The rat estrous cycle lasts 4 days. During this time, the uterine lining builds up and is then shed if fertilization does not occur. Ovulation is required for fertilization to occur, but not necessary for sexual behavior during the estrous cycle. Adrenal hormones do not control the estrous cycle. Removal of the ovaries disrupts the estrous cycle.
