From: Aromatase expression and role of estrogens in male gonad : a review
Aromatase and estrogen receptors (ER) in adult male rat gonad. PS: pachytene spermatocytes, RS: round spermatids, Spz: spermatozoa. Aromatase has been demonstrated in terms of mRNA (RT-PCR), protein (Western blots) and enzyme activity (measurements of estradiol output in culture media) in the various testicular cells. ER : estrogen receptors localisation.
