उत्तर

India’s population is rapidly expanding, demanding the widespread use of prevention to keep all fertile couples under control. It will help reduce the birth rate, limiting population expansion. Therefore, the use of contraception is justified. It is crucial to remember that selecting an effective contraceptive method requires consultation with experienced specialists. The government provides these services free at family planning centres. These facilities provide contraceptives for free or at a low cost to couples of reproductive age who want to avoid pregnancy.
