Infertility after TRT - Is Masteron/Proviron better for TRT

In this episode of Ask the Doc, we get a viewer's question about infertility. He was on Testosterone replacement Therapy for 2 years, and then stopped in an attempt to try for a child. His test levels and sperm levels seem normal according to blood levels, so he's confused about what could be wrong.
In the second question, someone wants to know if Masteron will ever be available in the US legally.
