a) Coitus Interrupts
It is a very unreliable contraceptive method where the coitus is stopped before the
male ejaculates inside the female reproductive tracts.

b) Rhythm Method
Another unreliable method of contraception where the coitus is avoided when the
female is fertile and the chances of fertilization are very high.

5. Surgical Method (Sterilization)

 Sterilization is a surgical method of going permanently sterile.
 This can be done in both males and females. Permanent
contraception methods of sterilization prevent pregnancy permanently.
 Vasectomy is a surgical procedure for male sterilization or permanent
contraception.
 During the procedure, the male vasa differentia are cut and tied or sealed so as to
prevent sperm from entering into the urethra and thereby prevent fertilization of a
female through sexual intercourse.

 Tubectomy, also known as tubal sterilization, is a permanent method of
contraception in women.
 It is a surgical process that blocks the fallopian tubes, thereby preventing the egg
released by the ovary from reaching the uterus.

Surgery can also be used for removal of unwanted pregnancies. These may be misused by
people who do not want a particular child, as happens in illegal sex-selective abortion of
female foetuses. For a healthy society, the female-male sex ratio must be maintained.
Because of reckless female foeticides, child sex ratio is declining at an alarming rate in
some sections of our society, although prenatal sex determination has been prohibited by
law.
