Fertility can be controlled by a variety of hormonal and nonhormonal methods of contraception:
oral contraceptives that contain hormones to inhibit FSH production so that no eggs mature
progesterone to inhibit the maturation and release of eggs for a number of months or years
barrier methods such as condoms and diaphragms which prevent the sperm reaching an egg
intrauterine devices which prevent the implantation of an embryo or release a hormone
spermicidal agents which kill or disable sperm abstaining from intercourse when an egg may be in the oviduct
