BACKGROUND :Rapid development of spermatogonial stem cells is the new hope for assisting reproductive technologies, and the stability of the number and structure of the chromosome cultured in vitro is one of the important factors in usage.

Pem gene is expressed in a time and stage specific manner. Pem transcripts are detectable as early as day 6 in mouse embryonic development, and are abundant in day 7 and 8, but decrease precipitously thereafter. Although Pem transcripts are not detectable in most of adult tissues, they are present in reproductive system. Furthermore, Pem has also shown to be specifically expressed in the proximal cauda and distal corpus regions of the epididymis, the regions where spermatozoa gain forward motility and fertilization competence.

Pem基因的表达具有明显的时间和空间特异性：在鼠胚发育的第6天，即可检测到Pem转录本的表达；第7-8天，Pem表达量达到最高，随后迅速减少；Pem基因在成年组织中一般不表达，但可在生殖组织表达；另外，Pem特异地在附睾近侧尾部和远侧的体部中表达，此处是精子获得运动性和受精能力的地方。

Objective: The hypothesis of this study: the pathogenesis of the puberty polycystic ovary syndrome is the maladjustment of procreation axis named Kidney-TianGui- ChongRen meridians-womb. This disease is the syndrome of the root deficiency and the branch sthenia, In this case, the root is deficiency of kidney energy while the branch is blood stasis and phlegm stasis.
