The problem of declining sperm quality among modern men is very common. Some people's own sperm is substandard and cannot reproduce normally, so they can only conceive the next generation by taking sperm from others. Therefore, some men are willing to donate sperm for free to help others. However, can sperm donation be donated whenever you want? What are the requirements for sperm donation? Must be a college student Donating sperm is not as simple as people generally believe. There are strict requirements: you must be a college student, be over 165 cm tall, and your sperm motility must be four times that of a normal person. These are just the basic requirements for donating sperm (based on these requirements, only one in ten donors can meet them). Semen test passed To donate sperm, the sperm bank will conduct free physical examinations and semen tests on all applicants, and only qualified applicants can donate. To donate sperm, you cannot have systemic diseases and serious organic diseases, such as heart disease, diabetes, tuberculosis, liver disease, urogenital system diseases, blood system diseases, hypertension, mental illness and leprosy, etc.; you should also not have long-term exposure to radiation and toxic and harmful substances; myopia should not be greater than 500 degrees, and you should not be color blind or color weak. In addition to the high physical requirements, the sperm donor's semen requirements are also very high. Therefore, not many people meet the conditions, and only 1/3 of the people who come to donate sperm are qualified. Although college students are at the peak of their reproductive years, the pass rate of their semen is basically at this ratio, that is, only 1/3 of them are qualified. Tang Lixin said that if the semen is unqualified and does not meet the sperm donor's standards, it does not mean that their body and fertility are abnormal. This is like selecting astronauts. Not being selected does not mean that their body is not good. It is mainly because the sperm bank has very high requirements for the sperm donor's semen. For example, the sperm concentration must reach 60 million/ml, and the sperm with vitality (straight line movement) must account for 60%; the sperm must have a normal shape, that is, the sperm must have a head and a tail, and the sperm must be "handsome". Tang Lixin said that the last standard is 26% higher than that in foreign countries, where the proportion of normal sperm shape is only 4%. It can be seen that men whose semen meets the "storage" standard are rare. |
