| Outline of Final Research Achievements |
Polycystic ovary syndrome(PCOS) is the most common etiology of menstrual disorders and hyperandrogenism. At present, the understanding of PCOS has advanced significantl.PCO was induced by a single intraperitoneal injection of Testosteron propinate(TP)(0.1mg,dissolved in sesame oil) in 4-5 days female mice. The mice for 5 weeks after TP adminstration exhibited constantly either Estrus or Diestrus and resulted in anovulatory polycystic ovaries. These ovaries contain multiple large follicles and no corpus luteum. Its morphrogy and ovulatory failure are similar to PCOS of human. These ovaries contain multiple large follicles and no corpus luteum. Its morphrogy and ovulatory failure are similar to PCOS of human. It was subjected to immunohistochemistry of serotonin in those PCO. Expression of serotonin was strongly expressed in the later secondary follicles. It was suggested that excessive serotonin expression in ovarian caused abnormally enhance follicle maturation
