The Claim
In regularly menstruating women, higher dietary intake of total fat and polyunsaturated fatty acids is associated with a 4.0% to 4.1% increase in free and total testosterone concentrations.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Women who consume more total fat and polyunsaturated fatty acids have slightly higher levels of free and total testosterone in their blood compared to those who consume less.
See the scientific wording
In regularly menstruating women, higher dietary intake of total fat and polyunsaturated fatty acids (PUFAs) is associated with a 4.0% to 4.1% increase in free and total testosterone concentrations, suggesting a link between fat consumption and androgen levels in healthy women.
When a woman eats more fat and polyunsaturated fatty acids, her body uses the extra cholesterol and fatty acids to make more testosterone in the ovaries. This happens because the cells in the ovaries get more building blocks and activate enzymes that turn those building blocks into testosterone, leading to higher levels in the blood.
What the research says
1 studyThis study found that women who ate more fat, especially certain healthy fats called PUFAs, had slightly higher levels of testosterone in their blood—just a tiny bit more, but it was a real and measurable difference.
