Scientists supported by the National Institutes of Health have a new theory as to why a woman’s fertility declines after her mid-30s. They also suggest an approach that might help slow the process, enhancing and prolonging fertility.
They found that, as women age, their egg cells become riddled with DNA damage and die off because their DNA repair systems wear out. Defects in one of the DNA repair genes—BRCA1—have long been linked with breast cancer, and now also appear to cause early menopause.
“We all know that a woman’s fertility declines in her 40s. This study provides a molecular explanation for why that happens,” said Dr. Susan Taymans, Ph.D., of the Fertility and Infertility Branch of the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD), the NIH institute that funded the study. “Eventually, such insights might help us find ways to improve and extend a woman’s reproductive life.”
The findings appear in Science Translational Medicine.

Wait, where did the sun go? This week’s guest post comes from the lovely hand-letterer and typeface designer Victoria Rushton.
Anytime I ever say this, it is the biggest lie I could ever possible tell anyone, including myself. Once my head hits the pillow I’m OUT for at least…I don’t know…3 or 4 hours? I don’t think that justifies as “quick” in any sense.
