Fertility is one of the few areas of health where waiting has a real cost, and also one where people wait the longest — often because they don't know what a check actually involves or worry about what they'll be told. A first fertility assessment is mostly a blood test and an ultrasound, and knowing your baseline is useful whether you're trying now or thinking about later.
When a check is worth doing
The standard guidance is straightforward, and it's based on age because that's what changes the timeline:
- Under 35 — after about twelve months of trying without success.
- 35 and over — after about six months, since waiting longer narrows the options.
- Sooner than either, if you have irregular or absent periods, known PCOS or endometriosis, previous pelvic surgery or infection, or you're over 40.
There's also a reason to come in before you start trying at all: if something needs treating — a thyroid problem, an untreated infection, irregular ovulation — it's easier to address before you're counting months.
What the check involves
A first assessment is less involved than most people expect. The usual components:
| Test | What it looks at |
|---|---|
| AMH blood test | ovarian reserve — roughly, how many eggs remain |
| Hormone panel | FSH, LH, estradiol, thyroid, prolactin |
| Pelvic ultrasound | uterus, ovaries, and the antral follicle count |
| Cycle review | whether and when you're ovulating |
| Tubal check | whether the fallopian tubes are open — added when indicated |
| Partner semen analysis | essential, and often skipped |
What AMH does and doesn't tell you
AMH is the test people fixate on, and it's the one most often misread. It estimates how many eggs remain — not their quality, and not whether you can conceive.
- A low AMH does not mean you can't get pregnant. It suggests a smaller reserve, which matters most for how you'd respond to IVF stimulation.
- A high AMH is not a guarantee. It can also accompany PCOS, where ovulation is the actual issue.
- Age still predicts egg quality better than any blood test. AMH says how many; age says more about how well.
A result is useful as one input into a plan, not as a verdict. If a number frightens you, ask what it changes about your options — often the answer is less than you feared.
What happens after the results
Most people are surprised how much happens before anything high-tech is considered:
- Timing — confirming when you ovulate and aiming for it is the simplest intervention, and it resolves a meaningful share of cases.
- Treating what's found — thyroid problems, irregular ovulation, infections and fibroids are addressed first if present.
- Ovulation induction — medication to encourage a regular ovulation, often used when cycles are irregular.
- Referral onward — IUI and IVF are done at a specialist fertility centre, and your clinic can refer you with your workup already complete.
A women's clinic is the right place for the first steps. If you end up needing a specialist centre, arriving with tests already done saves you repeating them.
Getting checked in Korea, in English
Korea has strong fertility care and short waiting times by international standards. The practical distinction is between a women's clinic, which does assessment and first-line treatment, and a fertility centre, which does IUI and IVF.
On cost: investigation of a medical problem is generally covered by National Health Insurance, while elective screening of your fertility status often isn't. Ask which applies before the tests are run.
This is a subject where language matters more than usual. Results come as numbers that are easy to misread, and the decisions that follow — how long to keep trying, whether to escalate — depend on understanding what each figure actually means for you. Having that explained properly in English is worth choosing a clinic for.
Common questions
How long should we try before getting checked?
About twelve months under 35, about six months at 35 and over. Come sooner if your cycles are irregular, you have a known condition, or you're over 40.
Does a low AMH mean I can't have children?
No. AMH estimates how many eggs remain, not whether you can conceive. Many women with low AMH conceive. It matters most for predicting response to IVF stimulation.
Should my partner be tested too?
Yes, from the start. Male factors account for a large share of cases, and a semen analysis is quick. Testing only one partner is how a workup loses months.
Do I need a fertility centre, or is a clinic enough?
A women's clinic handles assessment and first-line treatment, which resolves many cases. IUI and IVF are done at a specialist centre, and you can be referred with your tests already complete.
Can I be seen in English?
Yes. At Ium a female OB-GYN specialist explains the tests, what each result means for you, and the options — in English, without rushing.
