The size of the human heart differs between males and females; the female heart is generally smaller than the male heart.
The references indicate that a female heart is approximately one-fourth smaller than a male heart. Quantitatively, the average mass of a female heart is around 245 grams, which is approximately 26% less than the average mass of a male heart, which is about 331 grams (Molina and DiMaio, 2012, 2015).
Here's a summary in a table:
| Gender | Average Heart Mass |
|---|---|
| Male | 331 grams |
| Female | 245 grams |
This difference in size is a general trend and individual variations exist.
