The Hidden Hormone Connection: How Testosterone and SHBG Shape Women’s Fertility

Testosterone, SHBG, and Fertility: Finding the Right Balance

When most people think about women’s hormones, estrogen and progesterone get all the attention. But testosterone, though present in smaller amounts, is just as important, especially when it comes to fertility and egg quality.

Testosterone helps eggs develop in the ovaries and supports ovulation. If levels are too low, eggs may not mature properly, which can make it harder to conceive. On the other hand, too much testosterone can throw cycles off completely, often showing up in conditions like PCOS. The key is balance. Having just the right amount creates the best environment for healthy eggs. Think Goldilocks!

This balance is influenced by sex hormone-binding globulin, or SHBG. SHBG is a protein made in the liver that binds to hormones like testosterone and estrogen, controlling how much of them are active in the body. When SHBG is too low, more “free” testosterone is left circulating, which can interfere with ovulation and egg quality. Low SHBG is often linked with insulin resistance and excess weight, while healthy SHBG levels help keep hormones in check and fertility on track.

The encouraging part is that lifestyle has a big impact. Moving your body regularly, eating balanced meals that keep blood sugar steady, and maintaining a healthy weight all help boost SHBG naturally. Estrogen also raises SHBG, which is one reason levels shift during the menstrual cycle. Even everyday choices, like choosing whole foods over extreme diets, can support this delicate hormone balance.

When testosterone and SHBG work together in harmony, women are more likely to ovulate regularly and produce high-quality eggs. Supporting this balance isn’t just about fertility; it’s also about feeling well, inside and out!
