Small penis causes

The main causes of small penis are insufficient gonadotropin secretion, excessive gonadotropin secretion, genetic factors, etc.

1. Insufficient gonadotropin secretion Small

penis may be due to hypothalamic pituitary dysfunction, resulting in insufficient gonadotropin secretion, low testosterone levels secreted by testes, affecting the normal development of the penis.

2. Excessive gonadotropin secretion

Small penis is mainly related to the testis itself. The testicular response to gonadotropin is abnormal, and the testosterone secretion is weakened. Through the negative feedback mechanism, excessive gonadotropin secretion is caused, resulting in hypogonadism.

3. Genetic factors

The size and shape of the penis may also be related to family inheritance.
