Urbana, Illinois 61801 The ovaries of 83 crossbred gilts were autotransplanted to the uterus, the intestine, or the body
wall by a two-step process. Gilts with both ovaries transplanted to the uterus or to the body wall
had normal estrous cycles. Unilaterally ovariectomized gilts with the remaining ovary attached
to the intestine did not cycle and developed large ovaries with numerous luteinized follicles. These
data indicate that 1) the normal ovarian-uterine circulation is not mandatory for gilts to exhibit
normal estrous cycles, and 2) feedback from ovaries autotransplanted to the intestine does not
reach the hypothalamus to control gonadotropic output from the anterior pituitary.
