Investigation, Treatment, and Monitoring of Late-Onset Hypogonadism in Males: ISA, ISSAM, and EAU Recommendations

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 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 can significantly increase testosterone levels, sometimes more than finasteride, which may be counterproductive for some users. Users report varying experiences with testosterone levels and hair loss management while using these treatments.

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 22-year-old male experienced increased testosterone and estradiol levels after 8 months on finasteride, leading to softer erections and reduced arousal. Suggestions included reducing finasteride dosage, using supplements like L-arginine, L-citrulline, zinc, and possibly tadalafil to improve symptoms.
