Testosterone Reduces Knee Passive Range of Motion and Expression of Relaxin Receptor Isoforms via 5α-Dihydrotestosterone and Androgen Receptor Binding

Androsterone may help with sexual and affective dysfunction from finasteride by replacing disrupted neurosteroids without increasing androgenic side effects. Controlled testing is needed to confirm its effectiveness and safety.

Bicalutamide blocks androgen receptors, preventing testosterone and DHT from binding, which can help with hair loss but may cause feminization. It is not recommended for those who do not want feminization effects.

Fluridil degrades androgen receptors, which are prevalent in the scalp and other tissues. People with androgenetic alopecia (AGA) may have higher expression of these receptors and 5AR activity in affected scalp areas.

Fluridil was abandoned due to its weak effectiveness and low binding affinity to the androgen receptor, making it less competitive against DHT and testosterone. Users discuss its limited results compared to other treatments like pyrilutamide and RU58841.

Pyrilutamide and RU58841 are androgen receptor antagonists that block receptors without significantly reducing testosterone or DHT levels. Any indirect effect on androgen levels is likely negligible.

The conversation discusses androgen receptor degraders for hair loss, highlighting their potential advantages over traditional AR blockers like RU58841 and pyrilutamide. Concerns about the safety and cost of these treatments are also mentioned.
