Androstanediol glucoronide is a hormone derived from DHT (the hormone inhibited by finasteride). In men affected by the PFS, the level of Androstanediol Glucuronide is not restored to previous finasteride levels. The result of the blood test hormone in these patients is generally below the scale or a very low result. It’s unnatural for adult men to have low levels of this molecule. Only individuals who are born with intersex characteristics (hermaphrodites) have low levels of this hormone. It is essentially a masculinizing hormone and may have an effect on sexuality… Women present low levels of Androstanediol glucoronide naturally, since they produce little testosterone. Women who have high levels of this hormone, show reproductive problems (polycystic ovary), excess body hair and a more masculine appearance.
