Research from University College London has shown that male flies that are genetically programmed to produce only female offspring compensate for their low sperm count by growing larger testes. Male ...

The testis is responsible for sperm production and testosterone synthesis. Abnormalities in testis development and function lead to disorders of sex development (DSD) and male infertility. Currently, ...

Researchers at Israel's Bar-Ilan University have grown "laboratory testicles" they hope could eventually ease male infertility, which affects 10% to 15% of American men. This is pretty nuts — ...

A team led by University of Osaka researchers has developed a technique to generate testes from mouse embryonic stem cells ...

A testis produced from human cells, for example, could help children being treated for cancer, which may impair their ability to produce functional sperm. As children are too young to produce their ...

A breakthrough study published in PLoS Biology demonstrates that rat testis tissue frozen for over 20 years can be successfully transplanted into infertile mice to regenerate and produce sperms.

Researchers at the Smithsonian Conservation Biology Institute (SCBI) have generated mature sperm from frozen testicular tissue for the first time. Their findings were published in PLOS ONE today. The ...

(Gray News) Researchers at Israel’s Bar-Ilan University have successfully created artificial testicles in a lab to help with sexual infertility. According to the study, infertility is experienced by 1 ...
