Cryptorchidism at age 8 may affect fertility.
Unilateral or bilateral cryptorchidism may affect fertility. The appropriate temperature for the testes is 1-2°C lower than the body temperature. If the testes are retained in the posterior peritoneum, inguinal canal or the entrance to the scrotum for a long time, the higher temperature will affect the spermatogenic function of the testes and may lead to infertility.
In patients with cryptorchidism, the ideal age for effective fertility preservation is 12 to 24 months after birth. The decisive treatment for cryptorchidism should be completed in the first 6 to 12 months of life, and at least by 18 months, as the timing of the treatment may affect spermatogenesis, hormone secretion, and tumorigenesis in adulthood.
Postnatal spontaneous descent of the testes can occur within the first 6 months of life, after which the likelihood decreases and spontaneous descent is no longer possible at 1 year of age. Once cryptorchidism is recognized, professional treatment should be sought as soon as possible, so as not to miss the best treatment period.
