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.

To decrease the cost of determining estrogens by the High Estrotex (Mochida Pharmaceutica, Japan) method, the authors have modified it, thus reducing the usage of expensive reagents four times. The modified method was applied to evaluate estrogens in 27 infertile patients when stimulating superovulation. The findings were in agreement with the results obtained by foreign special clinics engaged in treating infertility with extracorporeal fertilization followed by embryonal transfer. The pregnancy rate in the females was 15% on an embryonal transfer basis. The modified High-Estrotex method is easy-to-use, rapid, and cost-effective in the measurement of daily urinary estrogen levels. It may be employed both in extracorporeal fertilization and embryonal transfer and in cases which require daily multiple and reliable evaluation of an ovarian response to ovulation inducers.

During October 1987 to June 1989, 609 infertile couples have been treated using in vitro fertilization and embryo transfer (IVF-ET). Of 78 conceptions (15.7% of transferred embryos), 6 (7.7%) pregnancies were ectopic (5 tubal and 1 ovarian). After diagnosis of ectopic pregnancy all the patients were operated; the ovary was resected in 1 patients and tubectomies were done in 5 patients (laparoscopically in 1). All the diagnoses were confirmed histologically. Since prevention of ectopic pregnancy in IVF-ET is not reliable, the patients enrolled for IVF-ET should be considered to be at risk and closely followed up.

Menstrual cycles of 274 women have been analyzed in order to decide on possibility of follow-up of follicular growth and development using echography and retrieval of preovulatory oocytes using sonographically guided transvaginal access during in vitro fertilization and embryo transfer (IVF-ET). Transvaginal echography proved to be a very efficient tool in monitoring follicle growth during an IVF-ET program and outpatient oocyte retrieval with a minimal injury.
