7 citations, April 2019 in “The Journal of Steroid Biochemistry and Molecular Biology”

11α-Hydroxyprogesterone is changed into different substances by certain enzymes and may play a role in prostate cancer.

research Role of 5α-Dihydrotestosterone in Testicular Development of Gilthead Seabream Following Finasteride Administration

8 citations, July 2017 in “The Journal of Steroid Biochemistry and Molecular Biology”

DHT affects testicular development and regulates spermatogenesis in some fish.

research Consequences of Steroid-5α-Reductase Deficiency and Inhibition in Vertebrates

21 citations, January 2020 in “General and Comparative Endocrinology”

Lack or blocking of SRD5a, a key component in hormone creation, can lead to conditions like pseudohermaphrodism and affect hair growth, bone mass, muscle strength, and reproductive health. More research is needed on its regulation from fertilization to adulthood.

community Study shows further evidence that finasteride and dutasteride take 12-18 months or more to show significant results. Do NOT give up early

in Finasteride/Dutasteride 247 upvotes 1 year ago

The conversation discusses the effectiveness of finasteride and dutasteride in treating hair loss, emphasizing that significant results often take 12-18 months or more. Dutasteride is generally considered superior, with similar or fewer side effects than finasteride, but patience is required for noticeable improvement.

community Anyone experienced weight gain on dutasteride?

in Finasteride/Dutasteride 6 upvotes 2 years ago

Dutasteride can lead to increased cholesterol and liver fat. The user is reconsidering its use due to high cholesterol and lipid levels despite a healthy lifestyle.

community What About Phytosterol Alternatives - Rice Bran Oil - Natural DHT Blockers

in Research/Science 4 upvotes 6 months ago

The conversation discusses natural DHT blockers like rice bran oil, which may reduce 5α-reductase activity similarly to Minoxidil and Dutasteride. One user argues that finasteride is more reliable and effective than natural alternatives.

community Efficacy of different dutasteride doses vs finasteride

in Research/Science 123 upvotes 1 year ago

Dutasteride doses matter for hair loss treatment and are more effective than finasteride. RU58841 is suggested for better gains, but side effect profiles should be considered.

community A systematic bro-science review of DHT, 5AR, neurosteroids, sexual health and 5AR inhibitors

in Research/Science 37 upvotes 2 years ago

Hair loss treatments, specifically 5AR inhibitors, can impact neurosteroids and sexual health. The effects of topical fin/dut on tissue-specific DHT levels are unclear.
