患隐睾症的儿童到成年以后,如果睾丸仍在腹腔中不下降到阴囊内,睾九就不能生成精子。但患者仍能保持正常的第二性征性行为及发育。如用手术将睾丸复位到阴囊内,睾丸即逐渐恢复正常的造精功能。这已是数十年前众所公认的事实。关于睾丸为何在腹腔内不能生成精子,在阴囊内就能生成精子。此点,也早为生理学者阐明。阴囊遇冷皱缩保温,遇热松弛散温,具有良好的调温作用。正常情况下,阴囊内的温度低于体温2—2.5℃。由此可见,睾丸的正常造精
Children suffering from cryptorchidism to adulthood, if the testicles still in the abdominal cavity does not fall into the scrotum, testis nine can not generate sperm. However, patients can still maintain the normal second sexual characteristics and development. Such as surgery to testis reset to the scrotum, testis that is gradually restored to normal sperm function. This is a well-established fact decades ago. About why the testes can not produce sperm in the abdominal cavity, can produce sperm in the scrotum. This point, as early as physiological elucidation. Scrotal shrinkage cold insulation, case of loose loose temperature, with good thermostat effect. Under normal circumstances, the temperature inside the scrotum 2-2.5 ℃ below body temperature. Thus, the testes normal sperm
