Surgery Helps Men Regain Their Fertility after Cancer
New research shows a painstaking surgical technique can help some men deemed infertile because of childhood cancer treatment to become fathers after all. Surgeons essentially perform tiny biopsies of testicular tissue to hunt any pockets of hidden sperm, which then are used in standard in vitro fertilization to attempt a partner's pregnancy. In cancer survivors, they were able to extract small amounts of sperm from more than a third of the men — 27 of 73. Doctors then attempted injecting the sperm into a partner's eggs in hopes of pregnancy. The result: 20 children were born, including five pairs of twins, the researchers reported Monday in the Journal of Clinical Oncology.
