[Functional aspects of healing in microsurgical tubal anastomosis--experimental studies of the rabbit fallopian tube].

Ovarian function and fertility was studied in 46 female New Zealand White rabbits after isthmic-isthmic reanastomosis of the oviduct. Postoperative ovarian function was slightly suppressed and returned to normal after two month. No significant differences were found between the control side and the side of anastomosis. Fertility was reduced directly after surgery on the side of anastomosis as well as on the control side. On the side of reanastomosis a continuous increase of tubal function occurred up to two month after surgery. At this time tubal function was reduced to 30%, the nidation index was about 0.6. Tubal function of the untreated oviduct was nearly normal (nidation index 0.8) two weeks after surgery.
