Progesterone and Fertility: Understanding its Fundamental Role

Puntos Importantes:

Progesterone, the hormone driving your dream of becoming a mother or father, is key to female fertility. When it’s lacking, it can become a silent obstacle. At Ingenes we understand how much reaching motherhood or fatherhood means to you, which is why we care for every detail of your hormonal balance.

What does progesterone do?

Known as “the pregnancy hormone,” progesterone prepares the uterus to receive the embryo and sustains it during the first weeks. Adequate levels create a welcoming environment for implantation and early development. If you think your body needs help, in this article we explain how to detect and correct a possible deficiency.

Warning signs

Low progesterone shows up as irregular cycles, spotting before your period, or difficulties conceiving. At Ingenes we use precise blood tests (measuring ng/mL) to detect imbalances and give you a clear picture of your reproductive health.

Impact on your dertility

Without enough progesterone, implantation can fail or the risk of early miscarriage increases. Our team evaluates your hormonal profile and, if necessary, includes studies on the embryo factor to maximize your chances of success.

Frequently Asked Questions

Can low progesterone cause implantation failures?

Yes. This hormone prepares the endometrium to nourish the embryo. If levels are low during the luteal phase, the endometrium may be too thin. Measuring progesterone 7 days after ovulation helps determine if supplementation is needed. Sometimes combining progesterone with luteal support in IVF improves implantation rates. Always follow your specialist’s prescribed doses.

When should progesterone be measured after ovulation?

About 7 days after ovulation (day 21 in a 28-day cycle). It should exceed 10 ng/mL. Blood testing is the most reliable method. If your levels are low, your doctor may recommend 100–400 mg/day of vaginal or oral progesterone. Do not self-medicate; always seek specialist guidance.

Natural ways to boost progesterone?

An balanced lifestyle helps: a diet rich in vitamin B6 and magnesium, stress control with yoga or mindfulness, and maintaining a BMI between 18.5–24.9. Avoid excessive exercise. But if the imbalance is significant, medical therapy is the safest way to reach optimal levels.

Can supplements prevent miscarriage?

In women with a weak luteal phase or recurrent losses, vaginal progesterone (200–600 mg/day) may improve the chance of maintaining pregnancy until week 10–12. Speak with your specialist to determine the route, dosage, and duration based on your history.
