Question

why is cu-t considered as a good contraceptive device to space children

Answer 1

Copper T is IUCD (Intra Uterine Contraceptive Device). It simply decreases the viability of sperms entering the female reproductive tract. Release of these copper ions creates spermicidal environment that destroys the sperms thus preventing the fusion of sperm with the egg and hence prevents pregnancy. It is effective for long duration and that is why it is a good contraceptive device to space children.
