Stem cells could provide sperm for infertile males

Researchers have been successful in creating sperm-producing germ cells from stem cells in a lab and transferred them into infertile mice, which after the treatment were able to produce healthy offspring. This new development could help thousands of infertile men become fathers if the method proves similarly effective in humans.

Mouse sperm created in lab: Hope for male infertility

In a scientific breakthrough, researchers report that they've grown mouse sperm from testicular tissue in the laboratory, a development that could advance the field of infertility in human males. Although still proven in mice, “this is a small but important step in understanding how sperm are formed, which may, in time, lead to us being able to grow human sperm in the laboratory,” said Dr. Allan Pacey, senior lecturer in andrology at the University of Sheffield in England, who is familiar with the study results.

First step in development of artificial human testicle

After more than 30 years of unsuccessful efforts by numerous investigators, researchers have now found a way to propagate primary human Sertoli cells in the laboratory. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body.
