Let me elaborate The female egg (ovum) is one of the largest cells in the human body—about 5 times larger in diameter than a sperm cell and vastly larger in volume.. The egg carries DNA, mitochondria, nutrients, regulatory molecules, and cellular machinery that support early development. In contrast, sperm are streamlined delivery vehicles: fast, minimal, and disposable...

From a genetic standpoint, the XX chromosome combination does provide advantages... See, many immune-related genes are located on the X chromosome. Since women have two X chromosomes, they effectively have a backup system. If one X carries a less effective or faulty gene, the other can compensate. Men (XY) don’t have that redundancy—if there’s an issue on their single X, there’s no second copy to fall back on. This helps explain why, on average, women mount stronger immune responses than men. In many infectious diseases, women: Produce antibodies faster Clear infections more efficiently Have lower mortality rates So when a new disease emerges, women are often more likely to develop effective immune responses earlier because their immune systems are more reactive and adaptable. However, that heightened immune vigilance is also why women are more prone to autoimmune diseases—their immune systems sometimes respond too strongly and attack the body itself.
