It's been 12 years since I married my beloved wife, and 10 years since I've been trying to get pregnant. When I was about to give up, I was blessed with my long-awaited child, and I was thinking that I would do my best for my family from now on. I was astonished. Does that mean my sperm is infertile? Whose child is the child in my wife's belly? All sorts of suspicions were building up and it was driving me crazy. I couldn't handle my work, so I decided to question her wife today.
