The different methods of contraception are as follows:
1. Natural method: It is the method of avoiding the chances of fertilization. Sexual intercourse is avoided from day 10th to 17th of the menstrual cycle. As this is the period of ovulation and chances of fertilization are high.

2. Barrier method: This method includes prevention of mating of ovum and sperm with the help of barriers. Barriers are available for both males and females. For example, condoms.  A condom is the kind of contraception that protects a person from pregnancy and also from acquiring a sexually transmitted disease, up to some extent.

3. Oral contraceptives: Tablets are taken orally that have small doses of hormones. This prevents the release of eggs. Thus, fertilization cannot take place.

4. Implants and surgical methods: It includes the use of contraceptive devices such as the loop or Copper-T. A common metal device used for preventing pregnancy is copper-T or IUCD (Intra-Uterine Contraceptive Device). Devices like IUCD or copper-T prevent the implantation of a fertilized egg cell (or embryo) in the uterus of the female. This method of contraception cannot protect a woman from acquiring STD.

In another method, gamete transfer is blocked by surgery. In a vasectomy, blocking of vas deferens is done to prevent the transfer of sperms. In tubectomy, the fallopian tubes of the female are blocked thus the egg cannot reach the uterus.

Contraception is an artificial method practiced to avoid pregnancy during sexual intercourse. The contraception method prevents pregnancy by either restricting the production of eggs; restricting fertilization of eggs with sperm; or restricting fertilized eggs to implant in the uterus.

The advantages of adopting contraception methods such as condoms are:

(i) It prevents the fertilization of eggs and sperm, thereby avoiding the chances of getting an unwanted pregnancy.

(ii) Using barrier methods like condoms protects the persons involved in a sexual relationship from sexually transmitted diseases.]
