What are the factors that affect penis size after erection?

1. Penile enlargement and genetic factors Like other organs of the body, the size and morphological characteristics of the penis are controlled and influenced by genetic factors.

2. The expansion, development and nutritional status of penis Generally speaking, adult males are physically strong and tall, and the external genitalia, including penis and scrotum, are well developed. The penis may be thicker, and vice versa, but it is worth pointing out that the size of the penis is not directly proportional to the height. It is often seen that some men whose height is less than 1.60m can reach 18cm or more during erection.

3. Penile enlargement is related to obesity. Some men with prominent fat in the lower abdomen, pubic symphysis and perineum tend to have poor penis development, which is relatively short compared with normal men. Indeed, compared with the huge body, this short penis may bring some difficulties and disappointment to the sexual life after marriage.

4. Penile enlargement is also related to other aspects, such as endocrine disorder, insufficient androgen level, penis retraction caused by testicular or scrotal swelling, etc. All these may lead to short penis.
