her biology.

• The happiness researchers never controlled for hormonal contraception use. The pharmaceutical mechanism behind the female happiness collapse is sitting in plain sight in the academic literature. It is not being discussed. That absence is the story.

Peace.
