It's a commonly held belief: Sperm cells are like runners in an epic race, competing against each other for access to the coveted egg at the finish line. The egg, in turn, waits patiently for the winning sperm to pierce its outer membrane, triggering fertilization.

In her new book "The Stronger Sex: What Science Tells Us about the Power of the Female Body" (Seal Press/Hachette, 2025), science writer Starre Vartan addresses this and other pervasive myths about the female body, highlighting what science actually tells us about differences in biology between the sexes and where gaps in knowledge still exist, in part, due to a historic lack of research focused on females.
