No, bones themselves do not have a gender. However, skeletal features can often indicate the biological sex of the individual. The degree to which this is possible varies depending on factors like age and the specific bone being examined.
Sex Determination from Bones
Several references highlight that while bones don't inherently possess gender, certain characteristics can be used to infer the biological sex of the individual. These characteristics are more reliably observed in adult skeletons.
- Pelvis: The pelvis is often the most reliable indicator of sex, with distinct features adapted for childbearing differentiating adult females from males. [The pelvis tells the story. Distinct features adapted for childbearing distinguish adult females from males. Other bones and the skull also have features that can indicate sex, though less reliably. In young children, these sex-related features are less obvious and more difficult to interpret.]
- Other Bones and Skull: While less reliable than the pelvis, other bones and the skull can also exhibit sex-related characteristics. [Distinct features adapted for childbearing distinguish adult females from males. Other bones and the skull also have features that can indicate sex, though less reliably. In young children, these sex-related features are less obvious and more difficult to interpret.]
- Size and Mass: Generally, males tend to have larger skeletal size and bone mass compared to females. [Males have larger skeletal size and bone mass than females ...

- Accuracy Limitations: Determining sex from bones alone can be challenging, especially with isolated bones or incomplete skeletons. The accuracy depends on various factors, including the age of the individual. [Is it true that you can't tell the difference between male and females ... The short answer is an emphatic no.

Bone Health and Gender
Bone health is also influenced by biological sex and hormonal factors. Differences in bone structure start in childhood, with males typically having larger and stronger bone and joint surfaces.

Gender-affirming treatments can also influence bone health in transgender individuals. [Impact of gender-affirming treatment on bone health in transgender ...
