Physiology of Lactational Amenorrhea – Mechanism of Action

Slide 5

This cycle of events is sometimes modified, as when a woman becomes pregnant or breastfeeds. When a woman breastfeeds, the stimulation of the nipple by the infant’s suckling sends nerve impulses to the mother’s hypothalamus, which responds by changing the production of the pituitary hormones. As described earlier, these hormones are needed to stimulate ovulation. Without this stimulation, the ovaries do not produce a ripe egg or prepare the uterus for pregnancy. Therefore, there is a time when breastfeeding women do not ovulate or have menstrual periods. Hence the term, “lactational amenorrhea” — which is a lack of menses resulting from breastfeeding. As we will discuss later in the presentation, the lack of menses is usually a sign of temporary infertility.

The infant’s suckling is the stimulus that initiates the state of lactational amenorrhea for breastfeeding women. Women choosing to use LAM for contraception maintain lactational amenorrhea and infertility by breastfeeding intensively.
