Donating sperm is one of the most generous things a man can do, as it gives others the chance to have a baby. 

The number of sperm donors has seen a sudden rise after a local newspaper reported that Chongqing sperm bank has been put into operation.

After three years of preparation and construction and one year of trial operation, the sperm bank finally got approval from Chongqing Municipal Health and Family Planning Commission.

Potential candidates need to make an appointment for health examination before donation, said a doctor at the sperm bank. Every day, the sperm bank arranges 15 people to donate their sperm.

According to the introduction of the bank, only married or single men who meet requirements such as being 22 to 45 years of age, a height of at least 1.65 meters, being in good health, with well-formed features and having education at junior college level or above can donate sperm.

They must also be confirmed as not having hereditary or sexually-transmitted diseases through laboratory examination. Six months after the sperm donation, a volunteer will be required to have a blood test again.

Only after one is confirmed that he hasn’t been infected with HIV can his sperm be qualified for supply to the outside.

Usually, only 24 percent of male applicants who meet the initial criteria qualify and not all qualified applicants become donors at last, said the doctor.

A sperm donor can earn as much as 5,000 yuan (US$ 771.9) once. Every walk-in applicant will have 50 yuan of transportation allowance.
