Dear Welcome to HCM We understand your concerns I went through your details. Spermatocele cannot cause low testosterone levels. In fact, low testosterone levels could be a cause for spermatocele. Low testosterone levels may not cause male breast enlargement. It is the excess female hormones, that causes enlargement of male breast. physical exercises and chest tightning exercises like push ups and pull ups and weight training can tighten chest muscles and thereby help in reduction of breast size.
