It helped me get nocturnal and morning erections again. I am up to this day taking 50mg before every night. Last time I checked my test levels were in range. I will do another test in 2 weeks after my fast and see where I am at.
If you do not notice a raise in T with Clomid but still a raise in FSH/LH then that may indicate issues with the leydig cells in your testes. I do however not think that PFS typically involves damaged testicles. If you do not notice a raise in T following Clomid use you can look into that further (get blood work, try HCG, etc).
