Ovulatory function after microsurgical reversal of sterilization in the rabbit

Twelve does were subjected to induction of ovulation and the ovulation sites were counted in each ovary after laparotomy and a section in the isthmus of each left tube was performed, followed by immediate microsurgical end-to-end anastomosis. All the right sides were subjected to sterilization at the isthmical portion of the tube. After three weeks rest, the animals underwent induction of ovulation, corpora lutea were counted and at this stage, reversibility of sterilization was carried out in the right tube. Three weeks later ovulation was again induced and the animals were killed. After overall evaluation and comparison of the results it can be affirmed that neither fine microsurgery or sterilization, nor refertilization in the isthmical part of the Fallopian tube interferes with the ovarian function.
