Male infertility is any condition where the male partner in a couple adversely affects the couple’s chance of pregnancy due to abnormal semen or sperm quality. Infertility is a common, but complex problem affecting about 15% of couples. In about one-third of couples, the infertility is related, at least in part, to male infertility factors.
