Female desire shuts off upstream. 

BRIEFING

A pill for women’s libido finally cleared the medical system, and the reaction has been awkward and uneasy. Part of the delay was scientific. The rest comes down to how female desire still makes people cringe. Time to dive in.

For decades, male and female sexual health were treated as if they existed on different planets. When men experienced erectile dysfunction, medicine moved like lightning, fast, confident, and decisive. There was a reason for that. Erectile dysfunction was easy for regulators to understand. It involved blood flow, physical response, and outcomes that could be measured and repeated. In other words, it was familiar science.

It shouldn’t come as a shock that women’s desire is a different and more complicated story. It lives higher up in the body, in the brain. Because of that, motivation and reward are harder to isolate, measure, and treat, which slowed medicine’s ability to understand and treat it properly.

Also, let’s be honest, female libido probably makes science a little uncomfortable too.

By the early 2010s, researchers finally saw what women had been describing all along. Female sexual desire is primarily neurological. Brain imaging showed that women with low desire were no longer responding to sexual cues the way they once had. Once that difference was visible, desire was no longer abstract or emotional. Now, it was biological, measurable, and legitimate.

When the first treatment for women’s desire finally landed, it was handled very differently than similar drugs for men. Yes, the science was newer, so the outcomes were harder to measure, and as a result, regulators moved more slowly. The labels were much tighter, prescribing rules were way stricter, and access wasn’t always easy.

Now, before anyone grabs the pitchforks and torches, that difference does not mean men hate women. Female desire is more complex, more contextual, and less predictable than male arousal, so medicine tends to slow down when it is dealing with something it cannot easily quantify. The problem is that those early “safety guards” stayed in place long after the data showed they were no longer necessary.

For a long time, those guardrails just stayed put. Men continued to move through the system with sexual health treated as basic routine adult care, while women’s desire was still boxed in by tighter rules and narrower access.

By late 2025, ten years of real-world use had quietly answered the remaining questions. The label expanded, the extra restrictions fell away, and women’s desire stopped being treated as a special case and started being treated like part of normal adult health.

Now, male and female sexual health operate under more similar rules. That’s part science and part culture. But is everyone thrilled about it? Well, yes and no, I’d say. Of course, nobody is suggesting that women should be done with pleasure and excitement after their childbearing years. Still, you can understand why the idea of a surge of horny cougars on the prowl makes some people a little uneasy.

The Little Pink Pill & The Big Fight for Women’s Sexual Health features Cindy Eckert, the founder of Sprout Pharmaceuticals and the woman who led the development and approval of the first FDA-approved treatment for hypoactive sexual desire disorder in women.

The discussion skips the cultural nonsense and sticks to the substance. Eckert walks through how female desire actually works, why it lives in the brain rather than the body, and what a decade of real-world use revealed once the drug was finally hit the market. It’s a grounded look at the science, the data, and the regulatory caution that shaped access early on, and what eventually changed once the evidence had nowhere left to hide.

There’s still more to the regulatory story, including details on how the little pink pill eventually made its way through the system.

SOURCE

Addyi works by addressing neurotransmitters like dopamine, norepinephrine, and serotonin in the brain, balancing them to stimulate sexual desire signals while suppressing inhibitory ones. The pill has been approved by the U.S. Food and Drug Administration (FDA) since 2015 to treat hypoactive sexual desire disorder (HSDD) in pre-menopausal women, and the expanded approval includes women under age 65 who are past menopause, a time when hormone levels drop and libido changes.

The FDA required an additional review of data on women after menopause to ensure the drug’s safety and efficacy in the larger age group—a requirement that Cindy Eckert, Sprout’s CEO, says represents a double standard and stigma against addressing sexual desire in women, since that data was part of the company’s original submission for approval and included women 18 to 80 years old. Eckert discussed with TIME the company’s long road to the approval and the larger issues facing certain medicines for women.

The latest regulatory update explains why daily treatment for low sexual desire was expanded to include postmenopausal women and what changed to allow that shift. It focuses on how the medication works in the brain, who it’s meant for, and how safety is evaluated when the goal is quality of life.

The approval didn’t come out of nowhere. It followed years of real-world use showing the mechanism still mattered after menopause. Once that data piled up, the rules adjusted.

On December 15, 2025, the U.S. Food and Drug Administration (FDA) approved the medication Addyi (flibanserin)Trusted Source for the treatment of hypoactive sexual desire disorder (HSDD) in postmenopausal women under the age of 65.

Addyi was previously approved in 2015 for the treatment of HSDD in premenopausal women. Premenopause or “before” menopause refers to the reproductive time in a cisgender woman’s life when they have regular menstrual cycles.
Postmenopause refers to the time period after the person finishes menopause and no longer has a menstrual cycle. The majority of people start menopause between the ages of 49 and 52Trusted Source.
While people can experience HSDD at any age, it is not uncommon to experience a low libido during menopause and postmenopause. Past research shows that between 40-55% of women advancing through menopause experience low sexual desire, and about 9% of postmenopausal women have HSDD.

DEBRIEFING

This story is less about a breakthrough and more about a slow course correction. Female desire didn’t suddenly change. The system just got better at studying it, measuring it, and treating it without so many extra guardrails.

What ultimately changed wasn’t biology. It was the timing, comfort with the data (less cringe), and a set of restrictions that loosened up once the evidence piled up.

NOW YOU KNOW

Ten years later, the system finally got in the mood.
