Boys do not conceive children.
Pregnancy begins with the union of sperm and egg, and then the fertilized egg is similar to a plant seed planted in fertile soil in order to thrive and eventually develop into a full-fledged living organism. When the fertilized egg enters the female uterine cavity, the uterine lining provides a nutrient-rich environment that creates the conditions for implantation of the fertilized egg and, through the placenta, provides a steady stream of nutrients for the growth of the fetus.
Men cannot ovulate without ovaries, and they do not have a uterus to conceive a child, so boys will not be able to carry a child.
The prerequisites for a successful pregnancy include good health for both spouses and good sperm quality for the male. Therefore, both spouses should go to the hospital for a routine checkup and learn about pregnancy preparation before they are ready to get pregnant.
