Testosterone Replacement in the Setting of Finasteride Therapy: A Therapeutic Dilemma

An 18-year-old is considering testosterone replacement therapy with finasteride or dutasteride for hair loss but worries about side effects. Users recommend alternatives like minoxidil, RU58841, and consulting a doctor.

A 29-year-old male on 1 mg Finasteride for 3 months has experienced a significant increase in testosterone and estradiol levels, with no major side effects except slightly oilier skin and increased emotional sensitivity. The user is concerned about these hormonal changes and seeks advice, as their general practitioner is not knowledgeable about the issue.

A 23-year-old male experienced an increase in testosterone levels after taking 1 mg of finasteride daily for six months, with no significant side effects reported. Users discussed how finasteride inhibits DHT, leading to increased testosterone, and debated the psychological versus physiological effects of the medication.

The user experienced erectile dysfunction from oral finasteride and is considering alternatives like topical high-dose finasteride, RU58841, topical Latanoprost, and oral Minoxidil. Blood tests showed changes in testosterone and DHT levels, and the endocrinologist advised stopping finasteride.

Dutasteride is recommended for men on testosterone replacement therapy (TRT) with DHT-sensitive hair, as it does not interfere with TRT's anabolic effects and may improve libido and aging male symptoms. Users report varying experiences with libido when switching from finasteride to dutasteride, with some noticing improvements and others experiencing fluctuations.

The conversation discusses concerns about starting finasteride with low testosterone levels, with one person suggesting finasteride might increase testosterone and decrease DHT, and another advising to pay attention to thyroid-stimulating hormone (TSH) levels.
