What are Female Infertility biomarkers

Female infertility biomarkers are blood signals that reveal how the reproductive system is functioning. They turn the cycle’s hidden rhythms into a readable map of egg supply, ovulation, and hormone coordination. Ovarian reserve is reflected by a follicle‑derived hormone that mirrors the remaining egg pool (anti‑Müllerian hormone, AMH). Brain‑to‑ovary messengers drive follicle growth and the ovulatory surge (follicle‑stimulating hormone, FSH; luteinizing hormone, LH). Ovarian hormones show follicle maturation and luteal activity (estradiol, E2; progesterone). Thyroid and lactation hormones influence ovulation and cycle regularity (thyroid‑stimulating hormone, TSH; prolactin). Androgen and metabolic markers point to hormone excess or insulin effects that can disrupt ovulation (testosterone, DHEA‑sulfate, sex hormone–binding globulin, insulin). Reviewed together, these tests create a functional picture of the hypothalamic–pituitary–ovarian axis and its modifiers, clarifying where signals may be mistimed or opposed. The result is practical: biomarker testing makes the physiology visible, so care can target the right step—diagnosis, cycle timing, and treatment planning.

Why is blood testing for Female Infertility important?

• Understand why getting pregnant is hard by checking key reproductive hormone signals.
• Spot ovulation problems by confirming progesterone rise and a coordinated LH–FSH response.
• Flag diminished ovarian reserve with high day-3 FSH or elevated estradiol levels.
• Clarify polycystic ovary syndrome risk when LH exceeds FSH and cycles are irregular.
• Explain missed periods or unexpected lactation by checking prolactin for pituitary causes.
• Guide thyroid care to protect ovulation and early pregnancy by measuring TSH.
• Protect implantation by identifying estrogen–progesterone imbalance that can thin the uterine lining.
• Track treatment success and cycle timing by repeating tests on targeted cycle days.

What insights will I get?

Female infertility blood testing provides a window into the hormonal systems that govern not only reproduction, but also energy balance, metabolism, and overall endocrine health. At Superpower, we measure six key biomarkers—FSH, LH, Estradiol, Progesterone, Prolactin, and TSH—to map the hormonal signals that orchestrate the menstrual cycle and fertility. These hormones interact in a finely tuned network, influencing ovarian function, egg maturation, and the ability to conceive.

FSH (follicle-stimulating hormone) and LH (luteinizing hormone) are pituitary hormones that regulate the growth and release of eggs from the ovaries. Estradiol, a form of estrogen, is produced by the ovaries and signals the readiness of the reproductive system. Progesterone, also from the ovaries, prepares the uterine lining for implantation. Prolactin, another pituitary hormone, primarily controls milk production but can also affect ovulation. TSH (thyroid-stimulating hormone) reflects thyroid function, which is closely linked to menstrual regularity and fertility.

Balanced levels of these hormones support stable menstrual cycles, healthy ovulation, and optimal conditions for conception. Disruptions—such as elevated FSH or prolactin, low estradiol or progesterone, or abnormal TSH—can signal underlying issues with ovarian reserve, ovulation, or thyroid health, all of which can contribute to infertility.

Interpretation of these biomarkers depends on factors like age, menstrual phase, pregnancy status, recent illness, medications, and laboratory methods. These variables can influence hormone levels and should be considered when evaluating results.
