hypothalamic amenorrhea - the inability to ovulate may be the result of a disorder of the hypothalamus.
-
hyperprolactinemia - tumors of the pituitary gland (adenomas) cause the secretion of high quantities of prolactin, the hormone normally produced after childbirth and which stimulates the breasts to produce milk. Prolactin inhibits the intermittent release of GnRH, thus preventing gonadotropin secretion, follicular development and ovulation, leading to amenorrhea. For this reason, breastfeeding is associated with a strong reduction (but not the total absence) of fertility

excessive exercise - ovulation can be suppressed in women who exercise at extreme levels (e.g. swimming, running, frequent gym attendance, etc.)
