Translocation of the testicular estradiol receptor is not an obligatory step in the gonadotropin-induced inhibition of C17-20-lyase.

abstract：:This study was undertaken to identify uterine insulin-like growth factor-I (IGF-I) receptors and examine the regulation of these receptors throughout the estrous cycle and after 17 beta-estradiol (E2) administration to immature rats. We have demonstrated type I IGF receptors in crude uterine membranes by binding and c...

Uterine endometrium depends on extrinsic sex steroid input and hence likely has mechanisms that enable adaptation to hormonal variation. Emerging evidence suggests that sex steroid bioavailability in the endometrium is d...
