Congenital hypoplasia of reproductive organs or partial disconnection after trauma leads to obvious shortness of reproductive organs, and the physiological response (erection) can not reach the length of normal people. People with short reproductive organs have stunted secondary sexual characteristics, erectile dysfunction, and even dysuria in severe cases.

Varicocele: Vasodilation, distortion or prolongation of the blood vessels in the spermatic plexus caused by blood stasis in the spermatic vein. This disease is mostly caused by the blood reflux of internal spermatic vein. The main symptoms are scrotum drooping, swelling and pain after standing, walking for a long time or heavy physical labor, and the varicose veins in scrotum are earthworm-like masses. Patients with abnormal sperm increase will lead to infertility. Hypospadias can wait until adolescence to start surgery. Children with hypospadias can't stand urination, which seriously affects their mental health. They need plastic surgery, otherwise it will affect the normal development of urination and reproductive organs in the future, and it will also lead to infertility in adulthood.
