摘要
Sperm mature and acquire the capacity for fertilization during their transit through the epididymis, however little isknown of the molecular events that comprise sperm maturation. Recent advances in transgenic mouse technology holdpromise for illumination of this process. Most of the existing infertile, transgenic mouse lines seem to have defects inepithelial structure or sperm transport rather than direct defects in the maturation of sperm. Temporally and spatially re-stricted targeted disruptions of epididymal specific genes should provide great insight into the epididymal contribution tosperm maturation.
