My boyfriend is 30 years old and still growing. my boyfriend is 30 years old and still growing. he doesn't know much about his condition as doctors haven't given him a lot of information. all we were told is that his testosterone levels are off and needs

Usually : Usually the growth plates(epiphyses) at the end of the bones fuse by a certain age and no further vertical growth is possible after that. If his "testosterone levels are off" as you mention, a condition called 'hypogonadism' that could delay the closure of the growth plates(epiphyses). X-rays of the long bones may give clues if this is occurring. A number of sophisticated blood tests for pituitary, thyroid, adrenal and gonadal function is needed to pinpoint the problem. If the growth is continuing after testosterone levels are normalized further evaluation needs to be done. This is an area of medicine dealt with by an "endocrinologist' . You may ask your primary care physician for a referral if he is not under the care of one already.

Hmmm : Hmmm . . . Seems to be defeating the purpose of having a physician if s/he can't tell you what's going on. Your boyfriend may have acromegaly (gigantism) which means too much growth hormone. This may be due to a tumor in his pituitary which may be crowding out the cells responsible for signaling his testes to produce testosterone & sperm. Sometimes, an operation can remove the tumor. Other times, the tumor is too small to see. All this is conjecture. Have him ask his doctors for more information (until he's satisfied) and for sources of where to look for more information and support groups. Good luck!
