It's 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 enough to have the child I had been waiting for for a long time, and I was thinking that from now on I would do my best for my family when I was very surprised. Does that mean my sperm is infertile? Whose child is the child in my wife's womb? All kinds of doubts are forming and it's driving me crazy. I couldn't handle my work so today I decided to raise the issue with my wife.
