Here’s the bottom line: pregnancy requires a uterus. Males and most XY females cannot become pregnant because they don’t have a uterus. The uterus is where the fetus develops, and pregnancy isn’t possible without it. In most cases, having a Y chromosome means having no uterus, so pregnancy isn’t possible.
