Hormonal birth control methods employ hormones like estrogen, progestogen or a combination of both in case of females. These hormones inhibit ovulation, make uterus unsuitable for implantation and thus prevent pregnancy.
Levonorgestrel is a progestogen (synthetic form of progesterone) used in contraception for females.
Testosterone is used in male contraceptive pills.
LH (Luteinising hormone) is generally not used directly in contraceptive preparations.
