'Donation changed my life'

Kang Jun, 34, (not real name) is a civil servant in Taiyuan, Shanxi province.

I decided to donate because my brother became infertile after getting injured in a car accident which led divorce. If they knew about the sperm bank, they wouldn't have divorced probably.

The donor couldn't have a sex life during the donation period which would last about half a year and forbid taking a sauna, drinking alcohol or smoking. I kept the donation secret from my wife but she became suspicious.

I have been looking for different excuses to comfort her.
