Get tested with Superpower

If you’ve been postponing blood testing for years or feel frustrated by doctor appointments and limited lab panels, you are not alone. Standard healthcare is often reactive, focusing on testing only after symptoms appear or leaving patients in the dark.

Superpower flips that approach. We give you full insight into your body with over 100 biomarkers, personalized action plans, long-term tracking, and answers to your questions, so you can stay ahead of any health issues.

With physician-reviewed results, CLIA-certified labs, and the option for at-home blood draws, Superpower is designed for people who want clarity, convenience, and real accountability - all in one place.

Key benefits of Progesterone testing

• Reveals whether your body is producing enough progesterone to support cycles and pregnancy.
• Confirms ovulation occurred by detecting the hormone surge after egg release.
• Explains irregular periods, spotting, or unexplained mood and sleep changes.
• Guides fertility treatment by showing if progesterone support is needed for conception.
• Protects early pregnancy by flagging low levels that may increase miscarriage risk.
• Tracks luteal phase health to identify short cycles that affect fertility.
• Clarifies perimenopausal symptoms like heavy bleeding or cycle unpredictability.
• Best interpreted with cycle day, symptoms, and tests like LH or estradiol.

What is Progesterone?

Progesterone is a steroid hormone produced primarily by the ovaries after ovulation, with smaller amounts made by the adrenal glands. In pregnancy, the placenta becomes the major source. It belongs to a family of hormones called progestogens, which play essential roles in reproduction and the menstrual cycle.

The hormone that prepares the body for pregnancy

Progesterone transforms the uterine lining into a nutrient-rich environment ready to support a fertilized egg. It also helps maintain early pregnancy by preventing the uterus from contracting and shedding its lining.

A key player in the menstrual cycle

After ovulation, progesterone levels rise sharply during the second half of the cycle (the luteal phase). If pregnancy doesn't occur, levels drop, triggering menstruation.

Beyond reproduction

Progesterone influences mood, sleep, and bone health. It also counterbalances some effects of estrogen, helping regulate the body's hormonal equilibrium. In men, small amounts support sperm production and nervous system function.

Why is Progesterone important?

Progesterone is a steroid hormone that prepares the body for pregnancy and regulates the menstrual cycle, but it also influences mood, sleep, bone health, and metabolic balance. In women of reproductive age, levels fluctuate dramatically across the cycle - rising after ovulation and falling before menstruation - while remaining consistently low in men and postmenopausal women. Optimal values depend entirely on cycle phase, pregnancy status, and sex.

When progesterone runs low

Insufficient progesterone in the luteal phase can signal poor ovulation or a struggling corpus luteum, leading to irregular periods, difficulty conceiving, or early pregnancy loss. Women may experience heavy bleeding, premenstrual mood swings, anxiety, and sleep disturbances as estrogen goes relatively unopposed. Low levels also reduce the calming effect on the nervous system and may compromise bone density over time.

When progesterone climbs high

Elevated progesterone outside of pregnancy or the luteal phase may point to ovarian cysts, adrenal tumors, or certain cancers. High levels can cause fatigue, bloating, breast tenderness, and sedation. In pregnancy, progesterone naturally soars to sustain the uterine lining, but abnormal spikes warrant investigation.

The bigger hormonal picture

Progesterone works in concert with estrogen, thyroid hormones, and cortisol to shape reproductive health, metabolic function, and emotional resilience. Chronic imbalances increase risks for infertility, osteoporosis, mood disorders, and hormone-sensitive cancers, making progesterone a vital window into endocrine and whole-body wellness.

What do my Progesterone results mean?

Low progesterone values

Low values usually reflect reduced ovarian production after ovulation or absent ovulation altogether. In menstruating women, this often signals anovulatory cycles or a weak luteal phase, which can affect menstrual regularity, fertility, and premenstrual symptoms. In pregnancy, low progesterone may indicate inadequate support for the uterine lining or early pregnancy complications. In men and postmenopausal women, progesterone is naturally very low and has limited clinical significance.

Optimal progesterone values

Being in range suggests healthy ovulation and adequate corpus luteum function in the second half of the menstrual cycle. Optimal values depend heavily on timing - progesterone should be low in the follicular phase and rise significantly after ovulation during the luteal phase. In pregnancy, rising progesterone supports implantation and placental development. Optimal levels reflect balanced reproductive hormone signaling and stable endometrial support.

High progesterone values

High values usually reflect normal pregnancy, ovulation, or exogenous hormone use such as progesterone supplementation or certain contraceptives. Rarely, elevated progesterone may occur with ovarian cysts or adrenal tumors that produce steroid hormones. Persistent elevation outside of pregnancy or supplementation warrants further investigation.

Factors that influence progesterone interpretation

Progesterone fluctuates dramatically across the menstrual cycle, so timing of the blood draw is critical for accurate interpretation. Pregnancy, hormone therapy, and certain medications all raise levels. Lab methods vary, and single measurements provide limited information without clinical context.
