Cognitive Effects of Testosterone and Finasteride Administration in Older Hypogonadal Men

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 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.

A 30-year-old man experienced significant hair regrowth and improved libido after using finasteride and dutasteride for androgenetic alopecia, with no adverse effects. He plans to reduce dutasteride dosage when trying to conceive and has been using topical minoxidil since 2015.

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.

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.

Finasteride may decrease free testosterone by increasing SHBG, potentially causing side effects like reduced libido and hormonal changes. Some find it effective for hair loss, while others experience negative effects.
