Glossary Steroid 5 Alpha-Reductase 2

enzyme converting testosterone to potent androgen dihydrotestosterone (DHT)

Steroid 5 Alpha-Reductase 2 (also known as 5α-Reductase Type 2 or SRD5A2) is an enzyme that converts testosterone into dihydrotestosterone (DHT), a more potent androgen. This enzyme plays a crucial role in the development of male characteristics and is also implicated in conditions like male pattern baldness and benign prostatic hyperplasia.

research In Vivo Time-Dependent Inhibition of Human Steroid 5a-Reductase by Finasteride

29 citations , January 1996 in “Journal of Pharmaceutical Sciences”

This study developed a theoretical model that suggests finasteride may completely inhibit 5AR type 2, but not sufficiently suppress type 1, leading to only partial reduction of dihydrotestosterone at clinical doses.

community Did anybody use beta sisterol for hair loss? I saw in many articles in the internet that said that beta sisterol blocks dht by inhibiting 5a reductase type 2 enzyme and some reviews of people who said that it worked better than saw palmetto in terms of stoping hair loss and helping prostate.

in Research/Science 9 upvotes 3 years ago

Beta-sitosterol may inhibit 5-alpha reductase type 2 enzyme, potentially reducing DHT levels and promoting hair growth, similar to finasteride but possibly with fewer side effects. Its effectiveness and side effects compared to other treatments like saw palmetto and finasteride remain uncertain due to limited research.

community 2.5 years Minoxidil and HRT, CPA->Lupron +Minox 5%

in Transgender 611 upvotes 1 year ago

The user experienced significant hair regrowth after 2.5 years of using Minoxidil 5% and hormone replacement therapy (HRT) with Lupron, despite initial scalp irritation. Finasteride was ineffective for them.

community Finasteride does deplete important nuero-active steroids

11 upvotes 3 years ago

Finasteride can reduce neuroactive steroids, causing side effects like depression, anxiety, and sexual dysfunction. Some users experience persistent symptoms after stopping finasteride, while others use alternative treatments like topical solutions.

community Feeling the 2nd, perhaps 1st, Dutasteride shed, might shave, might thug it out.

in Progress Pictures 67 upvotes 1 year ago

The user is experiencing increased hair shedding after 6 months of using Dutasteride and oral minoxidil, despite previous regrowth and satisfaction with the results. They are considering shaving their head again and discuss the effectiveness of their treatment routine, which includes Dutasteride, oral minoxidil, and Nizoral, while also addressing concerns about side effects like erectile dysfunction and body composition changes.

community Hormonal Imbalance Theory and the "Trash Hormone"...

2 upvotes 3 years ago

Balancing hormones, particularly testosterone and DHT, may prevent hair loss and slow aging. Treatments include finasteride, dutasteride, zinc, magnesium, collagen, and natural DHT-blocking shampoos.
