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 ...

After a decade of research, Howard Hughes Medical Institute scientists have succeeded in reprogramming adult stem cells from the testes of male mice into functional blood vessels and contractile ...

Easily accessed and plentiful, adult stem cells found in a male patient's testicles might someday be used to create a wide range of tissue types to help him fight disease -- getting around the need ...

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, ...

A previously unrecognized genetic cause for two types of birth defects found in newborn boys has described in a report. Cryptorchidism is characterized by the failure of descent of one or both testes ...

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 ...

Discovery of how a protein called SMAD3 behaves has given new insights into puberty development in boys and fertility in adult men; the researchers also hope it will lead to a better understanding of ...

Humans are sexual, meaning that both a male and a female are needed to reproduce. Each is equipped with specific organs capable of producing specific cells needed to procreate. In conjunction with a ...

Male hypogonadism means your body isn’t making enough testosterone, the hormone that plays a role in drive, energy, and muscle strength. Primary hypogonadism starts … ...

Dr Mark Green receives funding from the National Health and Medical Research Council, as well as the University of Melbourne for his research on fertility and endocrine disruptors. He is the Secretary ...

A potential new male contraceptive drug has just undergone its first tests in human volunteers. The results give the first indication that the drug, which does not use artificial hormones or affect ...
