    Because the amount of radiation used in a chest X-ray is much greater than that in a X-ray, the harm to the body is naturally greater. So what impact will a chest X-ray actually have on male sperm? Men who are preparing for pregnancy or have already had breast cancer should pay attention. Let's take a look at these aspects.

    Because the spermatogonia in the testicular spermatogenic epithelial cells are highly sensitive to radiation, the number of sperm will decrease after extensive exposure to X-rays, and the increase in abnormal sperm will even cause testicular atrophy in more severe cases. Therefore, chest X-rays have an impact on pregnancy. The X-ray used in chest X-rays is a relatively dangerous radiation source. When a man is exposed to 500 to 600 Ci of direct radiation, it may cause permanent infertility. It should be noted that if the body cells slowly repair after a large radiation source, it will also be accompanied by genetic damage. From this point of view, male sperm is still relatively sensitive, and male compatriots must pay attention to this problem.

    The impact of chest X-rays on male sperm mainly refers to the impact of X-rays on male sperm. Radiation will harm male testicular spermatogenic cells, affect sperm production, and even cause an increase in abnormal sperm. Therefore, it is recommended that if one of the couples is exposed to X-ray radiation during the pregnancy preparation period, it is safer to postpone the pregnancy preparation period from 3 months to more than half a year.

    Men's testicles are very sensitive to rays. After being exposed to X-rays for a long time, the sperm count will decrease and the sperm abnormality will increase; in severe cases, the testicles will atrophy. Therefore, x-rays must have an impact on pregnancy. When the human testicles absorb a dose of 100 rad, it can cause sperm deficiency. It takes more than 1 year for a male's sperm production to reach pre-ejaculation levels or to have reproductive function. If a man is exposed to direct radiation of 500-600 curies, permanent infertility will occur; if he is exposed to direct radiation of 250 curies, temporary infertility will occur within 1 year.

    A general chest X-ray is an item that doctors often do to check for pulmonary symptoms or for physical examination. Nowadays, radioactive machines in hospitals have many protection measures, and the harm to people is generally not great. However, couples who plan to have children should stop taking non-traditional fluoroscopy, chest X-rays and other tests one year in advance, at least half a year. If it has already happened, the pregnancy plan should be postponed appropriately.
