It has been 12 years since I married my beloved wife and 10 years since I tried to get pregnant. When I was about to give up, I was fortunate to have the child I had expected for a long time, and I was thinking that from now on I would try my best for my family, I was surprised. Does that mean my sperm is infertile? Who is the child in my wife's belly? All types of suspicion are forming and it makes me crazy. I could not solve my work, so today I decided to ask my wife.
