Older Age and Low Testosterone Levels Are Independently Associated With Kidney Stone Prevalence in Men: Results From a Large Cross-Sectional Study

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.

Dutasteride treatment may decrease sperm concentration, but levels remain above WHO recommendations and recover after discontinuation. The study has limitations, including small sample size and lack of pre-treatment sperm data, and does not assess other fertility factors.

A 25-year-old male experienced increased testosterone and estradiol levels after starting finasteride for hair loss, leading his doctor to suggest a testicular ultrasound as a precaution. The user questions the necessity of the ultrasound, considering it potentially excessive, while others suggest it could be a useful precaution to rule out any issues.

Dutasteride may reduce bone mineral density, but there's no increased risk of osteoporosis or fractures compared to finasteride. Users suggest resistance training to counter potential bone effects.

Creatine may increase DHT levels, potentially affecting hair loss, but evidence is mostly anecdotal. A study to explore this was withdrawn due to funding issues.

Dutasteride may affect testosterone levels, leading to high ferritin and iron levels, which can cause hair loss. High ferritin might be linked to past heavy drinking or hemochromatosis.
