Follicular phase hormonal profiles during administration of leuprolide for in vitro fertilization.

Hormonal changes induced during short-term administration of leuprolide were evaluated during the follicular phase in 57 patients who completed an IVF cycle. They were compared with those of 14 patients who were placed on long-term suppression. There was an unexpected abnormal increase in serum progesterone during the first week of the cycle in nine of the 57, with no significant change in the fertilization and cleavage rate; however, no pregnancy was achieved in this group. Transient mild elevation of progesterone was also detected in 16 patients with no adverse effect on fertilization and the outcome of the IVF. In the long protocol, the tonic levels of LH, FSH, and progesterone remained low throughout the follicular phase. The total number of pregnancies was higher in the short suppression regimen, but the full-term pregnancy rates were similar in both protocols.

Hysterosalpingography, laparoscopy and hysteroscopy in infertility. A comparative study.

The accuracy and significance of hysterosalpingography (HSG) during an infertility evaluation were assessed by comparing the radiologic findings on HSG to the operative findings during laparoscopy and hysteroscopy. One hundred ninety-three patients underwent a complete infertility evaluation at our center. HSG was performed during the proliferative phase and was followed by laparoscopy and hysteroscopy, when indicated, during the same or next cycle. False-positive findings on HSG were noted in 5.1% of the patients. In 21%, adnexal adhesions and pelvic endometriosis were identified during surgery in spite of normal HSG. HSG is as accurate as laparoscopy in the diagnosis of tubal disease. However, laparoscopy excels HSG in the diagnosis of pelvic pathology. HSG should remain an integral part of the female infertility investigation and must be performed before laparoscopy and hysteroscopy.

Effectiveness of stimulated menstrual cycles and Percoll sperm preparation in intrauterine insemination.

To examine the usefulness of intrauterine insemination in women with various fertility factors, we retrospectively analyzed data from women treated during 1986 and 1987. Ninety-three patients underwent 1-11 cycles of single or double procedures, for a total of 423 inseminations in 263 treatment cycles. Twenty-six patients (28%) conceived, for a 10% total pregnancy rate per cycle, with 58% of the pregnancies resulting from double inseminations per cycle. An average of two treatment cycles was required to achieve pregnancy. Eight pregnancies (31%) occurred in spontaneous cycles, while 18 (69%) occurred in stimulated cycles. While clomiphene citrate therapy was useful in anovulatory patients, it was of no benefit in ovulatory patients being treated with intrauterine insemination. Human menopausal gonadotropin therapy was of benefit in both ovulatory and anovulatory patients when combined with intrauterine insemination. The live birth rate was higher (75%) in spontaneous cycles than in stimulated cycles (44%). Semen preparation was accomplished by sperm washing in 61% of the pregnancies and by Percoll preparation in 39%. The effectiveness of the discontinuous Percoll gradient for semen preparation for insemination was suggested by a pregnancy rate of 9% per cycle. While the mean sperm count in the pregnant group was 44 million, successful pregnancy was accomplished with a double insemination of 880,000 and 1.16 million rapidly progressive sperm in the first and second inseminate, respectively. The data confirm the important role of intrauterine insemination for the treatment of infertility.

Evaluation of the Pipelle curette for endometrial biopsy.

The Pipelle endometrial suction curette was evaluated, and its application and effectiveness were compared to those of the Novak curette for endometrial sampling during the midluteal phase. Fifty women underwent an endometrial biopsy with the Pipelle and Novak curettes. Ninety percent of the women preferred the biopsy with the Pipelle. Histologically, tissue obtained with the Pipelle was satisfactory and similar to that with the Novak. The Pipelle curette appears to be an excellent device for midluteal endometrial biopsy during an infertility evaluation.
