Human reproduction is any form of sexual reproduction resulting in human fertilization, typically involving sexual intercourse between a man and a woman. During sexual intercourse, the interaction between the male and female reproductive systems results in fertilization of the woman's ovum by the man's sperm, which after a gestation period, typically for nine months, is followed by childbirth.
Beginning at puberty and continuing for their entire lives, men produce sperm, often more than 100 million per day. The process of sperm production called spermatogenesis, is similar among most mammals and requires 9-10 weeks in humans. In this section we examine the structures of the male reproductive system and the production of sperm and semen, a fluid expelled at ejaculation that usually contains sperm.
