Objective:To investigate the correlation between the partial deletions polymorphism in the AZFc region of Y chromosome and male novel spermatogenic impairment.

Several factors have been proposed for male infertility and spermatogenic failure is confirmed to be a significant one, which typified by idiopathic non-obstructive azoospermia or oligozoospermia.

Experimental study on the effect of Zan Yu Yan Sheng Yin on spermatogenesis disturbance of rats;

To study the influence of BAOSHENG decoction on testis of spermatogenesis dysfunction mice,the models were made and divided into groups,and then the density and the active rate of spermatozoon,the weight of testis,epididymis and mice,the histopathologic slice of testis were tested.
