Elevated prolactin levels and a reduction of gonadotropin-releasing hormone from the hypothalamus during lactation suppress ovulation. This leads to a reduction in luteinizing hormone (LH) release and inhibition of follicular maturation. The duration of this suppression varies and is influenced by the frequency and duration of breastfeeding and the length of time since birth.   This method requires 1) breastfeeding of the baby every 4 hours during the day and every 6 hours at night, 2) no supplementation of other foods or formula, 3) no return to menses, and 4) the baby must be less than six months old for perfect use.
