A growing number of college students in China have become sperm donors due to the improved attitudes and increased subsidies.
Sources with the Guangdong human sperm bank said that more than 95 percent of sperm donors are college students, whose donations are helping to ease the sperm shortage that has been troubling infertile couples for several years.
Only healthy men between the ages of 22 and 45 can give sperm once in their lifetime, according to the Ministry of Health. Gay men and foreign nationals are prohibited.
Men must visit a sperm bank three times for initial tests and undergo blood screening if their sample makes the grade. They then have to return about 10 times to donate.
A qualified donor can receive as much as 450 dollars in subsidies if he finishes the sperm process, sources with the bank said.
"Some students donate sperm for the increased subsidies, but most regard the donation as an act of charity to help those needing artificial insemination," said Tang.
In China, about 10 percent of couples, many of whom live in big cities, are infertile, according to the bank.
"The situation has improved in recent years as more people, especially college students, have developed an interest in donating sperm," said Tang.
"Students are much more open-minded than older generations. Many students with master and doctor degrees come to donate sperm. Their sperm is more valuable," he added.
