I'm a 64 year old male diagnosed with hypogonadotropic hypogonadism about 15 years ago ( no LH or FSH resulting in little testosterone) I have since been using topical testosterone which in many ways improved my life. However in the last year or so I have noticed breast enlargement . My endocronologist checked and agreed it was gynecomastia., If I had reduction surgery what are the chances that continued testosterone use would cause this to return?
