In our previous study, a novel human testis-specific gene, SPATA12, was identified using the digital differential display program. In the current study, both SPATA12 mRNA and protein levels in the developmental stage of the testis were dete...
Abnormal morphology of spermatozoa in cytochrome P450 17alpha-hydroxylase/17, 20-lyase (CYP17) deficient mice [0.03%]
胞嘧啶P450 17α-羟化酶/17,20-裂解酶（CYP17）缺乏型小鼠精子形态异常
