Normal Menstrual Cycle

Slide 4

To understand what creates the state of infertility that occurs among postpartum breastfeeding women, it is important to understand the changes that occur in the menstrual cycle. Scientists have studied the return of fertility among breastfeeding women and compared this with the cycles of non-pregnant, non-lactating women. In non-pregnant, non-lactating women, hormones from the pituitary gland, which are regulated by the hypothalamus, initiate a series of other hormonal changes that cause the development and maturation of an ovarian follicle containing an ovum or egg cell. The follicle secretes estrogen and eventually ruptures, releasing the egg cell. The ruptured follicle forms a temporary gland known as the corpus luteum and begins to secrete progesterone in addition to the estrogen. The estrogen and progesterone cause the lining of the uterus to thicken in preparation for the implantation of the egg cell should it be fertilized. If the egg cell is not fertilized or if it does not implant, the uterine lining is shed during menstruation.
