Fertility Assessment in China

Plan a fertility work-up in China with concurrent partner assessment, targeted ovarian, tubal and semen tests, realistic timing and cross-border result checks.

Key takeaways

Skip the arbitrary waiting period when age, irregular or absent periods, known tubal or uterine disease, endometriosis, previous gonadotoxic treatment, sexual dysfunction or suspected male-factor infertility already tells you time matters.[1][2]
Sperm and eggs come from two people, so the evaluation should run on two people at once. Nobody needs to finish a full battery of tests before the other partner is even examined.[2][3]
A useful core work-up answers three questions: Is ovulation occurring? Are the uterus and tubes suitable for the intended route to pregnancy? Is sperm production and delivery adequate? Which tests that takes depends on the history and the planned treatment.
AMH and antral follicle count mainly estimate the ovarian response to stimulation. Neither one measures egg quality, and neither should be used alone to pronounce someone fertile or infertile.[2]
One abnormal semen analysis is a finding to confirm, not a finished diagnosis. Collection conditions, recent illness, the abstinence interval, transport and the laboratory's method can all move the numbers.[3][4]
Be wary of a large “fertility panel” where nobody can explain how each result would change the plan. Routine laparoscopy, postcoital testing, endometrial biopsy, immune or thrombophilia panels, karyotyping and sperm DNA-fragmentation testing do not belong in every first evaluation.[2][3]

Full guide

A good fertility assessment starts small on purpose. History, examination and a short list of high-yield tests are there to settle one decision: keep trying, fix a medical problem, look deeper at one system, try ovulation induction or insemination, go to IVF, preserve fertility, or see a genetic counsellor. The work-up grows only when an early finding or the planned treatment gives it a reason to.

WHO notes that infertility can come from male factors, female factors or factors nobody can yet explain.[1] Used properly, “unexplained” means a sound basic evaluation found no cause. It should never become a cover for one partner going unexamined or a standard test getting skipped.

Know when the clock starts—and when it should not control the decision

For couples having regular unprotected intercourse, the usual trigger is 12 months of trying when the egg-providing partner is under 35, and six months from age 35 onward. Past 40, assessment often makes sense right away.[2][5]

Those timelines go out the window when there is:

no menstrual period, markedly irregular cycles or repeated bleeding between periods;
known or suspected endometriosis, tubal disease, uterine abnormality or prior pelvic infection;
an ectopic pregnancy, pelvic surgery or ovarian surgery in the past;
chemotherapy, pelvic radiation or another fertility-threatening treatment;
known genetic risk or a need for fertility preservation;
erectile, ejaculatory or sexual-function difficulty;
previous testicular injury, undescended testis, genital surgery or suspected sperm problem; or
recurrent pregnancy loss, which needs its own dedicated pathway instead of another pass through a generic infertility panel.

Anyone using donor sperm, reciprocal IVF or another route has no obligation to “try for 12 months” first. The work-up is built around the planned route and around whoever will supply the eggs, the sperm or the pregnancy.[2]

Start with a chronology, not a bag of laboratory reports

Before the first appointment in China, put together a one-page reproductive timeline: when you started trying, how often and how sperm exposure happens, pregnancies and how they ended, cycle length and how much it varies, pelvic or testicular symptoms, infections, operations, contraception and every previous treatment. For earlier treatment cycles, write down drug names, dates and doses, follicle counts, eggs retrieved, and fertilisation and embryo outcomes. “IVF failed” on its own tells the new team almost nothing.

Write down every medicine and supplement. Testosterone and anabolic steroids can shut down sperm production, and some cancer, psychiatric and other treatments affect reproductive function. Keep taking prescribed medicine unless the prescribing clinician says otherwise — the point is to make the exposure visible, not to self-adjust.

Bring the original reports in their source language along with translations. For ultrasound and hysterosalpingography, get the images too, since the written report alone leaves a lot out. For semen analysis, keep the collection instructions, collection time, abstinence interval, whether the full sample was captured, time to analysis and the laboratory's reference information. A translated summary stripped of methods is usually impossible to compare against new results.

Assess the egg-providing and pregnancy-carrying patient by clinical question

The first visit covers age, the menstrual and ovulation pattern, pregnancy history, pelvic pain, abnormal bleeding, infections, surgery, family history, endocrine symptoms and the physical findings. Tests come after, each one tied to a question that came up.

Ovulation. A long history of reliably regular cycles is decent evidence of ovulation by itself. With irregular or absent cycles, the job is to find the cause — ordering a “day 21 progesterone” over and over without adjusting for cycle length answers nothing. Thyroid testing earns its place when thyroid disease could impair fertility; prolactin is indicated with galactorrhoea, oligomenorrhoea or amenorrhoea and otherwise left alone.[2]

Ovarian reserve. AMH can be drawn on most cycle days, antral follicle count is done by transvaginal ultrasound, and early-follicular FSH and estradiol occasionally add context. What these tests do best is estimate how the ovaries are likely to respond to stimulation; natural conception is something they predict poorly. Age still carries most of the information about reproductive potential and egg-related chromosome risk. Low AMH does not put the chance of unassisted pregnancy at zero, and high AMH promises neither healthy eggs nor a live birth.[2][6]

Uterus and ovaries. Transvaginal ultrasound picks up fibroids, adenomyosis, ovarian cysts and other anatomy. When the cavity itself is in question, saline-infusion sonography or hysteroscopy come into play. Hysteroscopy looks directly and can treat selected intrauterine lesions in the same sitting; that still does not make it an automatic first test for everyone.[2]

Tubal patency. Where open tubes matter — natural conception or insemination — hysterosalpingography or an ultrasound-based contrast test does the job. The report should name each tube, describe the spill and flag any hydrosalpinx. If the planned pathway bypasses the tubes altogether, patency testing can often be skipped, unless a tubal lesion would itself interfere with treatment. Diagnostic laparoscopy stays out of the routine work-up unless symptoms, abnormal imaging or another specific indication calls for it.[2]

Assess sperm production and delivery in parallel

The AUA/ASRM guideline calls for a reproductive history plus one or more semen analyses as the initial male evaluation, with both partners assessed at the same time.[3] That history covers puberty, any previous paternity, genital infections and surgery, undescended testes, torsion or trauma, cancer treatment, recent fevers, medicines, testosterone or steroid use, occupational heat or toxin exposure, sexual function and family history.

A semen analysis goes well beyond a sperm count: volume, concentration, total number, motility and morphology, plus other findings where relevant. WHO publishes its sixth-edition laboratory manual precisely so results can be standardised and compared between laboratories.[4] The reference limits mark a rough zone in which fertile and infertile values overlap considerably; results also vary biologically, so they only make sense read against the couple's history.

When a result comes back abnormal, ask whether it should be repeated under controlled collection conditions, and when. A recent high fever or a partly missed collection can skew everything. Persistent abnormalities, azoospermia, very low concentration, examination findings or endocrine symptoms open the door to a male-reproductive specialist, hormone testing, genetic testing or targeted imaging — with the indication written down. Routine scrotal or transrectal ultrasound and routine sperm DNA-fragmentation testing are not first-line tests for every patient.[3]

Separate core tests from conditional tests

The single most useful question in the room is: What decision changes if this result is normal, abnormal or inconclusive? A test with no answer to that is probably being done too early.

Where the history points, conditional tests earn their keep:

genetic carrier testing or karyotype for a defined family history, recurrent loss, ovarian insufficiency, azoospermia or severe sperm abnormality;
androgen, 17-hydroxyprogesterone or metabolic assessment with signs of hyperandrogenism or PCOS;
prolactin with galactorrhoea or ovulatory disturbance;
targeted infection testing based on symptoms, exposure and treatment requirements;
pelvic MRI for a defined anatomical or endometriosis question; and
hysteroscopy or laparoscopy when imaging, symptoms or a planned intervention supplies an indication.

ASRM, for its part, puts laparoscopy for unexplained infertility, advanced sperm-function testing, postcoital testing, thrombophilia testing, immune testing, routine karyotype, endometrial biopsy and routine prolactin on the list of tests nobody should order at a first evaluation without a specific indication.[2] The 2026 NICE guideline takes the same line on routine sperm DNA-integrity testing and postcoital cervical-mucus testing.[7] If a clinic repackages low-evidence add-ons as a mandatory “international patient package,” treat that as a warning sign.

Use a staged timetable rather than promising a one-day diagnosis

A single visit can absorb many first-line tests; a complete answer may still span more than one cycle or call for repeat samples.

Before travel: have a clinician review your records; confirm which existing results the centre will accept; note the cycle day, expiry window and laboratory method for each; and book the reproductive-medicine appointment plus any indicated male-reproductive assessment on dates that fit together.

First clinical contact: both histories, examination where appropriate, a medication review, pregnancy testing when relevant and a preliminary problem list. Expect the clinician to say plainly what can already be concluded and what is still open.

Cycle-dependent window: early-cycle ultrasound and certain hormones only mean something at specific times. Tubal or cavity testing gets scheduled around the centre's infection and cycle protocol and to avoid an existing pregnancy. Anyone quoting “day 2” or “day 21” without first defining day 1 and your actual cycle length is guessing.

Semen testing: follow the receiving laboratory's written abstinence and collection instructions exactly. For off-site collection, confirm the permitted transport time and temperature in advance. And never carry a sample across an international border without explicit legal and laboratory approval.

Review visit: the results deserve to be read as one picture, with the red and green flags explained in context. Ask for a working diagnosis, the confidence behind it, what is still missing, the options and a ranked next step.

Targeted second stage: every repeat or specialist test should trace back to a finding. ESHRE notes that the evidence behind many additional tests for unexplained infertility is limited or very low quality.[8]

Decide which tests from home can safely be reused

Redoing every test wastes time and money. Taking every outside result at face value carries its own risks. Before you travel, ask the Chinese clinician to label each existing result accepted, accepted if still within a stated date window, requires images or methods, or must be repeated.

Run each one through this list:

patient name, date of birth and passport-name match;
specimen or examination date and cycle day;
units and reference interval;
assay platform when serial comparison matters, especially AMH;
complete ultrasound or HSG images, measurements and laterality;
semen collection and processing method;
whether infection tests meet the treatment laboratory's regulatory window; and
whether a translated report preserves numbers, symbols and qualifiers.

Two AMH or semen results that disagree call for a review of method and timing first — “rapid biological decline” is a conclusion to reach only after that check.

Verify the service when assessment may lead to assisted reproduction

Plenty of the diagnostic work can happen in a general gynaecology, urology or andrology clinic. The moment the plan might move on to insemination, IVF, ICSI or PGT, verify the exact institution and which technologies it is approved for. China's National Health Commission publishes information on approved human assisted-reproduction institutions, and provincial authorities handle planning, approval and supervision.[9][10]

Three things to ask: does the team doing the assessment also deliver the treatment, do outside results go into the formal medical record, and is a fresh consultation required before treatment starts. A coordinator can book dates and arrange translations; interpreting ovarian reserve, semen quality or genetic risk is the doctor's job.

Leave with a diagnostic map, even if there is no final diagnosis

The paperwork you leave with should spell out:

duration and route of trying to conceive;
reproductive diagnosis for each partner or participant;
evidence about ovulation, ovarian reserve, uterine cavity, tubes and semen;
which findings are confirmed, borderline, inconsistent or still missing;
age- and diagnosis-related urgency without a guaranteed prognosis;
next option and its clinical objective;
alternatives and the consequence of waiting;
additional tests, each linked to a decision; and
who reviews results and provides follow-up after return home.

When the conclusion reads “unexplained infertility,” confirm that each basic domain was actually evaluated. When it reads diminished ovarian reserve, ask what that predicts — usually the response to stimulation more than natural fertility — and what it changes right now. When semen is abnormal, the male patient deserves a proper clinical assessment, something more than a one-line instruction to proceed to ICSI.

Medical disclaimer: This article is general education. It does not provide an individual fertility diagnosis or order any test. Test selection and timing depend on age, anatomy, symptoms, pregnancy goals and the intended treatment. Get urgent local care for severe pelvic or testicular pain, heavy bleeding, fainting or suspected ectopic pregnancy.

FAQ

Is AMH a test of egg quality or the chance of natural pregnancy?

No. What AMH mainly estimates is how the ovaries are likely to respond to stimulation and how many eggs a cycle might yield. Read it together with age, antral follicle count, history and the treatment goal. It says nothing direct about egg quality, and on its own it predicts natural conception poorly.[2][6]

Does one abnormal semen result mean male infertility is confirmed?

Not on its own. Semen parameters fluctuate, and collection, recent fever, abstinence time, transport and laboratory method all feed into the numbers. The clinician may simply repeat the analysis, and should arrange a male-reproductive evaluation if abnormalities persist or look severe.[3][4]

Do I need hysteroscopy and laparoscopy as part of the first work-up?

Usually they are not routine. Ultrasound plus a tubal-patency test covers the first anatomical questions in most cases. Hysteroscopy or laparoscopy comes in when a cavity, tubal, endometriosis or pelvic problem is suspected, or when an intervention is already planned.[2]
