Hormonal

Abdominal obesity in women causes reproductive disorders, including anovulation and infertility, primarily through functional hyperandrogenism and hyperinsulinemia which overstimulate ovarian steroidogenesis and decrease sex hormone-binding globulin.

If you have abdominal obesity and are struggling with irregular periods or infertility, your body's high insulin levels may be driving excess androgen production, which stops ovulation. The most effective first step is often modest weight loss (even 5-10%) combined with lifestyle changes to improve insulin sensitivity, which can restore ovulation and fertility without needing immediate pharmacological intervention.

GoodSupportsHIGH confidence
In women with the polycystic ovary syndrome, abdominal obesity may be co-responsible for the development of hyperandrogenism and associated chronic anovulation, through mechanisms primarily involving the insulin-mediated overstimulation of ovarian steroidogenesis and decreased sex hormone-binding globulin blood concentrations.
