Gonadotropic Regulation of 5α-Reductase Activity in the Interstitial Cells and Whole Testis Homogenand interstitial cells from rats of various ages. 3α-DIOL concentrations in seminiferous tubules were found to be elevated between 25–35 days of age, at which time testosterone levels were minimal (9). Following the intravenous injection of .H-progesterone and .H-androstenedione into immature rats, r

Synthesis of Estradiol -17β by Sertoli Cells in Culture: Stimulation by FSH and Dibutyryl Cyclic AMP secretion. This was associated with histologic evidence of marked stimulation of the Leydig cells, interference with normal spermatogenesis, and appearance of “degenerative” changes in the Sertoli cells.

Comparison of Steroid Metabolism in Testicular Compartments of Human and Rat Testesticular steroid sulfatase with pregnenolone sulfate exhibiting the lowest K.. Further studies on the steroid sulfatase activity of homogenates or minces of testicular tissues from patients indicated that sulfatase activity was greater in isolated seminiferous tubules than in intact testicular tissue

Concentration of Steroid Hormones and Androgen Binding Protein (ABP) in Rabbit Efferent Duct Fluidd concentrations in rabbit EDF. It was hoped that steroid assays in conjunction with ABP measurements in the same samples would answer the following questions: (a) What is the steroid composition of the fluid bathing the testicular sperm? (b) Is there a relationship between the concentration of andr
