Fertility tests for women: what is included, and what it costs.

There is no single fertility test. For women, checking fertility usually means a blood panel that measures ovarian reserve and the hormones running your cycle, sometimes a pelvic ultrasound, and a semen analysis for a male partner. Blood tests tell you a lot, but they cannot tell you whether you will conceive.

What "fertility test" means for women (there is no single test)

Most people picture one result with one answer. Fertility does not work that way. It depends on how many eggs you have left, whether you release one each month, whether the hormones driving that are in balance, whether the sperm side is healthy, and whether the anatomy lets the two meet.

Different tests answer different parts of that. A blood panel answers the hormone and reserve questions well. An ultrasound answers the structural ones. A semen analysis answers the male half. Put together they give you a picture; no one of them gives you a verdict.

Fertility testing tells you where you are starting from and flags anything that needs attention. It does not predict the future. Plenty of women with reassuring results take time to conceive, and plenty with a flagged result conceive without help.

The blood tests: what each marker actually answers

A standard female fertility blood panel in Australia covers six markers in one early-cycle collection, plus a separately timed progesterone, and each one has a specific job. Some are timed to your cycle, some can be taken any day.

Marker	What it answers	When it is collected
AMH	How large your remaining egg supply is (ovarian reserve). The best predictor of response to IVF stimulation. Says nothing about egg quality.	Any day
FSH	How hard your brain is working to recruit a follicle. A rising FSH is a later signal than a falling AMH.	Day 2 to 5
LH	Read against FSH. A high LH to FSH ratio is one pattern seen in PCOS; a surge triggers ovulation.	Day 2 to 5
Oestradiol	The main oestrogen. Measured with FSH because a high oestradiol pushes FSH down and can make reserve look better than it is.	Day 2 to 5
Prolactin	A common and correctable reason for cycles becoming irregular or stopping. Raised prolactin can switch off ovulation.	Any day, rested
TSH	Thyroid function. Under-active and over-active thyroid both affect cycles, ovulation and pregnancy.	Any day
Progesterone	Whether you actually ovulated this cycle, rather than inferring it from other markers.	7 days after ovulation

Ranges vary by laboratory; your report shows the range your lab uses. Typical ranges on this page are drawn from Pathology Tests Explained (RCPA) and the sources listed below.

Progesterone sits apart because of its timing: the day 2 to 5 markers come from one collection at the start of a cycle, while progesterone needs a second in the second half. That is why it is offered separately as an ovulation check, and the day 21 progesterone test article explains how to time it if your cycle is not 28 days.

Some panels add testosterone where PCOS is suspected, or iron studies where periods have been heavy. Those are add-ons rather than core fertility markers.

Ultrasound and tubal tests: what a blood test cannot do

This is where honesty matters. A blood test cannot see your ovaries, your uterus or your fallopian tubes, and some of the most common reasons for difficulty conceiving are structural.

• Pelvic ultrasound looks at the uterus and ovaries. It can show fibroids, polyps, ovarian cysts and the polycystic ovarian appearance that forms part of a PCOS assessment.
• Antral follicle count is done during that ultrasound early in the cycle. It counts the small follicles visible on each ovary, a direct look at the same pool AMH reflects. When the two agree, a doctor can be confident about where reserve sits.
• Tubal patency tests such as an HSG or HyCoSy check whether the fallopian tubes are open. These are arranged through a specialist or radiology practice.
• Laparoscopy is a surgical look inside the pelvis, used when endometriosis or adhesions are suspected. It sits well outside anything a blood test covers.

KnowLuna does not provide imaging or procedures. If your results or your history point that way, the doctor reviewing your report will say so and explain who to see next.

When to test: trying now, planning later, or just curious

The right time to test depends on which of these you are.

• You are trying now and it has been a while. The usual advice in Australia is to seek review after 12 months of trying if you are under 35, and after 6 months if you are 35 or over. Testing earlier is reasonable if your cycles are irregular or absent, or if you have a known condition such as PCOS or endometriosis.
• You are planning in the next year or two. A baseline panel is most useful here, because there is still time to act on what it shows. This is also the point to think about a preconception check, which covers immunity status, blood group, iron, vitamin and thyroid markers rather than fertility hormones.
• Children are a "maybe, later" question. A low result for your age may make you bring a decision forward; a normal one is not permission to wait indefinitely, because age still drives egg quality.
• Your cycles have changed. Irregular, very long, very short or absent periods are a reason to test regardless of whether you want children now. See irregular periods and what to test.
• You are on hormonal contraception. The pill, the ring, the injection and the implant suppress FSH, LH and oestradiol, and combined methods can lower AMH readings too. A hormonal IUD has much less effect on these markers. Results are still worth having, but need reading with that in mind.

Cost with a referral compared with self-pay

Some hormone markers attract a Medicare rebate when a GP requests them for a recognised clinical reason, which usually means you have been trying for a while or have symptoms. AMH has no item number on the Medicare Benefits Schedule, so it does not attract a rebate in any setting, even when a GP orders it, and it is paid for privately either way.

That leaves three practical routes:

• Through your GP. Rebated markers cost you little or nothing; AMH is an out-of-pocket add-on. You need an appointment, and rebates depend on meeting the clinical criteria.
• Through a fertility clinic. Thorough, and the right place if you are moving towards treatment, but generally the longest wait and the highest cost for a baseline.
• Self-pay pathology. A flat price, your own timing, no referral step. Prices vary between providers, so compare which markers are included before comparing numbers.

The AMH and fertility panel covers AMH, FSH, LH, oestradiol, prolactin and TSH in one collection. It is $179 if you bring a signed request from your own doctor, or $259 if a KnowLuna women's health doctor reviews a short questionnaire, requests the panel and explains the results in a 20-minute video consult. The ovulation check is $59 as a single test, with an optional consult add-on of +$59. Collection is at accredited (NATA and RCPA) centres around Australia.

KnowLuna is self-pay with no Medicare rebate, and we say so plainly rather than burying it. If a rebated pathway through your GP suits you better, take it. The hormone test cost article compares the routes in more detail.

Reading results as a picture, not a verdict

These markers are read together. A number that looks alarming in isolation often means very little once the others are on the page.

• A low AMH with normal FSH, regular cycles and confirmed ovulation is a planning signal, not a problem. Women with low AMH conceive naturally at broadly similar rates to those with normal AMH over a year of trying.
• A high AMH with a raised LH to FSH ratio and irregular cycles is a pattern that points towards PCOS, which a doctor assesses formally against the diagnostic criteria rather than from bloods alone.
• A raised prolactin can suppress ovulation and is often the reason an otherwise normal-looking panel comes with absent periods. It is usually repeated first, because a single reading can be lifted by stress or a recent meal.
• A borderline TSH matters more when you are trying to conceive than at other times, which is why thyroid belongs in a fertility panel.
• A low day 21 progesterone may mean you did not ovulate that cycle, or simply that the test was mistimed. Timing is checked before conclusions are drawn.

Your KnowLuna report explains each marker in plain English against the laboratory's range, and anything abnormal is followed up by an AHPRA-registered doctor. Nothing is left as a number you have to interpret alone.

The partner side: semen analysis

If there is a male partner, testing one of you is testing half the question. A male factor is involved in roughly half of couples who have difficulty conceiving, and a semen analysis is the most informative test for it.

It measures volume, concentration, motility and morphology. Preparation is 2 to 5 days without ejaculation, and the sample is produced at or delivered to a participating centre within about an hour, because the measurements change quickly outside the body. Results vary between samples, so a flagged result is usually repeated before it is acted on.

The semen analysis is $89 and needs no cycle timing. Doing it alongside her blood panel saves months, because the alternative is testing one partner, waiting, then testing the other. The semen analysis cost article covers what to expect on the day.
