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.

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, ...

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 ...

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 ...

Rat testicle cells that were frozen for 23 years have produced sperm after being implanted into mice. The findings suggest that children who have testicle tissue frozen before cancer treatment may be ...

If humans had a similar body ratio to the northern giant mouse lemur, their testicles would be the size of grapefruits.
