Male infertility afflicts about 50% of all infertile couples. Pregnancy usually happens in about 80-85% of couples within one year of trying, and in about 15-20% of couples it takes longer than one year of trying to get pregnant.
Sperm usually die inside the vagina within less than an hour but they can survive inside the uterus for up to 5 days.
