[Pregnancy after transfer of the gametes into the fallopian tubes]
Abstract:
Three patients with idiopathic sterility were treated by transferring the gametes into uterine tubes. Clomiphene+ citrate stimulation of superovulation was employed. Preovulatory oocytes were obtained via the laparoscopic approach. Two oocytes with capacitated spermatozoa were placed into the tube of patient 1, four cells into one tube of the second patient, and two cells into each tube of the third patient. Pregnancy started in two cases, uterine in one, eventuating in 12-13 weeks in spontaneous abortion, and tubal in the other, eventuating in tubectomy. These data evidence the possibility of transferring gametes into uterine tubes to sterile patients, in whom sterility is not caused bu tubal diseases.
