May not be totally related but I’m 40 and just restarted my system after 2 years of trt. My balls were tiny to say the least.
3 months later of clomid at 50mg a day, my level is 970 produced from my own balls. They are bigger than they were before trt.
But clomid isn’t something in my opinion that you want to stay on. I only did it for fertility. On trt I was shooting blanks. My last test showed 51 million sperm per milliliter at 75 percent motility. Thank God it came back.
If you’re concerned about fertility, I would say stop trt and begin clomid. Once your system is started back, restart trt but also run hcg.
HCG should work though to get them back to normal size.
