My DS1 is coming up 18. Last year he was diagnosed as having a prolactinoma and is now on steroid treatment to reduce the pituitary and give those bits that produce all the hormones - including organising testosterone - a chance to get going again. He had virtually no testosterone production when all this started, about 8 months ago and is due to go back to see his specialist for more tests next month. He thinks he is getting a bit more hairy and his voice may be a bit deeper, but he is still stuck as looking about 13/14 and has no facial hair. He is a bit down about it as he feels it makes it hard for him to make friends, and I'm concerned it seems to be taking ages for the treatment to work. Has anyone else had any experience of this condition - how long does it take to become "normal" in terms of development? He will be off to uni this autumn and is a bit trepidacious about it all.
