Boys whose testes have not descended into the scrotum at birth may be nearly three times more likely to develop testicular cancer later in life, according to a new study. An increased risk of ...

A team of researchers has reported a breakthrough in making sperm cell precursors in vitro that could be used in a number of ...

In science, we don't often get to talk about male repression, but a new discovery gives us just such a chance. It turns out that ovaries can only remain ovaries by constantly suppressing their ability ...

Mutant sperm-factories spread in men's testicles as they age to increase the risk of children with genetic diseases, researchers have shown. Millions of spermatogonia produce a constant supply of ...

Male infertility is a serious issue, often caused by low sperm counts. Now, researchers at Seoul National University have developed a way to deliver nanoparticles loaded with certain proteins directly ...

Researchers say they have found a way to pluck out a potent type of stem cell from the testes of adult mice and transform it into other kinds of tissue, including heart muscle and blood vessels. The ...

Researchers have located one more anatomical organ where microplastics — of all shapes and constituents — are found: human testes. And although they can’t say for sure, they suspect the presence of ...

Resolving the evolution of soft-tissue structures, crucially depends on accurate knowledge of the evolutionary relationships between the considered species. If these relationships are not fully ...

Scientists have succeeded in isolating stem cells from human testes. The cells bear a striking resemblance to embryonic stem cells -- they can differentiate into each of the three main types of ...
