HCG/I want to know gonadotropin injection used to treat fertility naturally by sending signals from pituitary gland to testis for producing more testrone - it do not have side effect and it can also reverse testis shrinkage TRT/Testron Replacement Therapy-But in another hand testrone therapy by putting artificial testrone in body will increase testrone rate but after some time in future it is going to decrease normal testrone because pituitary is going to stop sending to make more testrone hence it going to reduce the sperm rate and motility even it cause testis shrinkage and atrophy So I want to know we can use HCG (Gonadotropin) injection separately or not? If I want to take it how long I can tell my time period and I dnt want to take testrone therapy because it have drawbacks and future.
