Considering most teenagers start puberty at around 13 or 14, no, you're not 'weird', nor should you be worried. There is no reason whatsoever that you should contact a medical professional. Puberty will kick in sooner or later, and some teenagers start at around 16 or 17. Just remember - Don't worry!
The definition of delayed puberty in a boy is a boy who has completed his 14th year with no signs of pubertal development. If you are older than 14 and have not yet had any outward signs of going through puberty, you should contact your doctor to determine the underlying cause.
It is possible the child is having early Puberty so you should take him to your Doctor as a precaution just in case.
If a boy has no testicles, then his body will not go through puberty on its own, but his doctor will have him on a hormone regimen that will cause him to develop just like all the other boys his age, and nobody but the boy and his family will even know the difference.
Sperm is produced in the testicles once the boy has started puberty.
If you have not reached puberty at 18 you need help from a doctor to start it with medical help.
It would be early for a boy which is classed as precocious puberty. See your Doctor for advice.
This is something you should take up with your family doctor.
It's not necessary to know when he started puberty. Most boys start at around 12 or 13-years-old.
The size of a boy's nipples grow somewhat during puberty, so it will be dependent on his age and his stage in puberty.
17 sounds a bit late to have not even started. I'd contact a doctor and see if there's any hormone problems.
If you are 100% sure it is body odor and not just sweat, then your son could possibly have started puberty, but because he is at a young age ask him if he has underarm or pubic hair, if yes, then he has defiantly started puberty. and he could possibly finish puberty at 13 or 14
Do you mean that the boy (you or your son?) has only one teste inside his scrotum and the other teste is undescended (and still located within his abdomen?) If this is the case go and see your doctor, as soon as is practicable. A boy's testes should both have descended either before birth or soon after, definitely long before the onset of puberty. During puberty a boy's testes increase a great deal in size and this growth, inside the abdomen is the likely cause of the pain. It may be possible for a doctor or specialist to descend the testes or it may have to be removed. Either way it should not remain within the abdomen.
