what causes micropenis
Causes of MicroPenis. Micropenis is generally believed to be caused by the penis of a male babyâs penis failing to increase in length after the first trimester of pregnancy. Most indications point to a hormonal issue to be responsible for the condition.
Micropenis may also be caused by isolated growth hormone deficiency. It can occur as a primary idiopathic structural anomaly or may be associated with a genetic syndrome. The most common cause of micropenis is abnormal hypothalamic or pituitary function that leads to hypogonadotropic hypogonadism.
