After cancer, stem cells bring back male fertility


After an injection of banked sperm-producing stem cells, male primates who become sterile due to cancer drug side effects were once again fertile.

“This study demonstrates that spermatogonial stem cells from higher primates can be frozen and thawed without losing their activity, and that they can be transplanted to produce functional sperm that are able to fertilize eggs and give rise to early embryos,” says Kyle Orwig, associate professor in the department of obstetrics, gynecology, and reproductive medicine at the University of Pittsburgh School of Medicine.
