The presence of a male from the afternoon of pro-oestrus to the following morning resulted in significant increases in anterior pituitary and uterine weights both in female rats on an unrestricted food intake and in underfed females . A significant decrease in pituitary LH content was apparent in the underfed group exposed to males . A trend towards an increased number of ovulations was found in females of both groups subjected to the presence of a male when compared to control animals (12.9 v 12.4 on unrestricted diet and 11.8 v 10.9 on 75% food), but the differences did not reach significance.
