I believe many people have heard this joke: girl looked at the newspaper, her boyfriend, said: “hey, you see, the sperm and a subsidy of 200 yuan.” M: “What do you want?” Woman: “If you can stand , I want to buy a house during the year … “Well, sperm really reward you? What kind of person in order to sperm? Today we’ll learn more about sperm donation it.
Q1. sperm reward? How much is it?
A: want the sperm to get rich or a little too optimistic, however, the sperm donor can really get a substantial amount of funds. Beijing sperm bank, for example, the complete set of sperm process a total of about 3000 yuan reward, this is indeed a tempting conditions, but not all people can donate.

A: As long as you are age 22-45 years of age, the Chinese nationality, health, non-hereditary diseases and family history, nearly two years in the local relatively stable residence and work non-sperm bank staff and their families. After passing by the semen screening and physical examination, you can become a sperm donor.
Q3. to donated sperm need to meet certain standards? If the failure is not normal?
A: sperm before the first 2-3 times a screening of semen quality (sperm density, motility, curve speed, linear speed, average path velocity of sperm cephalic swing amplitude, linear, forward , whipping frequency, etc.) and cryopreservation experiments, by those who continue to physical examination and blood tests to check, all in order to become official sperm donor. For fine screening in accordance with the technical specifications of the Ministry of Health is very strict, especially semen quality with the requirements of the standards are higher than the general male detection, think not difficult to understand, and can come up with sperm after freeze up get to be higher than the requirements to take advantage of fresh points.
from March 2003 to December 2010 as Shanghai sperm bank sperm donor volunteers, only 16.2% selected. Because they require higher than normal, so people that are not selected do not worry about the sperm bank refused to does not mean that the body and fertility is not normal.
Q4. donated sperm to do for handling?
A: First, the semen will be the first at room temperature for 30 minutes until liquefied after the protective agent mixed and refrigerated. Because sperm are actually very fragile, very easy to damage in the process of freezing and recovery, so they need to add a protective agent, used cryoprotectants glycerol, TEST-yolk, dimethylacetamide (DMA) and egg yolk (sperm food good ah ……), then you can enter the library refrigerated. With the development of science and technology, carbon dioxide dry ice freezing method has gradually been eliminated, replaced by a liquid nitrogen cryopreservation, including slow and fast freezing, in addition to 4 ° C freezing.
Q5. donated sperm to what purpose?
A: save the semen used in supply caused by male factor infertile couples the implementation of assisted reproductive technologies, and for inbreeding or male couples have a family history of genetic disease to provide a choose eugenics. In China, a sperm donor, sperm up to the supply of five women to conceive, to a large extent to prevent future generations of inbreeding. In addition research institutions may apply for, obtain donated sperm as research material.
Q6. sperm do not volunteer to donate it? Why use have to spend?
. A: sperm bank as a place to donate sperm and the preservation of sperm, are non-profit public welfare institutions for the purpose of all sperm trading is prohibited. So why the supply is not sterile sperm need to be charged? This is because the sperm bank’s operating costs are very high, including semen analysis and freezing the required supplies, liquid nitrogen consumption, depreciation of equipment and personnel costs, Donors, lost wages, transportation costs, laboratory examination fees, Therefore, the need to charge a fee.
Q7. successful people sperm to give birth to smarter offspring?
A: and some infertile couples may apply for the use of sperm relative source of good sperm, or even hope I can get the celebrity sperm, it is not a celebrity’s sperm contribute to the eugenics it? This is a fair question.
many men, successful careers, have made their places celebrity may have entered the fourth decade. Scientific research shows that men over the age of 40, significantly reduced testis weight, testosterone levels begin to decline after the age of 50, testosterone levels in a sharp decline in sperm reduce the normal rate. Therefore, the celebrity sperm may not be high-quality sperm. Moreover, the relevance of heredity is an objective reality, genetic, with intelligence, and other factors are also open to question. Moreover, even if the child has a mind and talent of the “celebrity”, it must be successful? I am afraid that is also wishful thinking.
fact, in our daily lives, injury Zhong Yong “abound. So, if the parents want their children to succeed, rather than in the hands of a celebrity sperm, I think that should enhance their children’s education, children have lofty ideals and goals, and the unremitting efforts of.
Q8. born children rely on the sperm in the sperm bank, to know his father exactly who is it?
A: according to China’s relevant policies and regulations, Donors who are confidential for the refinement as well as their offspring. But does it also deprived of their refinement and their descendants the right to know? Have to say that this is very contradictory. However, the British opened the first of its kind, in this regard since April 2005, the descendants of British refinement after the age of 18 has learned that the rights of the father of their own physiology, however, this approach is appropriate remains to be the time to test.
