Hair vs. Sex & More: The Finasteride Decision – Dr. O Helps You Understand What’s Right For You

The discussion opens with the finasteride decision for men using testosterone or stronger anabolic androgens. The clinician says DHT blockers can help with hair, yet a small fraction of users report serious problems. He describes a syndrome reported after finasteride that can include libido loss and erectile dysfunction. Rather than dismissing concerns, he frames the choice as a personal tradeoff that requires clear informed consent. He emphasizes that the goal is not fear, but understanding of potential outcomes before starting therapy. He also explains that DHT has important functions in the penis, scrotum, and prostate related tissues. This sets the stage for why blocking DHT may change more than scalp hair alone.

He then reviews DHT physiology, explaining that five alpha reductase converts testosterone into DHT irreversibly. He notes that DHT is weak in skeletal muscle, so blocking it rarely harms muscle building directly. However, he explains that many potent steroids are derived from DHT or have DHT like effects in tissues. He warns that these androgens can accelerate male pattern balding, especially in genetically susceptible people. Because of that risk, he says men and women have used DHT blockers for years in performance contexts. He also mentions that DHT blockers may not protect hair when someone uses DHT derived steroids directly. Examples like Proviron, Masteron, and Anavar are discussed as compounds where conversion blocking may fail.

The conversation then turns to side effects and long term health signals that deserve careful monitoring. He cites research suggesting possible associations with fatty liver disease, insulin resistance, and kidney disease. He adds that many men mainly fear central nervous system effects like concentration changes and mood problems. He also explains that protecting the prostate is controversial, because data on cancer outcomes can be complex. For men who still choose DHT blockers, he recommends lower or less frequent dosing as a practical compromise. He discusses topical options and pairs them with minoxidil strategies for men prioritizing hair preservation. He closes by urging people to track how they feel, not only lab numbers, while coordinating care with clinicians.
