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 ...

In a report set for publication in the journal Biology of Reproduction, scientists at the University of Pennsylvania and the University of California, Davis, describe a technique that yields fertile ...

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 ...

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 ...

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 ...
