멸종 위기에 처한 침팬지에서 연중번식주기와 무월경, 번식주기, 임신진단을 포함한 번식형태를 관찰하기 위하여 형광항체 분석법을 사용하여 에스트라디올, 프로게스테론, 테스토스테론 호르몬 대사산물과 인간융모성 성선자극호르몬을 측정하였다. 본 연구결과, 침팬지의 번식능력은 연령이 번식에 중요한 영향을 주는 인자가 아니며, 개체별 번식능력의 차이, 산과질환의 유무, 배우자와 합사한 조건에서 나타나는 성적행동의 차이 같은 여러 가지 요인이 복합적으로 작용한다는 것
To monitor the reproductive patterns of endangered common chimpanzee including annual reproductive cycle, amenorrhea, breeding season, and pregnancy diagnosis, Time-Resolved Fluorescence Immuno Assay (TR-FIA) was used to trace MRH (estradiol, progesterone, testosterone) and human chorionic gonadotropin (HCG). In result of this research, age was not the important factor in determining the reproduction capability in common chimpanzee; it was rather greatly influenced by the combination of various factors such as individual's fertilizing ability, presence of obstetrical diseases, the pattern of mating behavior, and the mental communication under the introduction of a mating partner. This research will play an important role in operating conservation project for common chimpanzees and can be extended also for shedding new light on understanding human menopause and obstetrical diseases.
