The Claim

Dietary fat intake is associated with specific changes in testosterone and progesterone levels in healthy women, with no significant association observed for estradiol, luteinizing hormone, or follicle-stimulating hormone.

Source: Dietary fat intake and reproductive hormone concentrations and ovulation in regularly menstruating women.

In plain English

In healthy women, the amount of dietary fat consumed is linked to changes in testosterone and progesterone levels, but not to changes in estradiol, luteinizing hormone, or follicle-stimulating hormone.

See the scientific wording

The association between dietary fat and reproductive hormones is specific to testosterone and progesterone, with no significant effects observed on other key reproductive hormones such as estradiol, LH, or FSH in healthy women.

Why this might work

When more dietary fat is consumed, the body uses the extra cholesterol and fatty acids to make more testosterone and progesterone in the ovaries, but does not change how much estradiol, LH, or FSH are made.

What the research says

1 study
  1. Study: Dietary fat intake and reproductive hormone concentrations and ovulation in regularly menstruating women.

    This study found that eating more healthy fats slightly raises two hormones involved in fertility — testosterone and progesterone — but doesn’t change other important hormones like estrogen or the ones that trigger ovulation in women with regular periods.
