@amberwaves: Oh, I did indeed discuss it my doctor a year ago when I was just 1 year into HRT. He said that he believes that I responded so well to HRT (developed almost a C cup, fat redistribution & female curves), face changes, less body hair, etc) that he is not surprised about the non-function and zero sperm count...
Like you stated and just about everyone else regarding the HRT subject... everyone and every body responds differently. After reading various testimonials regarding "change" from others on here and elsewhere, it can be a slow and impatient process or it can happen faster and more dramatically.
