It's androstenedione at very high levels that's produced in female hyenas that creates this enlargement of their genitalia. So if you want to read up on androstenedione. Androstenedione is made into testosterone through this enzyme 17-beta-hydroxy steroid dehydrogenase it's a complicated pathway to pronounce. It's a fairly straightforward pathway biochemically. You may recall during the 90's and 2000's there were a lot of performance enhancing drug scandals, in particular in Major League Baseball.
