. Suggest three contraceptive methods to control the size of human population which is essential for the health and prosperity of a country

Best Answer

Ans. There are three different methods of contraception:

i.  Barrier methods. In these methods, physical devices .such as condoms, diaphragms and cervical caps are used. These devices prevent the entry of sperm in the female genital tract, thus acting as a barrier between them

ii. Surgical methods. There are surgeries that can be carried out in males and females. In males, a small portion of the sperm duct (vas deferens) is blocked by a surgical operation. This prevents the sperms from coming out.

In females, a small portion of the fallopian tubes (oviducts) is blocked by a surgical operation: It prevents the egg from reaching the uterus. In both the cases, fertilization will not take place

iii. Chemical methods. This category of contraceptives  acts by changing  the hormonal balance  of the  body  so  that  eggs  are  not  released  and  fertilisation  cannot  occur. Females use two types of pills for preventing pregnancies, i.e., oral pills and vaginal into the fallopian tube. This is also called oral contraceptives (OC).             Other contraceptive devices such as loop or the copper-Tare placed in the uterus to prevent  pregnancy.
