Stem cell treatment may reverse male infertility

November 2, 2012

Researchers at the University of Pittsburgh implanted frozen sperm-producing stem cells back into lab monkeys after they had undergone chemotherapy treatments.

The stem cells, which had been extracted prior to treatment, successfully fertilized eggs in nine out of 12 trials involving adult monkeys.

Researchers say it gives promise to the idea that human stem cells could be frozen and re-used after treatment without losing their fertility, although more study is needed.
