Living with the Condition

Unless the male has pain associated with his groin or functional problems, being born with this condition is not technically a medical problem.

Scientists currently believe that a micropenis is created during fetal development. Hormonal imbalances in the womb or genetic defects occur and cause the penis to grow less than normal. Since androgen causes the penis to develop and grow, most researchers believe that micropenises are caused by a deficiency of androgen. At the first stage of penis growth, androgen makes the penis take shape and the scrotum form. Later on in the baby’s development, androgen will cause the penis to grow longer. Since the penis is still there with this medical condition, the androgen deficiency seems to be occurring later on.
