When a man finds out he has cancer, sex doesn’t tend to be the first thing on his mind. Survival is. But that’s not to say that the impact of a cancer diagnosis on sex, and more particularly on his ...

Ultrastructure expansion microscopy of murine male germ cells reveals the fine molecular structures of centrioles (shown in the enlarged image). DNA is stained in blue, and the chromosome axis in red.

By studying the genes responsible for the seahorse’s brood pouch, researchers uncovered a new route to “motherhood.” ...

Male bonobos are able to interpret female fertility cues even when those signals do not reliably indicate ovulation. This ability helps them direct their mating efforts toward times when conception is ...

Reproductive biology involves the scientific study of the reproductive system. Improved understanding of reproductive biology can lead to new treatments for reproductive disorders, such as infertility ...

Cleveland’s iconic prehistoric sea monster—the 14-foot-long armored fish Dunkleosteus terrelli—just got a lot stranger. This marine apex predator lived some 360 million years ago, had razor-sharp bone ...
