Male sterility in genes

Anne Chandley and Howard Cook, one of the British directors, have identified on chromosome Y a dozen genes that cause male infertility. Researchers try to better understand why azoospermia or lack of spermatocyte occurs, and then get male contraceptives.

Another controversial application of research would be the genetic recovery of sterility, but that would be the manipulation of the genetic heritage of the human species and ethics generates great controversies.
