This study was presented of the 1,872 cases of infertile couples who visited and examined at the sterility clinic of Department of Obstetrics & Gynecology, Seoul National University Hospital from Sept., 1980 to Dec., 1983. Age, duration of infertility, past medical history, and other general factors were analyzed, and the factors responsible for infertility were classified and discussed. Mode of treatment, outcome of pregnancy, pregnancy rate responsible for each factor were also presented. The results were as follows: 1) The infertility was primary in 1,128, or 60.3% and secondary in 744, or 39.7%. 2) The age between 26 and 30 years of age comprised about one half of the total patients. 3) The duration of infertility between 1 and 4 years comprised about three quarters of the total patients, and the mean duration was 3.8 years. 4) The most common medical history in primary infertility was tuberculous disease, and that in secondary infertility was history of previous laparotomy. 5) About two thirds of antecedent pregnancies were abortion. 6) The major etiologic factor of infertility were male factor in 12.3%, tubal factor in 38.8%, ovulatory failure in 25.4%, uterine factor in 8.8%, cervical factor in 5.2%, peritoneal factor in 9.5%, and no demonstrable cause in 11.3%. 7) The types of male factor were azoospermia in 61.6%, oligospermia in 25.8%, low motility in 11.6%, and other abnormality in 1.0%. 8) The types of ovulatory failure were ovarian failure in 7.4%, hypothalamo-pituitary failure in 8.1 %, hypothalamo-pituitary dysfunction (including Polycystic ovarian syndrome) in 30.2%, and hyperprolactinemia in 22.4%. 9) The types of uterine factor were endometrial tuberculosis in 27.5%, uterine synechia in 33.8%, uterine anomaly in 19.7%, myoma and polyp in 9.1 %, and luteal phase defect in 9.9%. 10) The types of peritoneal factor were pelvic adhesion in 80.9% and endometriosis in 19.6%. 11) Surgeries were done in 408 patients, and they were salpingolysis, lysis of extraadnexal adhesion, salpingostomy, fimbrioplasty, ovarian wedge resection for polycystic ovarian disease, tubo-tubal anastomosis, and tubo-uterine implantation in orders. 12) 243 pregnancies were achieved during the infertility work-up, of which livebirth was 46.5%, ectopic pregnancy was 7.4%, spontaneous abortion was 7.8%, and on-going pregnancy or lost to follow-up was 36.2%. 13) Pregnancy rates in various factors were male factor in 18.7%, ovulatory factor in 31.7%, tubal factor in 24.2%, uterine factor in 34.6%, cervical factor in 19.0%, peritoneal factor in 29.0%, combined factors in 10.5%, and unexplained infertility in 37.1%. Pregnancy rate in whole patients was 25.2%.

In this study, newly-developed slim electronic panel cooler with aluminum PF condenser and evaporator was tested and the results are compared with imported panel cooler with fin-tube heat exchangers. The PF heat exchangers significantly (approximately 45%) reduced the refrigerant charge. The air-side pressure drop was also reduced, which resulted in the reduction of the sound level of the panel cooler. The effect of the condenser size was also investigated.

Follicle monitoring in the normal and clomiphene·stimulated cycles were analyzed in the Seoul IVF and ET (In vitro fertilization and embryo transfer) program. Ovarian follicular diameters were measured by the real·time sector scanner and plasma estradiol levels were assayed by radioimmunoassay methods during periovulatory period. The maximum follicular sizes of the clomiphene-stimulated and normal cycles were 21.1+-3.4mm and 19.2+-0.8mm, respectively. The peak levels of plasma estradiol in the clomiphene-stimulated and normal cycles were 10538+-553.6ng/ml and 298.3+-39.6pg/ml, respectively. Daily growth rate of the follicular diameters of the clomiphene-stimulated and normal cycles were 2.1mm and 1.9mm, respectively. Mean follicular number of the clomiphene-simulated and normal cycles were 2.28+-1.12 and 1.12+-0.21, respectively. There was a good statistical correlation between the mean follicular diameters and the plasma estradiol levels in the normal ovulatory and c1omiphene-stimulated ovulatory menstrual cycles (p<0.05). Our data revealad that the mean follicular diameter and the plasma estradiol level prior to HCG administration in IVF and program should reach at the level of 17.8+-3.0mm and 949.4+-487.1 pg/ml, respectively.

The Radionuclide test (RN test) using radioactively labelled human albumin microspheres was developed recently to evaluate the patency and functional capacity of the fallopian tubes. 57 infertile women underwent this procedure as a part of their infertility work up. The results of the radionuclide evaluation were compared with those of the hysterosalpingography (HSG) and further the surgical findings of the laparoscopy and laparotomy. In 64.9%(37/57) of the cases, there was complete agreement between radionuclide test (RN test), hysterosalpingography(HSG) and surgical findings. In comparison with surgical findings, RN test showed a complete agreement rate of 89.4%(51/57), a partial agreement rate of 5.3%(3/57) and no agreement rate of 5.3%(3/57), respectively. Likewise, HSG revealed a complete agreement rate of 80.7%(46/57), a partial agreement rate of 10.5%(6/57) and no agreement 8.8%(5/57), respectively. It would appear that as opposed to the traditional HSG, RN test may give a better understanding of the functional capacity of the tube and may prove a useful method before and after tubal surgery.

This study was undertaken to demonstrate the relationship between oligomenorrhea/amenorrhea and minor mullerian anomalies. Hysterosalpingograms were taken in total 139 patients including 62 infertile patients with normal menstrual intrerval, 47 infertile patients with oligomenorrhea or amenorrhea and 30 tubal reanastomosis candidates with normal menstrual interval. The results were summarized as follows: 1. In unselected infertile patients, the occurrence rate of minor mullerian anomalies was 38%. 2. The occurrence rate of oligomenorrhea/amenorrhea in infertile patients with minor mullerian anomaly was significantly higher than that of infertile patients with normal uterus and the reverse was the ( ) result. 3. There was no significant difference in the occurrence rate of minor mullerian anomalies between infertile patients and tubal reanastomosis candidates with normal menstrual interval. 4. There was no immediate relationship between the degree of fundal anomaly and the duration of the menstrual intervals and/or the duration of the oligomenorrhea or amenorrhea.
