What do newcomers need to know about sperm donation?

I believe many people have heard this joke: The girl looked at the newspaper and said to her boyfriend: "Look, you can get a subsidy of 200 yuan for sperm donation." Man: "What do you want?" Woman: " If you can bear it, I want to buy a house within this year?" So, are there really any rewards for donating sperm? Who can donate sperm? Today let’s learn more about the details of sperm donation. \x0d\　\x0d\　Q1. Are there any rewards for sperm donation? How much does it cost? \x0d\　\x0d\　A: It is a bit fanciful to think about getting rich through sperm donation, but sperm donation can indeed get a considerable amount of money. Taking the Beijing Human Sperm Bank as an example, you can get a reward of about 3,000 yuan per day for completing a complete sperm donation process. This is indeed a very tempting condition, but not everyone can donate. \x0d\　\x0d\　Q2. Can I donate sperm? \x0d\　\x0d\　A: As long as you are 22-45 years old, Chinese nationality, in good health, have no hereditary diseases or family history, have a relatively stable residence and job in the local area in the past 2 years, and are not sperm bank staff and family members. After passing the semen screening and physical examination, you can become a sperm donor. \x0d\　\x0d\　Q3. What standards do sperm need to meet if you want to donate? Is it abnormal if it fails? \x0d\　\x0d\　A: Before donating sperm, you first need to conduct 2-3 semen quality screenings (including sperm density, motility rate, curve speed, linear speed, average path speed, sperm head side swing amplitude, linearity , forwardness, frequency of whipping, etc.) and cryoresuscitation experiments. Those who pass will continue to undergo physical examinations and blood tests. Only those who pass all can become official sperm donors. The screening of sperm donors is very strict in accordance with the technical specifications of the Ministry of Health. In particular, the requirements for semen quality are higher than the standards for general andrological testing. It is not difficult to understand that sperm can be used after being frozen. , no matter how you use it, you have to be more demanding than using it fresh. \x0d\　 \x0d\ For example, from March 2003 to December 2010, only 16.2% of sperm donation volunteers were selected for the Shanghai Human Sperm Bank. Because the requirements are higher than ordinary people, people who are not selected do not have to worry. Being rejected by the sperm bank does not mean that the body and fertility are abnormal. \x0d\　\x0d\　Q4. What should be done with donated sperm? \x0d\　\x0d\　A: First, the semen will be left at room temperature for 30 minutes. After liquefaction, it will be mixed with a protective agent and refrigerated. Because sperm are actually very fragile and easily damaged during freezing and recovery, they require the addition of protective agents. Commonly used cryoprotectants include glycerol, TEST-yolk, and dimethylacetamide (DMA). and egg yolks (are the sperms eating well?), etc., and then they can be put into storage and refrigerated. With the development of science and technology, the carbon dioxide dry ice freezing method has been gradually eliminated, replaced by the liquid nitrogen cryopreservation method, which is divided into slow and fast freezing methods, as well as the 4°C freezing method. \x0d\　\x0d\　Q5. What are the uses of donated sperm? \x0d\　\x0d\　A: Preserved semen is mainly used to provide couples with infertility caused by male factors to implement assisted reproductive technology, and can provide an alternative eugenics for couples who are married to close relatives or whose husband has a family history of genetic diseases. method. In China, one sperm donor's sperm can provide fertilization for up to five women, which also prevents incest marriages in offspring to a large extent. In addition, scientific research institutions can also apply to obtain donated sperm as scientific research materials. \x0d\　\x0d\　Q6. Isn’t the sperm donated by volunteers? Why spend money when using it? \x0d\　\x0d\　A: The Human Sperm Bank is a place for sperm donation and sperm storage. It is a non-profit public welfare institution. All sperm sales are prohibited. So why is there a charge for supplying sperm to infertile people? This is because the operating costs of a sperm bank are very high, including consumables for semen analysis and freezing, consumption of liquid nitrogen, depreciation of instruments and equipment, personnel management expenses, sperm donors’ lost time, transportation expenses, laboratory inspection expenses, etc. So a certain fee needs to be charged.

\x0d\　\x0d\　Q7. Can the sperm of successful people be used to produce smarter offspring? \x0d\　\x0d\　A: Some infertile couples may hope to get sperm from relatively good sources when applying for the use of sperm, or even hope to get sperm from celebrities. Does that mean that celebrity sperm will contribute to eugenics? This is a question worth considering. \x0d\　\x0d\　First of all, many men have successful careers and may have entered their forties when they make a name for themselves and become celebrities. Scientific research shows that after a man reaches the age of 40, the weight of his testicles begins to decrease significantly, and the testosterone level begins to decline. After the age of 50, the testosterone level drops sharply, the sperm decreases, and the normal rate decreases. Therefore, celebrity sperm may not be "high-quality sperm." Moreover, although heredity exists objectively, the degree to which heredity is related to factors such as intelligence is still open to question. Moreover, even if a child has the brains and talents of a "celebrity", will he definitely be successful? I'm afraid it's just wishful thinking. \x0d\　\x0d\　In fact, in our daily lives, there are many examples of "hurting Zhongyong". Therefore, if parents want their children to succeed, instead of relying on celebrity sperm, I think they should strengthen their children's education so that they can have lofty ideals and goals and work tirelessly for them. \x0d\　\x0d\　Q8. Can a child born with sperm from a sperm bank know who his father is? \x0d\　\x0d\　A: According to the relevant policies of our country, the identity of the sperm donor is kept confidential from the sperm seeker and his offspring. But does this also deprive the seeker and his offspring of their right to know? I have to say that this is a very contradictory thing. However, the UK has set a precedent in this regard. Starting from April 2005, the offspring of British sperm seekers will have the right to know their biological father after the age of 18. However, it remains to be seen whether this approach is appropriate. test.
