My friend's 8yo ds has been having greasy hair and spots/blackheads for about 6 months now and she has just noticed he has started growing pubic hair. Understandably she is freaked by this and has read all kinds of things on internet sites about precocious puberty causing growth spurt followed by no further growth at all as well as testicular cancers etc. Another of my friends dd started puberty at age 3/4 and it was caused by an adrenal tumour (benign) - Does anyone have any experience of early puberty in boys?
