Question

what is the nee of using contraceptives?

Answer 1

contraceptives are used to avoid pregnancies. this is useful due to the following reasons:
Many adolescents may be sexually active. this age group may be biologically capable but not mentally. neither of the partners may be adults and becoming a parent is a huge responsibility as you are guiding the next generation.

Sometimes couples may just want to have sexual experiences but not want children. contraceptives allows them to do this. in olden days when there were no contraceptives many families had many children because of frequent unpreventive sexual intercourse.

sometimes contraceptives are used to prevent diseases as well as condoms have a 97 % rate of stopping AIDS.
thus the use of contraceptives is a bane for the world.
