Association of Breast Cancer in Men with Exposure to 5-Alpha Reductase Inhibitors: A RADAR Report

The user is experiencing breast tissue growth from taking dutasteride and minoxidil, and is considering reducing the dosage or stopping the medication. Suggestions include seeing an endocrinologist, using Raloxifene or Arimidex, and considering topical treatments or surgery if necessary.

FCE 28260 (PNU 156765), an under-explored 5α-reductase inhibitor, showcases promising results in research by Giudici et al., outperforming well-known treatments like Finasteride in reducing the conversion of testosterone to DHT. Its superior efficacy, demonstrated through lower IC50 values in both natural and human recombinant enzyme studies, suggests it could offer more effective management of DHT-related conditions. Additionally, its lower molecular weight hints at better potential for topical application, potentially offering advantages in treating conditions such as androgenic alopecia. Despite its potential, it has not advanced in development, possibly due to financial limitations, leaving its therapeutic prospects and side effect profile largely unexplored.

The conversation discusses the fear-mongering around 5AR inhibitors like finasteride for hair loss, with some users arguing about the percentage and severity of side effects. The main point is that while some experience side effects, others believe these are reversible, and the focus should be on informed decision-making rather than spreading fear.

Topical androgen receptor antagonists may not be necessary if 5-AR inhibitors like finasteride or dutasteride effectively reduce DHT levels. Combining a 5-AR inhibitor with a topical androgen antagonist could potentially enhance treatment, but oral use of androgen antagonists is too risky due to severe side effects.

Men discussing hair loss treatments, including bicalutamide, cyproterone acetate, dutasteride, minoxidil, and RU58841. They share experiences and concerns about side effects like infertility, liver health, and feminization.

The user experienced sexual side effects after starting finasteride and later switched to dutasteride, noticing hormonal changes. They are considering using P5P and possibly aromatase inhibitors to manage high prolactin and estradiol levels.
