CREM基因与特发性生精障碍关系的研究

The Research of the Relationship Between the CREM Gene Mutation and the Idiopathic Spermatogenesis Impairment

目的探讨环磷酸腺苷反应元件调节物(CREM)基因与男性不育症中特发性生精障碍的关系。方法收集特发性无精子症和严重少精子症各20例患者的外周血,收集具有正常生育能力志愿者20例外周血作为对照。进行外周血提取DNA、聚合酶链反应(PCR)扩增、单链构象多态性(SSCP),检测特发性生精障碍患者外周血中CREM基因。结果在65%的无精子症和55%严重少精子症患者中检测出CREM基因的变异。结论在人类,CREM基因在精子的发生发育过程中起着至关重要的作用,CREM基因参与人类精子的发生。

Objective：To research the relationship between the cyclic AMP-responsive element modulator（CREM） gene mutation and the idiopathic spermatogenesis impairment in male infertility.Methods：The peripheral bloods were collected from 20 patients with azoospermia and 20 patients with serious oligospermia.The peripheral bloods of 20 volunteers with normal fertility were collected as control group.The CREM gene of patients with the idiopathic spermatogenesis impairment was detected by collecting the DNA of the peripheral blood,PCR amplification and single-strand conformation polymorphism.Results：65% of the patients with azoospermia and 55% of the patients with serious oligospermia had the CREM gene mutation.Conclusion：CREM gene plays an important role in the process of sperm development for humans.CREM gene is involved in human spermatogenesis occurrence.
