I’ve Read that DHT is Critical for Numerous As Yet Unknown Functions of the Male Body

I’ve been on Propecia for about 5 years and am concerned about research showing up online, especially about the drug crossing the blood-brain barrier.

According to what I’ve read, medical research shows DHT and 5AR Type-II are absolutely critical for male libido (sex drive), maintenance of proper genital tissue structures/size/function,
seminal fluid production, keeping Estrogen/Estradiol levels in check, mental clarity/function (via assisting the conversion of various neurotransmitters/neurosteroids in the brain), and
numerous other important and as-of-yet unknown functions in the male body.

Do you feel this is all hogwash, or is the hair loss community in for a big change of opinion about the wonder drug Propecia?

Propecia (finasteride 1mg) does not block 100% of DHT. The effectiveness ranges between 60-80% of DHT blocked, which means that DHT is still around and working in the various functions you outlined. I am sure that there are many things we do not know about DHT, but we are using Propecia for what we do know. I can not give you an all clear on side effects on anything that I don’t know. If you don’t trust the FDA’s clearance, that is your prerogative. I’ve had many patients on Propecia for over 10 years now without negative issues and I can only tell you what I’ve witnessed or experienced myself.
