Testicular Enzymes Related to Steroid MetabolismAndrogen biosynthesis and metabolism in the testis occur in a well defined cellular and subcellular localization. This paper examines the distribution of various enzymes among different testicular cells, as well as the subcellular localization of some of these enzymes.作者: 撕裂皮肉 時(shí)間: 2025-3-22 12:20
