i would mention it to his mum and just see what she says.
perhaps she has already noticed it and seen someone about it and they've said not to worry?

Hi,
Have any of your baby's have long quite dark hairs on thier scrotum??
Sorry to keep on about it but im so worried there's something wrong.

I know im probably worrying over nothing but a few of them are long and quite dark??

both mine have fine hair on their scrotums too!, and they are fair haired,and pretty hair free elsewhere

Thank you so much.

my 3 boys all have very fine hair on their scrotums. tis normal

She would of told me if she had seen them, they are long im worried sick, i had 4 boys and have never seen anything like this before.

i am sure his mum has seen it if it is that noticeable

babies can have downy hair all over. even on their genitalia. it can be more noticeable with darker haired babies

Im baby sitting my 5 month old Grandson tonight.
When i was changing him for bed i got a hell of a shock! he has got hair on his scrotum
what on earth could be causing it ? I havent told him Mam yet as i dont want to worry her.
Any idea's anyone PLEASE.
