New findings indicate that reimplanted childhood testicular tissue can produce sperm in adulthood, supporting experimental fertility preservation strategies.

For the first time, frozen testicular tissue collected from a patient when they were a child has been successfully ...

In the battle of the sexes, males appear to have the innovative edge--from a genetic standpoint, at least. Scientists are finding that the testes are more than mere factories for sperm; these organs ...

In boys with undescended testis, the risk of developing infertility is traditionally predicted based on a decrease in germ cell count observed using testicular biopsy samples. However, the process of ...

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 ...

In a small number of people, testicular cancer can run in families. Having a parent or brother with testicular cancer can increase a person’s risk of getting it. Also, some inherited conditions can ...

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 ...
