Q: I have an 8 years old son. I've noticed that the size of his genitals (testicles and penis) is unusually small. These organs do not seem to be growing with age, as is the case with the other children of his age. Is this a serious problem or will it improve with age? We do not notice any erection also.

A:The growth of the genitals in boys is not very much between the ages of 4 to 11 years. The next phase of growth will be at puberty. You should not be very anxious. However, consult a paediatric surgeon who will establish whether the size falls within the acceptable normal range. Erections in boys usually happen early morning or just before they have to go to pass urine.
