Lactaional Amenorrhea

Lactational amenorrhea (LA) is a natural form of contraception that is based on the physiological changes that occur during breastfeeding. It is a method of contraception that is used during the first six months of postpartum. LA is a safe and effective method of contraception when used correctly. LA works by suppressing ovulation and preventing pregnancy. This is achieved by the increased levels of prolactin and oxytocin when breastfeeding. The hormones cause the hypothalamus to inhibit the release of gonadotropin-releasing hormone (GnRH), which prevents the release of follicle stimulating hormone (FSH) and luteinizing hormone (LH). Without the release of these two hormones, ovulation does not occur. In order for LA to be effective, there are certain criteria that must be met. These include exclusive breastfeeding (no formula, pumping, or solids), frequent breastfeeding (at least every four hours during the day and every six hours at night), and the baby being less than six months old. It is important to remember that LA is not 100% effective in preventing pregnancy. There is still a risk of pregnancy, even when all the criteria are met. Therefore, it is recommended to use a backup method of contraception if relying on LA. This can include condoms, hormonal contraception, or an intrauterine device (IUD).
