Hcg? Should I stay on

Hey all, just wondering if I should stay on hcg? I started trt at 36. I got sperm frozen so not sure I need to stay on it per se- I kinda want to get off it due to cost but just wondering if any sides other than decreased ball size? Prolly most worried about libido. Also kinda worried I’ll never be able to produce sperm down road but I guess having it frozen kinda takes that problem out of the air. Should I stay on? I just feel the cost isn’t worth it per se- I can afford it but don’t feel like paying for it. I also don’t know if I want kids honestly: just want to be able to have them if I somehow want them down the road when in a serious relationship.
