Genes on the long arm of Y chromosome, particularly interval 6, are believed to playa critical role in human spermatogenesis. The objective of this study was to validate a sequenced-tagged site(STS)-mapping strategy for the detection of Yq microdeletion and to use this method to determine the proportion of men with Yq microdeletions in idiopathic, obstructive, nonobstructive azoospermia, severe OATS and in normal males. We analyzed three STS markers mapped to interval 6 within long arm of the Y chromosome from 106 nonobstructive, 30 obstructive azoospermia, 15 severe OATS patients, and normal 42 males in Korean men. By PCR, we tested leukocyte DNA, for the presences of STS markers(DAZ, sY129 and sY134) and SRY gene as internal control. And PCR results were confirmed by Southern hybridization, and were investigated by SSCP analysis for DAZ gene mutation. None of 42 normal males and 30 obstructive azoospermia had microdeletions, Of the 15 severe OATS typed with DAZ, sY129 and sY134, 3(20.0%) patients failed to amplify 1 or more STS markers, and of the 106 nonobstructive azoospermia typed with DAZ, sY129 and sY134, 12(11.3%) patients failed to amplify 1 or more STS markers. From these results, high prevalence(12.4%) of Yq deletion(DAZ, sY129, sY134) in men with nonobstructive idopathic azoospermia and severe OATS were observed in Korean infertility patients. To avoid the infertile offspring by assisted reproductive technique using ICSI or ROSI, genetic diagnosis will be needed in IVF-ET program.

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%.

Objective: To evaluate the ability of serum anti-M$\ddot{u}$llerian hormone (AMH), FSH, and age to clinically predict ovarian response to controlled ovarian hyperstimulation (COH) in IVF patients with endometriosis. Methods: We evaluated 91 COH cycles, including 43 cycles with endometriosis (group I) and 48 cycles with male factor infertility (group II) from January to December, 2010. Patients were classified into study groups based on their surgical history of endometriosis-group Ia (without surgical history, n=16), group Ib (with a surgical history, n=27). Results: The mean age was not significantly different between group I and group II. However, AMH and FSH were significantly different between group I and group II ($1.9{\pm}1.9$ ng/mL vs. $4.1{\pm}2.9$ ng/mL, $p$ <0.01; $13.1{\pm}7.2$ mIU/mL vs. $8.6{\pm}3.3$ mIU/mL, $p$ <0.01). Furthermore, the number of retrieved oocytes and the number of matured oocytes were significantly lower in group I than in group II. In group II, AMH and FSH as well as age were significant predictors of retrieved oocytes on univariate analysis. Only the serum AMH level was a significant predictor of poor ovarian response in women with endometriosis. Conclusion: Serum AMH may be a better predictor of the ovarian response of COH in patients with endometriosis than basal FSH or age. AMH level can be considered a useful clinical predictor of poor ovarian response in endometriosis patients.

Objective: This study was performed to evaluate the accuracy of hysterosalpingography (HSG) for evaluating female infertility patients by comparison with hysteroscopic and laparoscopic examination. Methods and Material: Total 219 infertile patients were retrospectively analyzed between January 1, 2002 and December 31, 2003. Ninety seven patients (44.3%) were primary infertility, 122 patients (55.7%) were secondary infertility. We performed hysteroscopic and laparoscopic examination on next cycle when HSG revealed any abnormal finding, and 3~6 cycles later if HSG was normal. Results: The accuracy of HSG was 65.2% compared with hysteroscopic examination (sensitivity 88.4%, specificity 46.4%, false positive rate 53.6%, false negative rate 11.6%). The most common abnormal finding of hysteroscopy was uterine synechia (67.4%) followed by endometrial polyp, uterine anomaly (e.g. uterine septum), endometrial hyperplasia. Compared with laparoscopic examination, the accuracy of HSG was 76.9% (sensitivity 98.9%, specificity 70.6%, +LR 3.36, -LR 0.02). The positive predictive value of normal patent tube was excellent (99.6%) but that of proximal tubal blockage was only 46.7%. The unilateral tubal obstruction of HSG was poor accuracy (+LR 3.85 -LR 0.68) and 70% of those was patent by laparoscopic examination. Laparoscopic examination also revealed that 53% of patients had peritubal adhesion and 37% of patients has additional pelvic findings, especially endometriosis. Among the patients had normal HSG, 53.5% patients with normal ultrasonography was diagnosed endometriosis (25.6% of them had endometriosis stage I-II). Conclusion: Normal HSG shows a high negative predictive value. Nevertheless, the incidence of associated pelvic disease in the normal HSG group is high enough to warrant diagnostic laparoscopy if nonsurgical treatment is unsuccessful. Because HSG has poor accuracy in predicting distal tubal blockage and peritubal adhesion, and poor positive predictive value of proximal tubal blockage, laparoscopic examination could be considered in abnormal HSG group.

Objective: We inversigated Small Heterodimer Partner (SHP) gene mutation in Korean Polycystic Ovarian Syndrome (PCOS) patients. SHP protein regulates the activity of nuclear receptors which regulate the cellular development and differentiation. Recently, the mutation of SHP gene was found in the obesity and diabetes patients in Japanese group, and suggested that its mutation may involved in pathogenic mechanism of PCOS. Methods: This study was performed in 20 PCOS patients and 20 normal women. The DNAs were extracted from the peripheral bloods, and amplified at each exon (1 and 2) of SHP gene by PCR method. Subsequently, each PCR product was digested with the restriction enzyme indicated below for studying restriction fragment length polymorphism (RFLP). After enzyme digestion, the results of RFLP were compared PCOS patients with control women to find any sequence variation. Results: We examined 9 regions of exon 1 with Msp I, Pvu II, Dde I and 3 regions of exon 2 with Pst I, Dde I. There is no heterozygous or homozygous mutation in patients and control women at these restriction sites. Conclusion: The genetic analysis at our restriction sites in the SHP gene did not show any genetic variation in Korean PCOS patients. Our PCR-RFLP analysis was not covered the entire SHP gene (68 bp/1,006 bp), we need to further analysis of the entire SHP gene.

Micromanipulation procedures have been used to improve fertilization rates in patients with male factor or with unexplained infertility. Partial zona disseetion(PZD), a method using mechanical force to open the zona pellucida increase the chances of fertilization. The purpose of this study is to increase rates of fertilization and pregnacy in the ART program by using PZD. The influence of PZD on the fertilization rate was investigated in 57 couples with semen defects, antisperm antibodies(ASA), or unknown factors. PZD directly performed in 35 couples with a history of fertilization failure in previous cycle (Group 1), and PZD applied in 22 couples with the failure of initial fertilization in the same cycle (Group 2). The fertilization rates of the male facor, ASA positive factor and unknown factor in Group 1 were 37.6%, 20.0% and 59.2%, respectively. The rates of fertilization of male factor, ASA positive factor and unknown factor in Group 2 were 34.8%, 20.0% and 26.5%, respectively. The incidences of polyspermy in Group 1 and Group 2 were 5.9% and 9.0%, respectively. Among 35 patients of Group 1, one patient was pregnant and successfully delivered, whereas 1 of 22 patients of Group 2 became pregnant, but aborted at 7 weeks.
