Proper development of the fetal penis requires not just testosterone from the testes, but a second hormone produced by other tissues, including the placenta, according to a new study publishing ...

A common birthplace of new genes, the male testes are a hotspot for biological innovation. Within these organs, scientists have found a trove of virgin genetic sequences -- and a better understanding ...

Researchers have created lab-grown testicle organoids that closely resemble the real thing. The breakthrough provides a promising model for research that may advance our understanding of the organs' ...

Many people with testicular cancer don’t have a family history of it. Still, your risk may be much higher if you have a parent or sibling with the disease. But environment and hormones also play a ...
