Hi Fernando,
Thank you and thank Nelson for this! And, for the videos, the credit goes to Dave "Mad Max" Bourlet (btw, we are now on Jay Cutler's channel/website) For my part, I am more than happy to help if I can.
I do not see how an AI would lead to osteoporosis in a typical male. If one were not replacing or have enough T then, even then, I find it hard to see how an AI might contribute to osteoporosis because one would already have low T and by extension low E, so an AI would either not be reducing E by much or boosting T by blocking its conversion to E. If a male has enough T and is doing just about anything that is weight bearing, he should be preventing osteoporosis. Doctors tend to focus on estrogen, particularly with women, when treating or discussing osteoporosis, but T helps prevent it as well.
