U.S. Fertility Rates Drop to Another Record Low - The U.S. fertility rate fell to another record low in 2025, extending two decades of declines, according to federal data released on Thursday. The drop began during the Great Recession (2007), following a common historical pattern. However, the rate has continued to drop, and epidemiologists have been trying to understand why. https://www.nytimes.com/2026/04/09/us/fertility-rates-decline.html?smid=nytcore-ios-share

“Scientists are making inroads in understanding one of the central mysteries of human reproduction: Why do women’s eggs deteriorate as they age?” https://www.bostonglobe.com/2026/01/09/nation/scientists-find-new-clues-why-female-fertility-declines-with-age/

“As she -- and her friends — approached the age of 35, senior correspondent Molly Webster kept hearing a phrase over and over: “fertility cliff.” It was a short-hand term to describe what she was told would happen to her fertility after she turned 35 — that is, it would drop off. Suddenly, sharply, dramatically. And this was well before she was supposed to hit menopause. Intrigued, Molly decided to look into it — what was the truth behind this so-called cliff, and when, if so, would she topple?

This story first premiered in “Thirty Something,” a 2018 Radiolab live show that was part of, Go**ds, (https://radiolab.org/series/radiolab-presents-gonads) a six-episode audio and live event series all about reproduction and the parts of us that make more of us. The live event was produced by Rachael Cusick and edited by Pat Walters.

Special thanks to epidemiologist Lauren Wise, at Boston University. Plus, Emily, Chloe, and Bianca. And of course, Jad Abumrad.”

❗️New paper out now❗️

Female sexual function is important for reproductive health, relationship satisfaction, and positive sexual expression. Sexual function may be sensitive to environmental chemicals, but remains largely understudied in EH.

In their new paper, Dr. Samantha Schildroth and colleagues investigated associations of preconception phthalate exposure with validated measures of female sexual function in Pregnancy Study Online (PRESTO). These findings suggest a complex relationship between phthalate exposure and sexual function, highlighting the need for additional research on female sexual function to inform clinical practice.

Dr. Schildroth will be presenting on these findings at ISEE/ISES next Wednesday in the “Environmental chemicals and reproductive outcomes” session.

“Human eggs don't accumulate as many mutations with age as we thought
Mitochondrial mutations don't seem to build up in women's eggs as they age, which suggests they may have evolved a mechanism to avoid this.”
