These investigations were performed to determine the causes of the reproductive disorders of the sows in a pig farm which was located at the distance 36m away from the detonation spot. The reproductive problems of the sows such as abortion and infertility occurred after consecutive detonation and use of heavy equipments to build 6 piers of the bridge for the expressway between Jinju and Taeieon during the period from July 1997 to October 1998. 1. The management condition of the farm, microorganism in the feed, inbreeding, hematological conditions, and viral agent causing abortion were not proved as the factors of the occurrence of abortion and infertility in the pig farm. 2. Theoretical concussion values according to the average amount of explosive per detonation were 1.16 kine for minimum amount (3.6 kg) and 3.45 kine for maximum amount(12.5 kg) of explosive, and the theoretical sound values were accordingly 92.29 decibel for minimum amount and 101.76 decibel for maximum amount of explosive, respectively, in the case of 36m distance between the detonation spot and pig farm. The frequency of detonation in a day was 7 times with interval of 15 minutes. 3. The occurence of infertility in the farm was 57.3% during the period of construction from July 1997 to August 1998. 4. In comparison of body weight of piglets between the damaged and not damaged farms, growth of piglets at the damaged farm was shown to be delayed over 30 days than those of not-damaged farm. In conclusion, abortion of 40 sows, delivery of whole still births of 22 sows, and infertility of 122 sows in the pig farm were assumed to be caused by the concussion or sound stress after consecutive detonation and use of heavy equipments.

It has been reported that oral kallikrein therapy exerts a favourable effect on sperm motility in asthenozoospermic patients. In order to evaluate the efficacy of kallikrein on asthenozoospermia, a total of 20 subfertile male patients with varicocele, whose sperm counts were less than $40{\times}10^6/ml$ and sperm motility was less than 30%, was subjected to this clinical study (Table 1). They were divided into 2 study groups: 1) Varicocelectomy group consisted of 10 patients with varicocele (grade II-III) who underwent varicocelectomy. 2) Kallikrein group was composed of 10 patients with varicocele (grade I) who were given kallikrein orally 600 KU (kallikrein unit) daily divided 3 times after meal for 3 to 9 months. Semen analyses were repeated twice before the study, once a month during the study and twice after the study. Effective results designate that sperm parameters improved more than 30% from the basical levels after varicocelectomy or kallikrein exposure. Sperm counts increased from $32.5{\times}10^5/ml$ to $45.5{\times}10^6/ml$ after varicocelectomy in 3 patients and sperm motility increased from 25% to 38.5% after varicocelectomy in 3 patients. Pregnancy occurred in 2 patients of 3 responders and 1 patient of 7 non-responders 3 to 6 months after varicocelectomy in Varicocelectomy group. Sperm motility increased from 28% to 40.2% after kallikrein treatment in 3 patients. Pregnancy occurred in 2 patients of the 3 responders in Kallikrein group (Tables 2-3). There were no significant changes in volume and morphology in Varicocelectomy group before after varicocelectomy and no significant changes in volume, counts, and morphology before and after kallikrein exposure. No remarkable side effects were noted with kallikrein treatment.

Pulmonary endometriosis is an uncommon disease, and usually detected by catamenial hemoptysis. Treatment of pulmonary endometriosis may be medical(hormone therapy) or surgical. Since hormone therapy may cause sterility, most of patients who wish to conceive usually choose surgical resection. Although video-assisted thoracic surgery(VATS) has advantage of small scar, reducing postoperative pain and shortening hospital stay, it is not easy to locate the precise lesion and resect whole endometrial tissue not to be remained. 17 years old female with catamenial hemoptysis was treated sucessfully with a partial resection of the lung using VATS, and has been asymptomatic for 7months since the operation.

The pathogenesis of endometriosis is unknown, but retrograde menstruation is widely accepted as an etiology. Refluxed endometrium from endometriosis patients is more prone to implant and invade peritoneum possibly through the action of extracellular proteolysis. This proteolytic action may involve plasminogen activators and the collagenase system. Plasminogen activators (PAs) and matrix metalloproteinases (MMPs) play a critical role in the breakdown of extracellular matrix components and basement membrane in the processes of implantation and tumor invasion. PAs are inhibited by plasminogen activator inhibitor (PAI) and MMPs activity is inhibited by tissue inhibitor of metalloproteinase (TIMP). To test the hypothesis that lower expression of PAI-1 and TIMP-3 in endometrium from women with endometriosis, we investigated their PAI-1 and TIMP-3 expression by quantitative competitive RT PCR in endometrium from women with and without endometriosis. Endometrial tissues were obtained from 14 patients with severe endometriosis and 14 patients without endometriosis. Total RNA was extracted and reverse transcribed into cDNA, and quantitative competitive PCR (QC PCR) was performed to evaluate PAI-1 and TIMP-3 mRNA expression. Endometrium from patients with endometriosis showed decreased expression of PAI-1 and TIMP-3 mRNA compared to endometrium from control in luteal phase (p<0.05). Our results suggest that endometrium from women with endometriosis expresses lower levels of PAI-1 and TIMP-3 than endometrium from normal women. Endometrium from endometriosis patients may be more invasive and prone to peritoneal implantation than control because of higher PA and MMP enzymatic activity. Thus, increased proteolytic activity may be one of the reasons for the invasive properties of the endometrium resulting in the development of endometriosis.

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%.

Azoospermia factor(AZFa, b, and c) regions have been focused on their involvement in the spermatogenic process by frequent observation of microdeletion in male infertility. Among the azoospermia factors, RBMY1, CDY1, and VCY2 genes are strongly associated with the male germinal cell differentiation and development in testis. Using RT-PCR approach, expression patterns of RBMY1, CDY1, and VCY2 genes are examined in testicular biopsy specimens from 42 Korean azoospermic patients. No expression of RBMY1, CDY1, and VCY2 genes appeared as 34%, 66%, and 27% of the male infertility, respectively. Patients who had no expression of RBMY1 and VCY2 genes also showed negative expression of the CDY1 gene in their testis tissues. All Sertoli cell-only syndrome patients showed no expression of the CDY1 gene. Taken together, the CDY1 gene expression seems to be necessary factor to complete spermatogenesis in Korean population.

Retrograde ejaculation, an infrequent cause of male infertility, may be the sequala of prostate or bladder neck surgery or the result of interruption in the sympathetic innervation, the diagnosis is established by history and examination of urine. Infertile couple artificial insemination homologous(AIH) using retrograde ejaculate recovered from bladder has been successfully acomplished. In this case, ovulation was induced by clomiphene citrate, osmorality and pH of urine was controlled by buffer solution and immediately specimen collection, to improve sperm mobility. We had experienced a successful pregnancy and delivery case by above method. So here reported with brief review of literature.

The testicular volume measured by a Prader orchidometer was compared with sperm count in semen, the levels of serum FSH, LH, testosterone, prolactin, estradiol and progesterone in 59 nonobstructive infertile men. 1. The causes of infertility were primary hypogonadisms in 50 patients (35 unknown, 9 Klinefelter syndromes, 6 varicocels) and secondary hypogonadism in 9 (5 isolated FSH deficiencies, 1 hyperprolactinerriia, 3 pituitary hypogonadisms). 2. Decreased levels of serum FSH (less than 4 mIU/ml) did not correlate with testis volume but increased level of serum FSH (more than 20 mIU/ml) were mostly noted in the testis less than 10ml. 3. Decreased level of serum testosterone (less than 3 ng/ml) were distinguishably noted in the atrophied testis less than 5 ml. 4. There was no correlation between the testicular volume and the levels of serum prolactin, estradiol, and progesterone. Coclusively, testicular volume less than 11 ml suggests poor spermatogenesis, but normal testicular volume dose not nessarily rule out poor spermatogenesis. Function of Leydig cell is relatively well preserved in atrophied testis of 5 to 10 ml comparing with that of seminiferous tubule.

We experienced a 4-month-old boy presenting with fever and painful scrotal swelling. Diagnostic work-up showed the presence of urinary tract infection and concurrent acute epididymitis. On the voiding cystourethrography, vesicoureteral reflux and urinary reflux through the ejaculatory duct and the seminal vesicle were detected without obvious urethral obstruction. In general, urinary reflux into the seminal vesicle can take place with obstructive lesions of the urethra and may cause epididymitis in infants. We report a case of urinary reflux without urethral obstruction with a brief review of related literatures.
