What Checks Should You Do Before Pregnancy at an Advanced Maternal Age? A Complete 2026 Guide
Bottom Line First: You Need Five Categories of Tests, Done 3–6 Months Before You Start Trying.
Advanced maternal age (35+) does not mean you cannot get pregnant. But it does mean your body needs a full mechanical inspection before you hand it the most demanding job it will ever do. The goal is not to scare you. The goal is to find every hidden problembeforeyou conceive, so you can fix it while there is still time.深圳人工流產醫院
Here is every single test you need, why you need it, and when to do it.
Category 1: Ovarian Reserve Evaluation — How Many Eggs Do You Actually Have Left?
This is the single most important category for women over 35. Your chronological age tells one story. Your ovarian age tells the real one.
| Test | When to Do It | What It Tells You | Why It Matters |
|---|---|---|---|
| AMH (Anti-Müllerian Hormone) | Any day of your cycle | Direct measure of remaining egg count | AMH below 1.0 ng/mL at age 35+ means significantly reduced reserve. Below 0.5 means very low. This number does NOT predict egg quality, only quantity |
| Day 2–4 FSH (Follicle-Stimulating Hormone) | Day 2–4 of your period | How hard your brain is screaming at your ovaries to work | FSH above 10–12 IU/L suggests your ovaries are struggling to respond. Above 20 IU/L is a red flag |
| Estradiol (E2) on Day 2–4 | Same blood draw as FSH | Baseline estrogen level | If E2 is abnormally high on Day 2–4, it can falsely suppress FSH, giving a fake "normal" reading. Both must be read together |
| AFC (Antral Follicle Count via Ultrasound) | Day 2–5 of your period | Actually counts the small follicles visible on ultrasound深圳人工流產邊間好 | Combined with AMH, this gives the most accurate picture. AMH low + AFC normal = possible granulosa cell dysfunction. AMH high + AFC low = possible measurement error |
| LH (Luteinizing Hormone) | Day 2–4 of your period | Ovulation trigger hormone | Elevated LH can indicate PCOS or early ovarian aging |
Key takeaway: AMH + AFC + FSH together form the "ovarian reserve triad." Any one of them abnormal warrants a deeper conversation with a reproductive specialist. Do not rely on just one number.
Category 2: Endocrine & Metabolic Screening — Is Your Hormonal Engine Running Properly?
Your hormones control everything: ovulation, implantation, early pregnancy maintenance. At 35+, these systems start to drift.
| Test | What It Screens For | Why It Is Critical for 35+ |
|---|---|---|
| Thyroid Function (TSH + Free T4 + TPOAb) | Hypothyroidism, subclinical hypothyroidism, autoimmune thyroid disease | TSH above 2.5 mIU/L is now considered suboptimal for pregnancy. Untreated hypothyroidism causes miscarriage, poor fetal brain development, and preterm birth. TPOAb positive means autoimmune thyroid disease — you need closer monitoring throughout pregnancy |
| Fasting Glucose + HbA1c | Pre-diabetes, insulin resistance | Age 35+ is when insulin resistance starts creeping in silently. Undiagnosed pre-diabetes at conception increases gestational diabetes risk by 3–4x |
| OGTT (Oral Glucose Tolerance Test) + Insulin Release Test | Hidden glucose metabolism problems深圳人工流產费用 | If you have PCOS, obesity, or family history of diabetes, this is mandatory. It catches problems that fasting glucose alone will miss |
| Prolactin | Hyperprolactinemia | High prolactin suppresses ovulation. If your periods are irregular, this test is non-negotiable |
| Vitamin D | Deficiency | Over 60% of women of reproductive age in northern latitudes are deficient. Low Vitamin D is linked to PCOS, endometriosis, and lower IVF success rates |
Key takeaway: Thyroid and glucose metabolism are the two most commonly missed problems in advanced-age备孕. Get them checked even if you feel perfectly fine.
Category 3: Genetic Screening — What Are the Risks Your Baby Could Inherit?
This is the category most people skip. It is also the category that matters most after 35.
| Test | Who Needs It | What It Finds |
|---|---|---|
| Chromosome Karyotyping (both partners) | Everyone 35+ | Detects balanced translocations, inversions, and other structural abnormalities. If one parent carries a balanced translocation, the risk of miscarriage or chromosomally abnormal pregnancy jumps dramatically |
| Expanded Carrier Screening | All couples, especially Asian descent | Screens for 200+ recessive genetic diseases including spinal muscular atrophy (SMA), cystic fibrosis, and thalassemia. Asian populations have a carrier rate of up to 1 in 20 for thalassemia |
| Thalassemia Gene Test | Mandatory for Chinese/Southeast Asian/South Asian couples | If both partners are carriers, there is a 25% chance per pregnancy of a child with major thalassemia |
| Folate Metabolism Gene (MTHFR) | Optional but recommended深圳人工流产 | Tells you whether you metabolize folic acid normally. If you have the C677T mutation, you may need activated folate (5-MTHF) instead of regular folic acid |
| PGT-A Consultation | If you have recurrent miscarriage, repeated IVF failure, or known genetic risk | Preimplantation Genetic Testing for Aneuploidy screens embryos for chromosomal abnormalities before transfer. This is not a "test" you take — it is a procedure discussed with your IVF doctor |
Key takeaway: After 35, the risk of chromosomal abnormalities in eggs rises sharply. At age 35, the risk of Down syndrome is about 1 in 350. At age 40, it jumps to 1 in 100. At age 45, it is 1 in 30. Genetic screening does not eliminate risk, but it lets you make informed decisions.
Category 4: Reproductive System Check — Is the "Factory" Structurally Sound?
| Test | What It Checks | Why It Matters at 35+ |
|---|---|---|
| Pelvic Ultrasound (Transvaginal) | Uterus shape, endometrial thickness, fibroids, polyps, ovarian cysts, AFC | Age 35+ brings higher rates of fibroids, polyps, and endometrial changes. A polyp as small as 5mm can reduce implantation rates by 50% |
| HSG (Hysterosalpingography) or HyCoSy | Fallopian tube patency | Blocked tubes are a silent killer. You can have perfect eggs and perfect sperm, but if the tubes are blocked, fertilization never happens. HSG also has a mild therapeutic effect — it can actually improve fertility in some women |
| TCT (Cervical Cytology) + HPV Test | Cervical precancerous changes | HPV persistence increases with age. Catching it before pregnancy prevents complications during pregnancy when treatment options are limited |
| Vaginal Discharge + STI Panel (Chlamydia, Gonorrhea, Mycoplasma, Ureaplasma) | Active infections深圳人工流產多少錢 | Untreated infections cause pelvic inflammatory disease, tubal scarring, and ectopic pregnancy. Many infections are completely asymptomatic |
| Hysteroscopy (if ultrasound shows abnormalities) | Direct visualization of the uterine cavity | Gold standard for diagnosing polyps, adhesions (Asherman's syndrome), and submucosal fibroids. If you have had any uterine surgery (D&C, myomectomy), this is strongly recommended |
Key takeaway: A normal period does NOT guarantee a normal uterus. Many structural problems are completely silent until you try to conceive.
Category 5: General Health & Infection Screening — Can Your Body Handle Pregnancy?
Pregnancy is a metabolic marathon. Your heart, liver, kidneys, and immune system all work at 2–3x capacity. At 35+, you need to make sure none of these systems have hidden weakness.
| Test | What It Finds | Threshold for Concern |
|---|---|---|
| Complete Blood Count (CBC) | Anemia, infection, platelet disorders | Hemoglobin below 11 g/dL = iron deficiency anemia. Must be corrected before conception. Low platelets = bleeding risk during delivery |
| Liver Function (ALT, AST, Bilirubin) | Liver health | Elevated liver enzymes may indicate fatty liver, which is extremely common in women 35+ and affects hormone metabolism |
| Kidney Function (Creatinine, BUN, Uric Acid) | Kidney health | Pregnancy increases kidney workload by 50%. Hidden kidney damage can become a serious pregnancy complication |
| Lipid Panel | Cholesterol,深圳終止懷孕 triglycerides | Dyslipidemia increases preeclampsia and cardiovascular risk during pregnancy |
| Blood Pressure (multiple readings) | Hypertension | Chronic hypertension must be controlled before conception. Some BP medications are teratogenic and need to be switched |
| ECG + Cardiac Ultrasound (if indicated) | Heart function | Pregnancy increases blood volume by 40–50%. Undiagnosed heart conditions can become life-threatening |
| TORCH Panel (Toxoplasma, Rubella, CMV, HSV) | Infections that cause birth defects | Rubella immunity must be confirmed BEFORE pregnancy. If you are not immune, get vaccinated and wait 3 months before trying. CMV and toxoplasma can cause fetal brain damage |
| Infectious Disease Panel (Hepatitis B, Hepatitis C, Syphilis, HIV) | Transmissible infections | Hepatitis B carriers need viral load testing and possibly antiviral therapy. Syphilis must be fully treated before conception. HIV requires specialist management for safe conception |
| Bone Density (DEXA) | Osteoporosis risk | Age-related calcium loss accelerates after 35. Pregnancy and breastfeeding further deplete calcium stores |
| Dental Checkup | Gum disease, cavities | Periodontitis is linked to preterm birth and low birth weight. Get any infections treated before conception |
Category 6: Male Partner Testing — It Takes Two深圳怡康醫院好唔好
This is the most neglected category. Roughly 40–50% of infertility cases involve male factors. The man's age matters too — paternal age over 40 increases risks of autism, schizophrenia, and certain dominant genetic conditions.
| Test | What It Checks | Key Threshold |
|---|---|---|
| Semen Analysis (abstain 3–7 days) | Sperm count, motility, morphology | WHO 2021 criteria: count ≥16 million/mL, total motility ≥42%, normal morphology ≥4%. Below these = subfertility |
| Sperm DNA Fragmentation Index (DFI) | DNA damage in sperm | DFI above 30% is associated with higher miscarriage rates and lower IVF success, even when semen analysis looks normal |
| Y Chromosome Microdeletion | Genetic cause of severe oligospermia/azoospermia | If sperm count is very low, this test is mandatory |
| Male Infectious Disease Screening | Hepatitis B, Syphilis, HIV | Same rationale as female screening |
| Male Hormone Panel (if indicated) | Testosterone, FSH, LH | Low testosterone + high FSH = primary testicular failure |
The Timeline: When to Do What終止懷孕收費
| Timeline Before Trying | Action |
|---|---|
| 6 months before | Complete all blood work, ultrasound, genetic screening, dental checkup |
| 3 months before | Start folic acid (0.4–0.8 mg/day, or 5-MTHF if MTHFR mutation positive). Switch to prenatal vitamin with iron, iodine, and Vitamin D |
| 1 month before | Confirm all results are normal. Begin cycle tracking (basal body temperature + ovulation tests) |
| Day 1 of trying | You are ready |
What Happens If Something Comes Back Abnormal?
| Problem Found | Typical Action |
|---|---|
| AMH very low (<0.5) | Do not wait. See a reproductive specialist immediately. IVF with micro-stimulation protocol may be your best option |
| TSH elevated | Start levothyroxine. Target TSH below 2.5 before conception. Recheck every 4–6 weeks |
| Glucose intolerance | Diet modification + metformin if needed. Lose 5–10% body weight. Recheck in 3 months |
| Blocked fallopian tubes | HSG may have partially cleared them. If still blocked, IVF is the fastest path |
| Uterine polyp/fibroid | Hysteroscopic removal. Wait 1–2 menstrual cycles before trying大陸人工流產 |
| Chromosome translocation found | Genetic counseling. PGT-A with IVF is strongly recommended |
| Male factor (low motility/high DFI) | Antioxidant supplementation (CoQ10, Vitamin E, Zinc, Selenium) for 3 months. Recheck semen. Consider IUI or IVF-ICSI if no improvement |
The Non-Negotiable Lifestyle Checklist深圳人工流產
| Action | Minimum Requirement |
|---|---|
| Sleep | In bed by 11 PM. 7–8 hours. Disrupted sleep raises cortisol, which suppresses ovulation |
| Exercise | 150 minutes/week moderate intensity (brisk walking, swimming). Avoid extreme exercise — it can shut down ovulation |
| Caffeine | Under 200 mg/day (about one 12oz coffee) |
| Alcohol | Zero during the trying phase |
| Smoking | Zero. Smoking ages ovaries by 2–4 years |
| Weight | BMI 18.5–24.9. Both underweight and overweight reduce fertility |
| Folic acid | 0.4–0.8 mg/day, started at least 3 months before conception |
| Stress management | Chronic stress raises cortisol, which directly suppresses GnRH pulsatility and ovulation. Meditation, counseling, or even just regular walks help |
One Final Truth深圳人工流產手術
Advanced maternal age is not a disease. It is a risk factor. And risk factors are manageable — if you know what they are.
The difference between a 38-year-old who panics for two years and a 38-year-old who walks into a reproductive specialist with a complete set of test results is enormous. One wastes time. The other gets pregnant.
Start the tests now. Not next month. Not "when I feel ready." Now.
