Testis in fetal period is longer in the abdomen, was born in 1-2 months before falling in the scrotum. If during testicular descent, en route or stagnation in the decline in bilateral testis, scrotal testis is not found, or only 1 testicle, this is called cryptorchidism.
Testes cannot be two main reasons for the decline: a mechanical factors, testicular descent and you want to rely on the gravity of the spermatic cord, if the spermatic cord is too short, or adhesions, or not, the testes cannot decline.
Another reason is a lack of gonadotropin in maternal, or hormone but bad testis, testis can only stay in place, or the limited fall and cannot reach the scrotum.
We know that the testicular sperm mature needs suitable temperatures, and the temperature of the scrotum is the most appropriate. Cryptorchidism of children when the infant is not affected, but 2 years later began development of testis, sperm cannot be formed, to testicular atrophy after adolescence, especially bilateral cryptorchidism is a major cause of infertility. Atrophy of testis cancer-prone.
Suffered from cryptorchidism in children is the best method of treatment in surgical secures the testis in the scrotum. Surgery is generally completed before 2 years. When at the age of children 2 testes still does not fall that required surgery. To early to go to hospital for treatment of bilateral cryptorchidism, can human chorionic gonadotropin in the treatment, if the effect is not good, then surgery.
