Objective: Hypogonadotropic hypogonadism (HH) is an uncommon cause of male infertility. We investigated the outcome of gonadotropin therapy for restoring fertility and pregnancy outcomes in patients with HH. Methods: Medical charts of 10 infertile male patients with HH treated with gonadotropin were reviewed. Initial testicular volume were estimated. Semen analysis parameters (semen volume, sperm counts, motility), serum leutenizing hormone (LH), follicle stimulating hormone (FSH), total testosterone were determined before and after human chorionic gonadotropin/human menopausal gonadotropin (hCG/hMG) treatment. Differences were analyzed statistically. Results: Of 10 patients, 7 (70%) succeed at pregnancy (nature pregnancy in 4). Semen analysis parameters, serum FSH, and testosterone were increased significantly after treatment. The population was stratified according to initial testicular volume into a small testis subset (testicular volume less than 10 cc in 4) and a large testis subset (testicular volume 10 cc or greater in 6). Semen analysis parameters and serum testosterone were increased significantly after treatment in large testis subset. Conclusion: Infertile men with HH initiate and maintain spermatogenesis with gonadotropin (hCG/hMG alone or combined) therapy, thus gonadotropin therapy is good choice in infertile men with HH.

수정란 이식의 효율 증진을 위해서는 수태율의 증진 성공적 분만과 송아지 육성에 있다. 수태율의 증진을 위해서는 사양관리가 양호하고 번식기능이 좋은 수란우의 선발, 임신에 적합한 양질의 수정란, 수란우와 수정란의 동기화 정도와 이식 시술자의 기술력 등이 잘 조화를 이루는 것이 절대적으로 필요하다. 적절한 수란우의 선발과 양질의 수정란을 수정란 이식에 적용하는 것은 수정란 이식의 산업화를 더욱더 촉진할 것으로 생각된다. (중략)

Pure voice characteristics of sow were analyzed to predict parturition time. These were analyzed by using oscilloscope and Sound Forge and the results showed that the voice frequency and amplitude of sow were in the range of 30∼2,500Hz and -35∼-75dB. According to the sound analysis results, the frequencies of sound appearance from farrowing sow in the farrowing pen for three days prior to delivery day and eight hours of prior to delivery day and eight hours of prior to time were around 85% and 46%, respectively of the total appearance during eight days to delivery. Forecasting of delivery time of farrowing sow using the number of sound occurrences showed a promising result such that those have been increased whenever the delivery time was approached. The forecasting success rates were 100% for both of one day and six hours prior to the actual delivery.

Pure voice characteristics of sow were analyzed to predict parturition time. These were analyzed by using oscilloscope and Sound Forge and the results showed that the voice frequency and amplitude of sow were in the range of 30~2,500Hz and -35~-75dB. According to the sound analysis results, the frequencies of sound appearance from farrowing sow in the farrowing pen for three days prior to delivery day and eight hours of prior to time were around 85% and 46%, respectively of the total appearance during eight days to delivery.

Endometrial biopsy in the horse is an important technique for maintaining breeding soundness by detecting changes related with reduced fertility and monitoring response to specific uterine therapy. A 13-year-old thoroughbred mare had been in trouble with repeated breeding for getting pregnant before the sample of endometrial biopsy was offered to investigate the possibility of pregnancy in the future. Based on the tissue sections examined, the prognosis for this mare to conceive and successfully carry a foal to term was estimated to be 10 to 50%.

A female Saanen goat was pregnated by a Markhor (Capra falconeri) and three Himalayan tahrs (Hemitragus jemlahicus) were mismated by a conspecific male at Seoul zoo. Cross-breeding whether intentional or unintentional is considered opposite to the primary rule of species conservation. The Markhor, imported in October, 2002, having the number of chromosomes (2n = 60) same as domestic goats accidently mated with a Saanen goat. The mating time was back-calculated on the basis of zookeepers' record. The Saanen and three Himalayan tahrs (2n = 48) were successfully aborted by intramuscularly injecting 15mg $PFG_2{\alpha}$ (dinoprost tromethamine).

정관 복원수술이란 정관의 폐쇄 부위를 제거한 다음 다시 이어 정자의 수송로를 열어주는 역정관수술이다. 배우자의 임신을 위해 하는 이 복원수술의 성공률은 55%정도라고 한다. 정관의 굵기는 2~3mm이나 내경은 0.5~1mm정도로 가늘어 봉합시술엔 정교한 테크닉이 요구된다. 요즘엔 레이저를 이용한 용접방법과 섬유성 아교로 정관을 붙여주는 방법까지 등장했다.
