Typically, female mouse embryos with two X chromosomes develop ovaries because a gene called Sox9 is suppressed. In male ...

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

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' ...

The first-ever 3D model of testicles, made using mouse cells, could improve our understanding of sex development disorders and male infertility. When you purchase through links on our site, we may ...

Scientists have introduced lab-grown testicle organoids that closely mimic the structure and function of natural testes, offering a potential breakthrough in infertility treatment. Organoids, ...

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, ...

This cross section through several mouse testes shows how sperm are made and maintained. The testes are where sperm cells are made. A human male can produce between 70 million and 150 million sperm ...
