Female Hormone Levels: Which Hormone Levels to Test and When

Again and again, I encounter concerned patients who bring a single lab sheet, a marked value, and great worry. "My estrogen is too low, isn't it?" And often my first question is not how high the value is, but: On which cycle day was it measured? Because that precisely determines whether the number means anything at all.

A woman's hormone status is not a single value, but an interplay of many messenger substances that constantly shift throughout the cycle. This overview categorizes the most important values: what they are, what each of them indicates, when you should measure them in the cycle, and what their limitations are. This way, you go into your next conversation with understanding, not just a single number.

What is a hormone status in women?

A hormone status is the targeted measurement of several hormones in the blood that collectively describe your hormonal situation. No lab measures "the one" hormone, but a pattern: reproductive hormones, androgens, prolactin, and the thyroid gland only together provide a meaningful picture.

For example, in cases of irregular cycles and signs like increased body hair, the doctor looks not just at one value, but at the pattern of LH, FSH, testosterone with SHBG, and possibly DHEAS, to differentiate PCOS from other causes. In suspected perimenopause, on the other hand, a rising FSH level early in the cycle is more indicative than a single estradiol measurement. The pattern counts, not the individual number.

Such a determination becomes useful when there is a specific suspicion or question behind it: an irregular or absent cycle, unfulfilled desire to conceive, indications of PCOS, the transition to menopause, or suspicion of a thyroid disorder. A hormone status is then a tool for orientation that complements, not replaces, your symptoms. The interpretation of the values always belongs to a doctor, because the same number can be read completely differently depending on the life stage, cycle day, and symptom profile.

Which hormone levels matter, and when you should measure them

The relevant values can be organized into three groups: reproductive hormones (FSH, LH, estradiol, progesterone, AMH), androgens (testosterone, free testosterone, SHBG, DHEAS), as well as prolactin and thyroid values as important co-factors. The following table provides an overview of when to measure which value and what it indicates.

Hormone value	When to measure	What it indicates
FSH (follicle-stimulating hormone)	Cycle day 2 to 5	Ovarian function and egg reserve; rises during the transition to menopause.
LH (luteinizing hormone)	Cycle day 2 to 5 (basal value)	Controls ovulation; the LH-to-FSH ratio can be abnormal in PCOS.
Estradiol	Cycle day 2 to 5 (basal value)	Most important estrogen; reflects egg maturation and cycle phase.
Progesterone	Mid-luteal phase, approx. 7 days before period	Confirms ovulation; indicates corpus luteum function.
Testosterone (total and free) + SHBG	Morning, early in cycle	Androgen status; SHBG binds sex hormones and co-determines the free fraction.
AMH (Anti-Müllerian hormone)	Cycle-independent, any day	Marker for egg reserve (ovarian reserve).
Prolactin	Morning, fasting and rested	Influences the cycle; can be elevated in cycle disorders or fertility issues.
TSH (+ fT3, fT4, TPO-Ab)	Cycle-independent	Thyroid function; strongly affects cycle and fertility.
DHEAS	Cycle-independent, morning	Adrenal androgen; helps to classify the source of elevated androgens.

The reproductive hormones tell the story of the cycle: FSH and LH control the ovaries from the pituitary gland, estradiol rises with the maturing egg, and progesterone from the corpus luteum characterizes the second half of the cycle. A high basal FSH value or a low AMH indicates a decreasing egg reserve, while an abnormal LH to FSH ratio can be associated with PCOS.

The androgens and their co-factors complete the picture: testosterone and DHEAS show the androgen status, with DHEAS primarily originating from the adrenal gland and helping to pinpoint the source of elevated levels. SHBG co-determines how much testosterone is freely available. Finally, prolactin and thyroid values have an indirect but strong effect: elevated prolactin or an out-of-sync thyroid can inhibit ovulation and make periods irregular. It is precisely such indirect chains, from a single value through a mechanism to a noticeable cycle change, that make a complete hormone status so valuable.

How to interpret individual values in detail is shown in the respective reference tables: for example, for your estradiol value and your progesterone value. These detailed pages belong to this overview and each delve deeper into a single marker.

When to measure in the cycle? Timing is key

The correct measurement time for a hormone status is almost as important as the value itself. Because reproductive hormones fluctuate greatly throughout the cycle, a value is only comparable if it was taken during the appropriate phase.

Early in the cycle, i.e., on day 2 to 5 after the start of bleeding, you measure the basal values of FSH, LH, and estradiol. In this early follicular phase, the values are low and stable, making this window suitable for assessing the baseline ovarian function. A high basal FSH value, for example, can indicate declining egg reserve or the transition to menopause. You can find more details in the article on FSH values.

Progesteronebelongs in the second half of the cycle. The mid-luteal phase is most informative, which is around 7 days before the expected period. In a classic 28-day cycle, this is around day 21; for longer or shorter cycles, the date shifts accordingly. Therefore, it is better to count backward from the expected bleeding than forward from the last period. A sufficiently high value indicates that ovulation has occurred. Because progesterone is released in pulses, a borderline result is more likely to be repeated than immediately evaluated.

Androgenssuch as testosterone and DHEAS are best determined in the morning when levels are highest and most comparable; for testosterone, the early follicular phase is also preferred. Since a large portion of testosterone is bound to SHBG, the total value alone is not very informative. Only in conjunction with SHBG can the biologically active, free portion be estimated (Rosner et al., 2007).

Prolactinis sensitive to stress, sleep, physical exertion, and even the blood draw itself. Therefore, it is determined in the morning, on an empty stomach, and at rest. AMH, TSH, and DHEAS, however, fluctuate little throughout the cycle and can be measured on any day. AMH is considered a robust marker of ovarian reserve, although more recent studies show that it fluctuates more than long assumed (ASRM, 2020).

Blood, saliva, or urine: what is really informative?

For a classic hormone status, blood is the best-studied and most widely accepted method. Most reference values used by doctors are based on serum determinations from blood.

The blood testmeasures the concentration of a hormone in the serum and is the standard for FSH, LH, estradiol, progesterone, testosterone, SHBG, AMH, prolactin, and thyroid values. It is well-standardized and provides the numbers on which established reference ranges are based.

The saliva testprimarily detects the free, unbound portion of a hormone. A useful application is the cortisol diurnal profile, where several saliva samples throughout the day reflect the natural course, which is difficult to achieve with a single blood draw. For sex hormones, however, saliva measurement is less standardized, and the results cannot be directly translated to blood reference values.

The urine test, often through a 24-hour collection or as dried urine, can reflect hormones and their metabolites over a longer period. This is interesting for specific questions and in research, such as for metabolite ratios, but it does not replace established blood diagnostics in routine practice. In short: For most questions regarding hormone status, blood remains the reference, while saliva and urine have their place for clearly defined special questions.

How to prepare for a hormone test

A few small things determine how reliable your values are. First, note your cycle day, because without this information, FSH, LH, estradiol, and progesterone can hardly be interpreted. Schedule the blood draw for the morning if possible, as many hormones follow a diurnal rhythm, and arrive rested for prolactin, as stress and the journey to the practice can temporarily elevate the value.

Also, tell your doctor which medications or hormones you are taking, especially the pill, as hormonal contraception significantly shifts many values. How individual markers change under the pill can be found in the article Pill and Blood Values. A frequently overlooked point is high-dose biotin supplements: biotin can falsify common lab tests and make thyroid or hormone values appear falsely high or low (FDA, 2019). Such preparations should be discontinued a few days before the measurement after consulting your doctor.

Limitations of a hormone panel: why a single value is rarely enough

A hormone panel provides a snapshot, not an absolute truth. Hormone levels fluctuate from day to day, throughout the menstrual cycle, and across different life stages, which is why a single number on its own says very little.

Only context makes a value interpretable: In which phase of the cycle was it measured? What life stage are you in, for example, perimenopause? What symptoms do you have, and does the pattern of multiple values fit? A low estradiol level on cycle day 3 is completely normal; the same number in the middle of the cycle would not be. This is precisely why a hormone panel is not a substitute for a diagnosis, and certainly not for a self-diagnosis from the internet.

Furthermore, a single abnormal value is rarely cause for panic. Because hormones are released in bursts, fluctuate from cycle to cycle, and can even be influenced by the blood draw itself, a borderline or unexpected result is usually repeated before conclusions are drawn. Only a repeatedly abnormal pattern that matches your symptoms is truly reliable.

You get the most out of your results when you interpret them together with a doctor who knows your symptoms, your cycle, and your medical history. A good overview of why testing is worthwhile at all and what regular check-ups offer can be found in the article Why Regular Blood Tests are Invaluable for Women.

Cervix and Cancer Screening: Pap Smear and HPV Test

Not all women's diagnostics revolve around hormones. A separate, equally important strand is cervical cancer screening with the Pap smear and the HPV test. Both are an integral part of gynecological diagnostics, even though they do not measure hormone levels.

In Germany, cervical cancer screening has been regulated as an organized program since 2020. Women aged 20 to 34 are entitled to an annual Pap smear. From age 35, co-testing with a Pap smear and HPV test is offered every three years (G-BA, since 2020). The Pap smear assesses cell changes and is classified into stages from Pap I to Pap V; the HPV test detects human papillomaviruses, which are the most important cause of these changes.

What the individual results mean and what steps are advisable are covered in more detail in the separate articles in this cluster, such as Pap test results from Pap I to Vor the further procedure if an HPV result is positive. More information on the official program can be found at the Joint Federal Committee.

Conclusion

A woman's hormonal status is not a single value, but a pattern of reproductive hormones, androgens, prolactin, and thyroid hormones that can only be interpreted at the right moment in the cycle. FSH, LH, and estradiol should be measured on days 2 to 5, and progesterone during the mid-luteal phase, while AMH, prolactin, TSH, and DHEAS can be determined on any day. Blood remains the reference method; saliva and urine have their place for specific specialized questions.

In the end, what counts is not the individual number, but its interpretation: together with your symptoms, your life stage, and a doctor's perspective. Use this overview as a map and go from here into the individual topics that currently concern you.

Frequently asked questions about female hormone levels

Which hormone levels should be tested?

A comprehensive hormone panel usually includes FSH, LH, and estradiol for ovarian function, progesterone to confirm ovulation, testosterone with SHBG and DHEAS for androgen status, AMH as a marker of ovarian reserve, prolactin, and thyroid values (TSH, and if necessary, fT3, fT4, and TPO-Ab). Which values are useful depends on your specific question and are best determined by a doctor.

When to measure hormones during the cycle?

You measure FSH, LH, and estradiol early in the cycle on days 2 to 5. Progesterone should be measured in the mid-luteal phase, approximately 7 days before the expected period; in a 28-day cycle, this is around day 21. AMH, prolactin, TSH, and DHEAS are largely cycle-independent and can be determined on any day, with prolactin ideally measured in the morning and at rest.

Blut- oder Speicheltest, was ist besser?

Für die meisten Fragen rund um den Hormonstatus ist der Bluttest die Referenz, weil er am besten standardisiert ist und die etablierten Referenzwerte darauf beruhen. Der Speicheltest erfasst den freien Hormonanteil und ist vor allem beim Cortisol-Tagesprofil sinnvoll. Für die Sexualhormone ist Speichel weniger standardisiert und nicht direkt mit den Blutwerten vergleichbar.

Was kostet ein Hormontest?

Die Kosten hängen davon ab, welche und wie viele Werte bestimmt werden. Einzelne Hormonwerte liegen als Selbstzahlerleistung oft im Bereich von etwa 20 bis 40 Euro, ein umfassender Status kann entsprechend höher liegen. Ist eine Bestimmung medizinisch begründet, kann sie von der Krankenkasse übernommen werden. Ein strukturiertes Diagnostik-Kit mit Einordnung bewegt sich je nach Umfang im dreistelligen Bereich.
