The researchers reported that finasteride treatment in male rats may lead to changes in antioxidant enzyme activity in their offspring's epididymis, potentially affecting sperm maturation.
This study found that finasteride altered androgen receptor expression in the rat epididymis without affecting the morphology of epididymal epithelium, suggesting a change in hormonal status.
This article summarizes findings on the role of androgens and estrogens in male reproductive tissues across species, highlighting the roles of hormone metabolism, receptor distribution, and stress-induced changes.
Finasteride's potential side effects, especially sexual dysfunction, are discussed, with emphasis on hormonal balance between testosterone and estradiol. Users share experiences with finasteride, minoxidil, and dutasteride, highlighting the variability in side effects and the influence of mindset and lifestyle.
Quitting vaping significantly reduced hair loss for a user who was a heavy vaper and also taking finasteride. Some participants suggest nicotine's vasoconstrictive properties may worsen hair loss, while others share personal anecdotes of hair improvement after quitting smoking or vaping.
Finasteride and Dutasteride do not cause depression or "Post Finasteride Syndrome," with concerns often linked to the nocebo effect and preexisting mental health issues. The EU is unlikely to ban these drugs, but access may become more restricted due to ongoing debates.
Creatine may counteract minoxidil's hair growth effects by closing potassium ATP channels, potentially leading to hair loss in predisposed individuals. Despite anecdotal reports, there is no conclusive evidence linking creatine to hair loss.
Topical Finasteride doesn't directly reduce 5ar enzyme on scalp and has the same mechanism as oral, needing to go through the liver. Users debate the accuracy of this information and discuss various studies and experiences.
