Hormone Panel for Women: Estrogen, Progesterone, and Fertility Markers

Quick answer

A full female hormone panel often includes estradiol, progesterone, FSH, LH, and prolactin. It also includes total and free testosterone, SHBG, DHEA-S, AMH for fertility, and morning cortisol. Cycle timing matters a lot. Some markers only make sense when drawn on a specific day of your cycle.

When to test: cycle timing matters

For women with regular periods:

• Day 3, early in your cycle: FSH, LH, estradiol, and AMH. These check your remaining egg supply and your pituitary's signal.
• Day 21, about a week before your period: progesterone. This confirms whether you ovulated.
• Any day: prolactin, testosterone, SHBG, DHEA-S, cortisol, and thyroid markers.

For irregular cycles or perimenopause, timing matters less. Test when it is convenient, and share your cycle history with your doctor.

For women who have gone 12 months or more without a period, cycle timing no longer applies.

The core markers

Estradiol (E2)

This is the main estrogen during your reproductive years. Before menopause, in the early part of your cycle, the standard range is 30 to 120 pg/mL. After menopause, it drops under 30 pg/mL. Estradiol drives your cycle. It also affects your bones, mood, skin, and blood vessels. Both very low and very high levels cause symptoms.

Progesterone

This hormone rises in the second half of your cycle. It confirms ovulation and supports an early pregnancy. On day 21, a result above 10 ng/mL confirms that you ovulated. Cycles without ovulation show low progesterone. This is common with PCOS, perimenopause, and stress.

FSH (follicle-stimulating hormone)

This is your pituitary's signal that drives egg development. On day 3, the standard range is 3 to 10 IU/L. After menopause, it rises above 25 IU/L. A rising day-3 FSH, above 10, is an early sign. It shows your egg supply is going down. Perimenopause may be getting closer.

LH (luteinizing hormone)

This is the pituitary signal that triggers ovulation partway through your cycle. On day 3, the standard range is 2 to 10 IU/L. An LH to FSH ratio above 2 to 1, on day 3, is a classic sign of PCOS. PCOS is a hormone condition. It affects ovulation.

AMH (anti-Müllerian hormone)

This shows your ovarian reserve. That means how many eggs you likely have left. Your level depends heavily on age. It peaks in your mid-20s. Then it declines steadily. AMH may be the single best blood marker of your fertility window. A low AMH at any age is worth knowing. A very low AMH in your 30s is worth acting on soon. Talk with a doctor about a fertility plan.

Prolactin

This is a pituitary hormone. When it runs high, it can stop ovulation. It can disrupt your cycle too. The standard range is under 25 ng/mL. High prolactin is a fixable cause of cycle problems. It is often tied to certain medicines.

Total and free testosterone

Testosterone matters for women too. It affects your sex drive, energy, mood, and muscle. The standard range for total testosterone in women is 8 to 60 ng/dL. Free testosterone runs much lower. High testosterone is part of the PCOS pattern. Low testosterone can add to low sex drive. It can add to fatigue too.

SHBG

This is the protein that binds to testosterone. The standard range is 18 to 144 nmol/L. It varies by age and by birth control use. Hormonal birth control raises SHBG a lot. This lowers your free testosterone. It can lower your sex drive too.

DHEA-S

This hormone comes from your adrenal glands. Your body uses it to build testosterone and estrogen. Your level depends heavily on your age. It runs very high in some women with PCOS. It runs low with chronic stress. It also runs low with aging.

Morning cortisol

The standard range for an 8 AM draw is 6 to 23 µg/dL. Chronic stress affects nearly every other hormone on this list.

Common patterns

Pattern 1: PCOS (polycystic ovary syndrome)

A day-3 LH to FSH ratio above 2 to 1. High total testosterone, free testosterone, or DHEA-S. Often high fasting insulin too. This is a key driver of PCOS. Often a high AMH. This pattern often comes with irregular cycles, acne, and extra hair growth.

Pattern 2: Perimenopause

A rising day-3 FSH, above 10, that often climbs further over time. Estradiol becomes more unpredictable. AMH drops. Progesterone often stays low, even in cycles that still look regular. Symptoms include irregular cycles, poor sleep, mood changes, and hot flashes.

Pattern 3: Postmenopause

FSH above 25, no matter the day. Estradiol under 30 pg/mL. AMH too low to detect. Testosterone slowly declining.

Pattern 4: Functional hypothalamic amenorrhea

This means your periods stop because your brain slows its hormone signals. Low estradiol. Low LH and FSH. Often linked to eating too little, exercising too much, or severe stress. Often fixed once you eat enough and rest more.

Pattern 5: High prolactin

Prolactin often above 50 ng/mL. Low FSH and LH. Irregular periods or periods that stop. Causes include certain medicines, stress, or rarely, a small pituitary growth.

Pattern 6: High androgens

High total or free testosterone. Sometimes high DHEA-S. Symptoms include extra hair growth, acne, and thinning scalp hair. Common in PCOS, but worth checking for other causes too.

When women should test

• A yearly baseline for adult women starting in their late 20s.
• Fertility planning: AMH, day-3 FSH, LH, and estradiol, day-21 progesterone, prolactin, thyroid, and vitamin D.
• Cycle problems: a full panel plus prolactin and thyroid.
• Suspected PCOS: a full panel plus fasting insulin, glucose, and a cholesterol panel.
• Perimenopause symptoms: day-3 FSH and estradiol, AMH, and a full panel.
• Low sex drive or ongoing fatigue: testosterone, SHBG, DHEA-S, thyroid, and cortisol.
• After menopause: baseline FSH, estradiol, vitamin D, cholesterol, and bone health markers.

How thyroid and metabolic health connect to female hormones

Female hormones do not work alone. Thyroid problems often show up first as cycle irregularity. Insulin resistance is a major driver of PCOS. Low vitamin D makes both worse. Low iron can feel just like perimenopause fatigue. A real check of any hormone complaint often includes:

• A full thyroid panel (TSH, Free T3, Free T4).
• Metabolic markers (HbA1c, fasting insulin, glucose, cholesterol).
• Vitamin D, B12, and ferritin.

This is why "just check my hormones" is rarely the full picture.

How a &you Labs report handles this

A &you Labs panel for women covers estradiol, progesterone, FSH, LH, and prolactin. It also covers testosterone, SHBG, DHEA-S, and cortisol. AMH gets added for fertility questions. Every result comes with the standard lab range and the healthy target range side by side. A doctor's written interpretation takes your cycle timing into account too.

Frequently asked questions

Should I test while on hormonal birth control?

You can, but the results read differently. Birth control lowers your body's own FSH, LH, estradiol, and progesterone. It also raises SHBG a lot. AMH and prolactin still mean something useful. Tell your doctor if you are on hormonal birth control before you test.

When should I test for fertility planning?

Day 3 of your cycle works best for FSH, LH, estradiol, and AMH. AMH stays fairly stable through your cycle. It can be drawn on almost any day if timing is hard to manage.

Is AMH a reliable fertility predictor?

AMH is the best single blood marker of your egg supply. It does not perfectly predict whether you will conceive. Many women with low AMH still get pregnant. Some with normal AMH struggle. It is one piece of the picture, along with your age and other markers.

Can perimenopause start in my 30s?

Yes. Doctors increasingly recognize early perimenopause. Some women see irregular cycles and rising FSH in their late 30s. A baseline panel before age 40 is a useful reference point.

What should I test if I am on hormone replacement therapy?

Your estradiol level should be checked to confirm your dose is right. This matters especially with patches or gels. The exact markers to watch depend on your specific treatment. Talk with the doctor managing your care.

Key takeaways

• Reading a female hormone panel correctly means paying attention to cycle timing.
• A full panel includes estradiol, progesterone, FSH, LH, and prolactin. It also includes testosterone, SHBG, DHEA-S, AMH, cortisol, and thyroid and metabolic markers.
• Common patterns to know include PCOS, perimenopause, postmenopause, hypothalamic amenorrhea, and high prolactin.
• AMH is the best single marker of egg supply. Day-3 FSH catches perimenopause early.
• Hormone problems rarely stand alone. Thyroid, insulin, vitamin D, and iron all play a part.
