What does the Progesterone test measure?

Q: Why is Progesterone measured?

Mid-luteal progesterone measurement confirms ovulation and adequate corpus luteum function. Low luteal values suggest anovulation or luteal-phase deficiency, a contributor to infertility and early pregnancy loss. Elevated progesterone outside the luteal phase or pregnancy may indicate adrenal hyperplasia or an ovarian tumour.

Q: What is the reference range for Progesterone?

The standard reference range for Progesterone is Follicular phase <1 ng/mL, mid-luteal phase 5–20 ng/mL in ovulatory cycles; males and postmenopausal females <1 ng/mL; method-specific.. Reference ranges vary by laboratory and assay platform — interpret in context of the issuing laboratory's stated range.

Progesterone (P4) is a clinical biomarker used in male-hormones assessment. Progesterone is secreted by the corpus luteum after ovulation and by the placenta during pregnancy. It is measured in 1 laboratory test on BiomarkersLabs.com.

Reference Range: Follicular phase <1 ng/mL, mid-luteal phase 5–20 ng/mL in ovulatory cycles; males and postmenopausal females <1 ng/mL; method-specific.
Units: ng/mL, nmol/L
Measured In: 1 test
Category: Male Hormones

Functional medicine optimalIn an ovulatory cycle, mid-luteal progesterone above 5 ng/mL is typically considered evidence of ovulation; values above 10 ng/mL indicate robust luteal function. Follicular-phase and male reference values should remain below 1 ng/mL.

What is Progesterone?

Progesterone is secreted by the corpus luteum after ovulation and by the placenta during pregnancy. In the luteal phase of the menstrual cycle it prepares the endometrium for implantation and modulates immune and inflammatory pathways. Small amounts are synthesised by the adrenal cortex in both sexes and serve as a precursor for other steroid hormones.
