Estrogens Receptors-New Players in Spermatogenesis

The mammalian testis is a complex organ that serves two important functions, synthesis of steroids, with significant amount of estrogenic hormones produced and production of spermatozoa. Estrogen receptors (ERs) are expressed in cells of the testis as well as the epididymal epithelium. We have demonstrated that estrogen receptor expression is higher in reproductive tissues as compared to non-reproductive tissues. In addition to this, western blot analysis showed a signal for estrogen receptor.
