Hi all.....About a year ago, my testicles lost size inexplicably. I'm 38 and never had sexual issues previously. This loss of size occurred about 3 months after a bout of mono. I also have been treated for hypothyroidism for about 7 years with synthroid. During the first several months of facing this, doctors (uro's) were generally unhelpful. A couple said I was fine. One recommended T which I was apprehensive to start because I'm still young and want to preserve fertility. At the time, my total T was about 500. An ultrasound did not find any vascular issues. Cancer was ruled out via the ultrasound and blood work. LH and FSH were about 1.8 each so I assumed I was secondary but I could not find a good doc until about 7 months after onset. Currently, I have a good hormone doc who tested me on clomid for a few months. Clomid bumped my total T from the mid 400s to the low 600s so I assumed that was confirmation of secondary hypo. About 4 weeks ago, I started hcg shots at 500 IUs 3x a week. The T has come up more to about 700. However, the testicles show no sign of bouncing back yet. Is this a sperm production issue? Will it take longer given the time I was untreated (about 8 months)? I've heard that sperm production takes 3 months to get back online. Or do I need a higher dosing of HCG? Or am I looking at other issues? My doc suggested that my adrenals may be sluggish too. Plus my ferritin is 15. Sorry to be rambling. Any help would be appreciated. Thanks guys.
