自从1903年AlberS—Schonberg首先报道了电离辐射对性腺的损伤作用以来,有关辐射对睾丸功能影响的资料很多。但资料多为急性大剂量辐射所致睾丸内分泌功能的改变,而对慢性小剂量尤其是职业性受照者的报导却较少。为此,我们测定了医用X射线工作者的血浆睾 Since AlberS-Schonberg first reported the damaging effect of ionizing radiation on gonads in 1903, there is a lot of information on the effects of radiation on testicular function. However, most of the data are mostly due to the changes of testicular endocrine function induced by acute high dose radiation, while there are few reports on chronic low dose, especially occupational exposure. To this end, we measured plasma testis in medical X-ray workers
