Why is male heart larger than female heart?

The statement that the male heart is larger is generally true, but it's important to remember that there is variation among individuals.

The average male heart is about 10% to 15% larger than the average female heart. This difference is mainly due to the fact that men are typically larger than women. However, there are also some physiological factors that contribute to the difference in heart size.

The heart is a muscle that pumps blood throughout the body. The amount of blood that the heart needs to pump is determined by the body's size and activity level. Men are typically more active than women, and they have larger bodies, so their hearts need to be larger in order to pump enough blood to meet their needs.

In addition to the physiological factors, there are also some hormonal factors that contribute to the difference in heart size. Testosterone, the male sex hormone, helps to increase the size of the heart muscle. This is why men typically have larger hearts than women.
