The Claim

Carriers of rare myostatin gene variants exhibit no significant association with alterations in follicle-stimulating hormone levels, age of menarche, age of menopause, number of live births, or risk of polycystic ovary syndrome.

Source: Humans with function-disrupting variants in the myostatin gene (MSTN) have increased skeletal muscle mass and strength, and less adiposity

Support is ahead, but a single strong opposing study can change this.

In plain English

People with rare variations in the myostatin gene have the same levels of follicle-stimulating hormone, same age of first period and menopause, same number of children, and same risk of polycystic ovary syndrome as people without these variations.

See the scientific wording

Carriers of rare myostatin gene variants show no significant association with altered levels of follicle-stimulating hormone, age of menarche or menopause, number of live births, or risk of polycystic ovary syndrome, suggesting that myostatin disruption does not impair reproductive health in humans.

Why this might work

When the myostatin protein is disrupted, muscles grow larger and body fat decreases, but this change does not affect the hormones that control puberty, menstrual cycles, fertility, or ovarian function. The body's reproductive system continues to operate normally despite these muscle and fat changes.

  1. Study: Humans with function-disrupting variants in the myostatin gene (MSTN) have increased skeletal muscle mass and strength, and less adiposity

    People born with a rare muscle-building gene mutation don't have problems with puberty, fertility, or hormone levels — their bodies just have more muscle and less fat, with no signs of reproductive issues.
