Pills always contain either progesterone alone or a combination of both estrogen and progesterone. These hormones' presence in little excess can prevent ovulation as they suppress the activity of FSH and LH.
Condom is a tubular latex sheath that fits over the penis and traps the ejaculated sperms during coitus. Femidom which is also known as the female condom or internal condom is a barrier device that is used during sexual intercourse to reduce the probability of pregnancy. During intercourse thin silicone sheath of femidom collects the ejaculated semen.
Saheli is a non-steroidal pill which modifies the estrogen receptors in the uterus, which prevents the proliferation of the endometrial lining of uterus. This makes it unsuitable for implantation of the embryo.
CuT is copper releasing IUDs which has a spermicidal property that increases phagocytosis of sperms inside the uterus, suppressing sperm motility.
