Ovulatory function after tubal microsurgical procedures in the rabbit.
Ovulatory function as correlated with the production of corpora lutea was studied in 72 rabbits that were subjected to unilateral tubal microsurgical procedures. Isthmo-isthmic reanastomosis was performed in 11 rabbits, ampullo-isthmic reanastomosis in 10, and ampullo-ampullary reanastomosis in 11. In a second group of 40 animals, 20% to 100% of the isthmic portion (n=20) and 20% to 60% of the ampullary portion (n=20) were resected with reanastomosis. After natural copulation of the animals, without administration of gonadotropin, the numbers of corpora lutea on the operated and control side were counted. A slight but nonsignificant overall reduction in corpora lutea on the anastomosed side was observed. This showed no correlation to amount of tubal resection or proximity of the anastomosis to the ovary.
