How reproduce a boy baby?

To conceive a boy, the sex of the baby is primarily determined by the sperm from the male partner, which can carry either an X (female) or Y (male) chromosome. Some theories suggest timing intercourse closer to ovulation may increase the chances of conceiving a boy, as Y-sperm are thought to swim faster but have a shorter lifespan than X-sperm. However, these methods are not scientifically guaranteed, and the sex of the baby is ultimately a random genetic outcome. For guaranteed sex selection, medical procedures like preimplantation genetic diagnosis (PGD) may be considered.
