Ds anxious about lack of development (puberty).

[Solo]

My Ds will be 15 in August. He's 6'3" and very slim and came to me in tears last night.

He told me he's worried about his lack of underarm hair (school kids take the mickey) and muscle mass ~ or lack of it and that his voice will not break. He has a mass of pubic hair (though he seems to think it's not) and as far as I can tell, everything in his boxers is developing normally.
He says he's spent days on the internet looking at possible reasons for it and has come up with something that says a lack of sleep can cause a delay, and he does have sleep issues that I've had him to the doctor about, but was no help if I'm honest.
I've tried to reassure him that everyone develops at a different rate, but of course, he doesn't want to be lagging behind.
Can anyone give any thoughts or advice that I can help him with or is anyone else going through this with their child or gone through it and come out the other side with minimal 'damage' as I'm at a loss really.

Ds doesn't know his father, so can't talk to a man about it and also doesn't know his paternal history etc, so doesn't know if it's a family trait being late.
My brother's voice never 'broke' it just deepened, but his Ds's voice did seem to break.

Argh! what a minefield!!

Elderflower I don't I'm afraid. Ds is taller than his father as an adult though.

I can only hope that development happens and that Ds is happy at the end of it :) time will tell I suppose!! :)

I've only just found this thread - please get your son checked out by GP and ask for a blood test. I had similar problems with DS1 who refused to see GP, backed up by DH for a while. Eventually it was clear he looked a lot younger than most of his friends and he agreed to see GP, who did not seem very concerned but said he would do a blood test "just in case" . It turned out DS1 had a prolactinoma - his testosterone levels were very low, prolactin sky high and if it had been allowed to grow his sight would have been at risk as it presses on the optic nerve. All sorted out with medication in the end but could have had very serious consequences.

Higgle I'm glad you got Ds sorted out; huge relief for you all.
My Ds does not look particularly young for his age, though I do think of him as 'baby faced.'

If I had to think of something to worry about with a name attached, I think it would be Marfan Syndrome tbh, but thanks for the heads up re prolactinoma.
