Donations can be in money, goods, blood, organs and bone marrow. But what happens when you mix heartfelt charity with a handful of self-gratification? Sperm donation.
And college students are taking a leading role in this field in China, said chinanews on its website.
Nearly 10 percent of China's couples cannot conceive, with male infertility being the reason for one-third of them. Experts put the blame on pollution, work-related stress and unhealthy lifestyle.
College students, however, have come to the rescue of many such couples, even though sperm donations still fall short of the demand, said an official of Beijing's only sperm bank. The country has 10 such banks.
Myths such as "one drop of semen equals 10 drops of blood" prevent people from donating sperm, said Chen Zhenwen, director of the bank, affiliated to the National Population and Family Planning Commission of China.
Thankfully, college students don't share any such belief and "are more willing to help", Chen said. "Many of them are Beijing Olympic volunteers."
Several hundred volunteers, half of them college students, have approached the sperm bank since it opened in late 2005.
A donor's sperm can be used to impregnate five women, according to the ministry of health here.
"We donate blood and bone marrow, then why can't we donate sperm. After all, it can help fulfil barren couples' dream of having a child," said a donor Xiao Wang (name changed). But the Beijing college student hasn't told his girlfriend about the donation.
