7 Contraceptive Methods To Prevent Pregnancy

Natural Methods

The rhythmic method or periodic abstinence - It is a method where mating between couples is avoided from 10–17 days of the menstrual cycle of a female when ovulation could be expected. It is based on the principle that ovulation occurs on the 14th day of the cycle, sperm lives maximum up to 2-3 days and ovum becomes viable for 1-2 days. As chances of fertilization are high during this period, conception should be prevented. 

Coitus Interruptus - In this method male partner withdraws his penis from the vagina canal before ejaculation to avoid insemination. 

Lactational amenorrhea - During the period of lactation in females due to the high level of prolactin and gonadotrophin hormone released and less release of estrogen and progesterone hormone ovulation stops. Hence pregnancy is prevented as menstruation doesn't occur.

Barrier Methods

Condoms - These are thin rubber sheath used to cover the penis of the male or vaginal canal of females just before coitus so that ejaculated semen is not released in the female reproductive tract. Nirodh is a popular brand of male condoms. 

Cervical cap and Diaphragm - These are mainly made up of rubber and are placed in the female reproductive tract in the cervix region to prevent the entry of male gamete.

Chemical Methods

Spermicidal creams, jellies, and foams when applied to the vaginal canal cause the death of sperms. They are a mixture of citric acid, lactic acid, boric acid, etc. Delfin is a popular brand of spermicide.

Sterilization Method

Tubectomy - In women, the Fallopian tubes may be cut, tied, clamped, or blocked.

Vasectomy - In males, vas deferens is cut and ligated to prevent sperm from joining the unfertilized egg.
