I have read that fertility can be maintained on trt by using hcg. I mentioned this to my doc and he said he was unsure about this. Anyone know if hcg or anything for that matter can maintain fertility on trt? Basically I am trying to decide if its worth it to go on trt or not. Im 23 and my test levels have been steadily declining over the past year and they now sit at 312 with noticeable low test symptoms, but being able to have kids in the future is very important to me, so i dont want to mess that up.
