The Chinese make everything but ...
 In the past month, Li and his colleagues have given lectures in universities in Shanghai, including Fudan and Tongji, about the sperm crisis in an attempt to raise awareness among students.
It is reported that more than 300 students have contacted the Human Sperm Bank about donation. The bank now has 20-30 student donors a month.
"Our lectures are successful and popular on campus," said Li. "Many students attended my lectures, both boys and girls."
The lectures not only attracted new donors but also contributed to sex education.
"We can donate blood and stem cells, why not sperm?" said a university student surnamed Zhang. "I would be happy if my donation helped one family."
Nowadays, college students have become a major source of sperm donation in Shanghai, accounting for 70 per cent of the city's donors. Married men account for the remainder. "They tend to be more open-minded about making donations than the older generation," Li said, adding that additional contributions from other parts of the community also need encouragement. "Sperm donation could be considered a lofty act because it benefits infertile couples," said a graduate student, surnamed Wang, from Shanghai Second Medical University.
He said that as medical students, he and his peers were more likely to understand the meaning of sperm donation and to participate in it. "As far as I know, many younger college students would like to donate, though others are restrained by our traditions and the ethical codes of our society."
Besides sperm, he has also donated blood, though he has not revealed any of this to his family who live in East China's Shandong Province. "But my girlfriend agreed to it," he said.
The first step in the procedure is for the donor's sperm to be collected and examined, with the name and status of the donor being checked. After the lab examination, the sperm is frozen and given a code number while it awaits an HIV check. Roughly six months later, when the testing process is completed, the identities of acceptable donors are enciphered. The sperm is then ready to be selected and used, with reference being made to blood types and facial and bodily features. "Some foreigners have called me and expressed a willingness to donate sperm to our bank, but the rules stipulate that only Chinese citizens are permitted to donate in China," Li said.
sperm storage service
A sperm storage service designed as a system of "reproduction insurance" is being planned by privately-funded Wenzhong Hospital in Shanghai.
According to Dr. Fa Yifang, the hospital's chief of staff, the service would mainly target men aged between 20 to 25, the age when physical fitness is typically at its peak.
"Relatively fewer people choose to have children at this stage in their lives, when they're busy with school careers. Even among this group however, external factors such as environmental pollution, chemicals and microwaves can cause a deterioration in sperm quality," said Fang.
The Shanghai Municipal Human Sperm Bank also offers a sperm storage service for individuals seeking reproduction insurance, in addition to its principal function of providing healthy sperm to infertile couples. It is reported that 10 people have already decided to store their sperm in this way.
Li considers this kind of service to be quite risky: "Sperm storage is not the same as saving money in a bank. It is possible to store sperm and later discover it is not able to fertilize an egg after years of refrigeration, especially if it was not of especially high quality to begin with."
Li explained that human sperm banks had to sign detailed contracts with their clients to avoid potential conflicts over disappointment in the future.
Although the Human Sperm Bank was approved last year and quickly began to offer a sperm storage service, most residents were initially lukewarm about the idea of reproduction insurance. Most attention was focused on those who had become infertile after medical procedures or accidents, with the service regarded as a good way to reduce infertility risks. The idea of ordinary young people storing their healthiest sperm for future fertilization was a novel one, and approval by local government was unprecedented.
There have been increasing indications that sperm quality within the general population is deteriorating. An authoritative global survey shows that sperm density has decreased by 50 per cent since 1940 and continues to decline by a percentage point each year. It has even been predicted that the decline in sperm quality could ultimately lead to a worldwide fertility crisis.
Li expressed doubts about the more alarmist forecasts, saying they were not supported by the most comprehensive statistics available, although the patterns of modern living had affected sperm quality to some extent. He argued that the most effective way of addressing the sperm shortage problem was through public education.
