Breastfeeding amenorrhea contraception strictly requires mothers to breastfeed or almost exclusively breastfeed their babies because the sucking of the nipple by the baby can stimulate the mother ’s anterior pituitary to secrete prolactin and the posterior pituitary to secrete oxytocin to suppress gonadotropins The release of hormones, thereby inhibiting ovarian ovulation, to achieve the purpose of contraception. However, it is not difficult to find in life that many mothers are pregnant unexpectedly during lactation, a large part of which is because they have not grasped the implementation standards of lactation amenorrhea contraception.
