Although testosterone is the principal sex steroid produced by the testis, estrogen is known to be produced by both Leydig and Sertoli cells during different developmental periods. Additionally, evide...

We have previously demonstrated that cytochrome P450 aromatase (P450arom) protein, an estrogen-synthesizing enzyme, is present and active in germ cells of the adult mouse testis. To establish that P...
Mouse epididymal sperm contain active P450 aromatase which decreases as sperm traverse the epididymis
