7Removal of gonads cannot be considered as a contraceptive option. Why?Show solution
Removal of gonads cannot be considered a proper contraceptive option because contraceptives should preferably be reversible and should not unnecessarily interfere with normal reproductive function. Removal of gonads is a permanent and radical step, unlike ordinary contraceptive methods. It is not a normal method of birth control for family planning.
