It maintains the intracellular concentration of biologically active steroid hormones in a wide range of male and female human tissues. It catalyzes the interconversion of testosterone and androstenedione as well as estradiol and estrone through 17-β HSD activities. HSD17B2 also of 20α-HSD activity towards 20α-dihydroprogesterone.
