Nutritional: negative energy balance, young or primiparous animals are more susceptible, mil production can be an impact. Dogs do not have lactational anestrus because of cycle. Cats are hard to predict or uniform responses. Is the events that occur between two successive menstrual periods. Ranges from 24 to 35 days usually 28. Menses is the sloughing of the endometrium to exterior menstrual period. Follicular phase and luteal phase are equal. Differences from the estrus cycle: no defined period of sexual receptivity, period of endometrial sloughing (menses, begins and ends with menses not ovulation. Follicular phase produces estradiol is 14 days long: 9 proliferative phase, 5 menses. Luteal phase is secretory phase and lasts 14 days. Changes in endometrial thickness in response to estradiol and progesterone. Menopause is the human version of anestrus: unlike nutritional , lactational or pregnancy, depletion of follicles on the ovary. Lack of cyclicity, acyclicity or menses is called amenorrhea: similarly to anestrus.
