Beneath the surface of the vaginal wall, a handful of bacterial species run one of the most efficient chemical operations in human biology. Researchers have spent the last two decades learning their names — and discovering that the community they build is far less uniform than textbooks once…

The clip runs about eleven seconds. A wide ceramic bowl sits inside a wooden stool, dried petals turning slowly in the water, a linen sheet draped over a woman's knees. Steam curls upward through a shaft of afternoon light. The caption is a single line, usually a promise. The comment section,…

For close to fifty years, one number did all the work. Eight thousand nerve endings: printed in magazines, repeated in health pamphlets, handed out in classrooms, quoted by physicians on television, and eventually absorbed into the general knowledge of an entire culture. It had the clean, settled…

The Scene We Were All Sold. You know the shot. The bedroom is lit like a perfume advertisement. She crosses the room in something ivory and bias-cut, the hem moving the way fabric only moves when a stylist has spent an hour on it, and she slides under a duvet that has never once been kicked off at…

There is a question almost no one thinks to ask, yet the answer turns out to be quietly extraordinary: what does mother's milk actually taste like? Not in a clinical sense, not reduced to its macronutrient chart — but as something a woman makes, something alive and warm and variable, a substance…

For more than a century, nearly everyone agreed on the story: the vibrator was built so Victorian doctors could relieve their female patients of "hysteria." It is a wonderful story. It is also, according to the documented record, mostly untrue — and the real history is far stranger.

Ask most women to point out the clitoris on a diagram and the finger lands in the right place immediately. Ask what shape the rest of it takes, and the answers thin out fast. That gap is not a lapse of attention. It is a lapse in the material: for most of the twentieth century, the diagrams handed…

The human body runs two separate sweat systems, and only one of them was built for cooling. The other — the apocrine system — sits in a narrow set of places: the underarms, the areolae, and the sub-pelvic and perineal region. It stays dormant through childhood, switches on at puberty, and produces…
