Begin a focused preconception evaluation now: order serum AMH, day‑3 FSH, a transvaginal antral follicle count, partner semen analysis and an expanded carrier panel, plus rubella/varicella IgG and TSH; these tests show whats most likely to limit conception and guide timeline decisions – if ovarian reserve is reduced, refer to a reproductive endocrinologist within 8–12 weeks because delay could-be costly for options and outcomes.

Start folic acid 400–800 µg daily immediately and prescribe 4 mg only for people with previous neural‑tube defect history; check HbA1c and blood pressure before conception, adjust teratogenic medications, and aim for BMI 18.5–30 to reduce the odds of gestational diabetes and hypertensive disorders. I tell many patients that optimizing these metrics before conception increases the chance a newborn arrives with fewer complications and shortens the need for interventions after the infant has arrived.

Genetic screening strategy: offer carrier screening for recessive conditions and cell‑free DNA for trisomies as first‑line screening; explain detection versus diagnostic differences and that a positive screen should lead to diagnostic testing (CVS/amniocentesis) to confirm. Expect cell‑free DNA sensitivity for common trisomies to be high for older mothers, but discuss residual risk and what a confirmed diagnosis would mean for the family.

Practical planning: schedule a delivery at a facility with appropriate neonatal support, line up lactation counseling and a postpartum follow‑up at 1–2 weeks, and arrange backup childcare if a sibling is at home. In a clinic in Jersey in January I saw a couple who’d planned these steps and found support rapidly; the same preparation let them leave hospital confident when the newborn and sibling were both doing good.

Emotional and decision support: document prior reproductive history, share clear timelines for interventions, and offer a brief consult with a reproductive counselor or fertility nurse so people making the choice to become parents have actionable knowledge. I myself provide written plans that patients can take home – an image of the timeline, next tests and referral dates – so they finally have something concrete rather than vague reassurance.

Preconception Visit: What I Do and Ask During Our First Appointment

Schedule the preconception visit at least 3 months before attempting conception; I review current medications, stop dates for contraception, and order lab testing to detect anemia, TSH abnormalities, A1c, rubella and varicella immunity, hepatitis panel, HIV and syphilis so that given results we can act before conception.

I ask a concise reproductive history: number of prior pregnancies, losses, ectopics and cesareans, dates they were born or ended, and any pregnancy complications that could-be recurrent; I document partners, paternal age as a factor, and whether dads have known genetic conditions or exposures.

I perform or arrange tests: CBC, CMP, A1c, TSH, vitamin D when indicated, urine culture, cervical screening if due, and referral for carrier screening (CF, SMA, hemoglobinopathies) with discussion of results and what those results mean for both members of a couple; I explain prenatal aneuploidy risk by age and offer options for different screening or diagnostic routes.

I take a targeted medication and exposures review: isotretinoin, methotrexate, warfarin and fluorinated medications require stop and washout plans; occupational or travel exposures (for example frequent work travel between Jersey and high-risk areas) and lifestyle factors (smoking, alcohol, weight) are addressed with concrete timelines so youre ready and risk is lowered.

Mental health and social supports are assessed: recent mood shifts, history of postpartum depression, current stressors or crisis, financial and partner support, and plans for childcare; some people expect quick answers, others need slower work to change habits – remind them that regular counseling or therapy can start now and improve outcomes later.

I counsel on folic acid dosing (0.4 mg for average risk, 4 mg if prior neural tube defect or bariatric surgery), optimize vitamin D and iron, and review vaccine updates; example: carla in jersey thought shes immune to rubella but testing hadnt confirmed that, so heres the plan we started to protect a future pregnancy and reduce chances of congenital infection.

I document family histories to detect autosomal or mitochondrial patterns, discuss genetic counseling when indicated, and schedule follow-up visits for results review; expect to return in 2–6 weeks for abnormal findings and again as labs come back so interventions can start sooner rather than later.

For evidence-based guidance and patient materials see the CDC preconception care page: https://www.cdc.gov/preconception/index.html. Regular review of articles and news in obstetrics keeps my knowledge current so patients who started trying earlier or later feel informed about possible different risks and experiences.

Which fertility tests I order and how to interpret AMH and ultrasound results

Firstly, order serum AMH and a transvaginal ultrasound for antral follicle count (AFC) plus baseline FSH and estradiol on cycle day 2–5; these tests together best direct immediate management and timing for treatment.

AMH interpretation (ng/mL and pmol/L): >=3.0 ng/mL (>=21 pmol/L) indicates high ovarian reserve and a huge likelihood of strong ovarian response; 1.0–3.0 ng/mL (7–21 pmol/L) is typical and associated with a normal response; 0.5–1.0 ng/mL (3.5–7 pmol/L) predicts reduced response; <0.3 ng/mL (<2.1 pmol/L) predicts very low response and lower cumulative live birth probability with own oocytes. AMH doesnt measure egg quality or guarantee pregnancy; age and maternal health determine oocyte competence. Use AMH to select stimulation dose, counsel about risks of hyper-response, and decide whether to consider donor oocytes or mild protocols.

Ultrasound interpretation: count visible antral follicles 2–10 mm in both ovaries (AFC). AFC >20 suggests polycystic pattern and increased OHSS risk; AFC 10–20 = good reserve; AFC 4–9 = low reserve; AFC <4 >3 cm should be assessed before stimulation. Image quality matters–use a high-frequency transvaginal probe and perform the scan during early follicular phase for reproducible counts. If ovaries dont respond to expected stimulation despite normal AMH and AFC, investigate thyroid, prolactin, and pelvic adhesions.

Test Timing Key thresholds Practical interpretation Recommended action
AMH (serum) Any day; measured today or pre-cycle >=3.0 / 1.0–3.0 / 0.5–1.0 / <0.3 ng/mL Estimates quantitative reserve; predicts oocyte yield, not quality Adjust stimulation dose; discuss IVF vs expectant management; consider egg banking if successful fertility is urgent
Transvaginal ultrasound (AFC) Cycle day 2–5 for standardization >20 / 10–20 / 4–9 / <4 follicles Visual correlate to AMH; flags PCOS pattern, low reserve, structural issues Plan stimulation protocol; treat polyps/fibroids before embryo transfer; repeat if image poor
FSH + estradiol Cycle day 2–5 FSH <10 mIU/mL typical; higher suggests diminished reserve Useful when AMH/AFC discordant Confirm diminished reserve; consider earlier intervention
TSH, prolactin, basic infection screen Any time during workup Normal lab ranges Exclude reversible endocrine or infectious causes of subfertility Treat thyroid or prolactin abnormality; clear infection before ART

In clinic I recommend repeat AMH only if there are major medical changes or assay differences; AMH is fairly stable but different labs use different assays so be prepared to compare units or request the same lab. Colleagues Tweedie, Carla and Paul and I truly find that combining AMH and AFC gives everything needed to counsel about timing, protocols and realistic chances. If AMH and AFC are low, discuss the advantages of early IVF, egg donation, or fertility preservation; some individuals still become pregnant naturally, but response to stimulation may be poor.

Practical notes: check that their ultrasound image counts follicles 2–10 mm only, confirm regular cycles before assuming young ovarian age, and prepared to escalate workup if tests are discordant. Expect a huge range of experiences: some with low reserve respond well and achieve successful outcomes; others possibly need donor options. Mention maternal and motherhood risks during counseling, and give clear numeric odds rather than vague news–this helps people plan and respond without false optimism.

When I recommend referral to a fertility specialist or IVF consultation

When I recommend referral to a fertility specialist or IVF consultation

Refer to a fertility specialist immediately if any of these objective criteria are met: woman aged ≥37 who has tried to conceive for >6 months; AMH <1.0 ng/mL or a falling AMH over 6–12 months; day‑3 FSH >10 IU/L; antral follicle count (AFC) <7; bilateral tubal occlusion or documented hydrosalpinx; severe endometriosis (stage III–IV) with infertility; recurrent pregnancy loss ≥2 with incomplete workup; severe male factor (total motile sperm count <5 million or azoospermia); or need for fertility preservation prior to gonadotoxic therapy.

IVF prognosis data to discuss at consultation: live‑birth per transfer averages ~40–50% for <35, ~30% for 35–37, ~15–20% for 38–40 and ~5–10% for >40; embryonic aneuploidy increases from roughly 40% at 35 to ~80–90% by early 40s. Include explicit counseling about risks: ovarian hyperstimulation syndrome, procedure‑related complications, and emotional and financial burden. Discuss fresh versus frozen strategies, PGT‑A impact on transfer decisions, and how those choices affect time to pregnancy.

Recommended route depends on the diagnosis: IVF with ICSI for severe male factor or obstructed tubes; donor oocyte when AMH is extremely low (for example <0.2 ng/mL) or age and reserve predict poor response; surgical correction for removable uterine pathology or tubal disease where appropriate; fertility preservation if chemotherapy is planned. A complete evaluation – including semen analysis, HSG or saline sonohysterography, AMH, AFC and genetic carrier screening – does expedite clear decision‑making. Typical clinic costs per fresh cycle range widely ($12,000–25,000 excluding meds; meds ~$3,000–8,000) and clinics will estimate number of cycles likely needed to achieve live birth based on age and reserve.

Clinical examples clarify what I would recommend: kendra headley, age 38, had spent 18 months trying despite regular cycles and a younger partner with normal semen analysis; after three failed IUI cycles and an AMH of 0.6 ng/mL she was referred, gone through one IVF retrieval with PGT‑A and felt glad she had decided to consult early. Many individuals report the emotional experience is easier when there is a clear plan; they want to know what success probability is, what the risks are, and whether donor egg or embryo banking makes a better long‑term position. If you are not ready for donor options, referral lets you understand timelines, the route that best matches your goals, and what being in a proactive treatment pathway does to chances of conceiving.

Medication, vaccine, and supplement changes I advise before conception

Stop isotretinoin immediately and arrange pregnancy testing and contraception; isotretinoin requires a minimum 28‑day washout after the last dose before attempting conception. Discontinue methotrexate and wait at least 3 months (6 months if high cumulative dose or male carrier) because of teratogenicity and delayed gamete effects.

Replace warfarin with low‑molecular‑weight heparin before trying to conceive and plan anticoagulation with the ob-gyn team; never stay on ACE inhibitors or ARBs–switch to labetalol, nifedipine, or methyldopa for blood pressure control prior to conception. Stop statins and finasteride; consult neurology for alternatives to valproate and carbamazepine if seizure control allows, as those carry higher neural tube and developmental risks.

Live vaccines (MMR, varicella) must be given at least 28 days before conception; check rubella and varicella IgG now and vaccinate if nonimmune. Inactivated influenza and COVID vaccines may be given preconception; complete hepatitis B series if seronegative. Tdap is ideally arranged with the pregnancy plan (will be recommended during gestation), but ensure tetanus/diphtheria immunity is up to date beforehand.

Begin folic acid 400–800 µg daily immediately; increase to 4 mg daily if prior neural tube defect, on antiepileptic therapy, or other high‑risk conditions. Add vitamin D 1,000–2,000 IU daily if 25‑OH D <30 ngml. consider dha 200–300 mg daily for fetal neurodevelopment support. avoid supplements with preformed vitamin a>10,000 IU (retinol) and herbal stuff with unknown reproductive safety; read labels and bring products to the clinic for review.

Order baseline tests now: rubella IgG, varicella IgG, TSH (aim for trimester‑specific targets with thyroid replacement adjusted beforehand), HbA1c if diabetes or elevated risk (target individualized; many strive for <6.5% preconception), CBC, CMP, and medication level monitoring when relevant. A medication reconciliation with the ob-gyn or primary care clinician will flag drug‑drug interactions and allow a clear path for switching or tapering.

Psychotropic meds: do not stop SSRIs abruptly. Plan tapering or substitution with a psychiatry or ob-gyn co-management plan because relapse risk is high; many mothers who stopped without a plan gave a history of relapse and had to reintroduce meds. Discuss breast‑feeding plans early so changes now will respond to later parenting goals and bonding relationship choices.

Document vaccine and lab results in the record so results can be read back into prenatal care; in most cases a focused preconception visit reduces teratogenic risk and makes conception more likely to be smoother. For different chronic conditions, individual risk stratification will identify the best timing and specific tests to run throughout preconception planning.

Keep a concise checklist: meds to stop and dates, vaccines given and wait periods, supplements started with doses, and baseline tests ordered. That list is a handy gift to hand to any clinician you see so care remains coordinated and responsive as plans move into the phase of becoming a parent and a new child is born.

How I assess chronic conditions (hypertension, diabetes, thyroid) and adjust care

Obtain baseline labs and home data before conception: HbA1c, fasting glucose, TSH with free T4, CMP (including creatinine, electrolytes, LFTs), urine albumin‑creatinine ratio, and 7–14 days of twice‑daily home blood pressure readings; aim preconception HbA1c <6.5% if achievable without hypoglycemia and TSH 0.5–2.5 mIU/L.

Zaznamenávejte obsah diskuzí a poskytněte jednopagedový plán, který si jednotlivec může uložit do telefonu; zjistíte, že konkrétní cíle, jasná data pro změnu léků a plánované časy sledování snižují riziko a činí péči o plodnost v středním věku a těhotenskou péči jako zvládnutelný, svěží plán společně, nikoli jako dohodu bez časového omezení s nejistotou.

Praktický časový harmonogram, který poskytuji pacientům pro zkoušení, sledování a další kroky

Okamžitě zahajte časovaný pohlavní styk s monitorováním ovulace; pokud nedojde k početí po čtyřech cyklech (≈16 týdnů), zahajte diagnostické testování namísto pokračování v neslepech pokusech.

Prvních 0–4 týdnů: používejte ovulační testovací sady a sledování hlenu z děložního čípku jako nástroje; užívejte kyselinu listovou 400–800 µg denně, přestaňte kouřit a optimalizujte BMI. Pokud jsou cykly nepravidelné, nechte si udělat základní sérový progesteron v luteální fázi, abyste potvrdili ovulaci.

Čtyři až šestnáct týdnů (čtyři cykly): pokud není těhotenství, objednejte laboratorní testy dny 2–4: AMH, FSH, estradiol, TSH, prolaktin; transvaginální sčítání antrálních folikulů ultrazvukem; spermiální analýza partnera; nabídněte genetické testování nositelů. Tyto testy umožňují lidem pochopit zásobu vaječníků a genetická rizika, aby mohli brzy volit možnosti.

Pokud abnormální výsledky nebo věk nad 40 let: odkaz na reprodukční endokrinologii dříve – mnoho by pokračovalo v asistované reprodukci po třech cyklech, pokud je AMH nízký nebo FSH zvýšený. Typické další kroky: indukce ovulace s IUI u vybraných případů nebo přechod k IVF s diskuzí o preimplantační genetické diagnostice (PGT-A), pokud jsou k dispozici embrya a existují genetické obavy.

Sledování během léčby: základní ultrazvuk, sérový estradiol a sledování folikulů každých 2–3 dny během stimulace; upravte medikaci podle odezvy, abyste předešli OHSS. Vždy si prostudujte specifická rizika a statistiky úspěšnosti zvoleného protokolu; realistické očekávání na cyklus se s postupujícím věkem výrazně snižuje, takže eskalujte dříve než později, pokud je rezerva špatná.

Pokud dojde k početí: nabídka ultrazvuku v časném stádiu těhotenství ve 6–7 týdnech, neinvazivní prenatální testování kolem 10. týdne pro screening aneuploidií a odeslání k specialistovi na matku a plod, pokud jsou přítomny genetické nebo porodnické rizikové faktory. Pokud není těhotenství dosaženo po diagnostickém vyšetření, prodiskutujte darování gamet, darování embryí nebo adopci jako platné, plánované možnosti.

Přehled časování: zkuste časované přirozené cykly až po dobu čtyř cyklů, pokud je rezerva dostatečná; spusťte základní panel při prvním náznaku neúspěchu; eskalujte na asistované metody během tří až čtyř cyklů pro sníženou rezervu nebo pokud je pravděpodobné, že věkem související pokles povede k neúspěšnému dlouhému čekání.

Lidé často čtou zprávy a mluví o dokonalých příbězích; případná ukázka – karg a oconnor jsou zástupci dvou různých trajektorií: jedna babička, která trvala déle než obvykle, strávila extra měsíce s IUI než s IVF, a byla ráda, že si pročetla dostupná data a otevřeně mluvila o rizicích; druhá přestala čekat a zvolila dárkyni vajíček dříve a dosáhla úspěšného výsledku. Umožnění jednotlivcům vidět možnosti jim pomáhá učinit rozhodnutí, které se jim zdá správné, akceptovat, že výsledky nejsou dokonalé, ale mohou být přesto krásné navzdory překvapením.
