Recurrent pregnancy loss in Constância, Portugal: diagnosis, treatment and reference centres

About 1–2% of couples experience ≥3 losses; ~5% experience 2 consecutive losses. Incidence rises significantly after the female partner reaches age 35.

Portugal does not publish population-level epidemiological registries specific to Recurrent pregnancy loss, but international data applies. Regionally, demand for reproductive medicine consultations in Centro has risen steadily since 2010 per CNPMA annual reports. This reflects both delayed motherhood (mean age at first child in Portugal: 31.2 years, INE 2024) and greater reproductive health literacy.

Early recognition of Recurrent pregnancy loss preserves treatment options. Women with risk factors — family history, irregular cycles, chronic pelvic pain, or unsuccessful conception attempts ≥6 months at age >35 — should seek specialist evaluation without waiting the conventional 12 months.

Work-up after 2 consecutive losses (ESHRE 2023). Panel: parental karyotype, antiphospholipid antibodies (LAC, aCL, anti-β2GP1), TSH, HbA1c, 3D ultrasound or saline infusion sonography for uterine cavity. PGT-A may be considered when a recurrent chromosomal cause is identified.

In Portuguese practice, the pathway is: (1) GP consultation for baseline labs and ultrasound; (2) referral to gynaecology / reproductive medicine via SNS or direct private consultation; (3) full couple work-up even when the symptom seems isolated to one partner. In Constância, the couple is typically referred to Santarém or another city with a licensed PMA centre, keeping baseline tests and ultrasound local.

Official sources: this protocol follows ESHRE Guideline: Recurrent Pregnancy Loss (2023 update). The DGS and CNPMA recognise these international guidelines as the basis for clinical care in Portugal.

Antiphospholipid syndrome: aspirin + LMWH. Thyroid dysfunction: levothyroxine to TSH <2.5. Correctable uterine anomaly: hysteroscopy. Unexplained (~50%): emotional support and close follow-up in next pregnancy yield ~75% success. PGT-A in IVF is debated — discuss case-by-case.

Treatment choice should always weigh: female age, infertility duration, ovarian reserve (AMH), male factor, comorbidities, and patient preferences. Each option has different efficacy, risk, and cost profiles. Related treatments commonly discussed in consultation: fiv, icsi.

Plans often evolve from less to more invasive options based on response. We recommend requesting a written plan that defines the maximum number of cycles before re-evaluation, objective criteria for strategy change, and the expected impact of each decision on cumulative pregnancy probability.

Constância does not currently host a CNPMA-licensed PMA centre in the municipality. The typical pathway involves: initial consultations and baseline tests (hormones, ultrasound, semen analysis) locally, with referral to the nearest authorised unit — usually Santarém. This logistics model is common in Portugal and aligned with ESHRE recommendations for decentralised access.

For SNS, referral follows the Centro ARS. Privately, clinics in Santarém may offer remote monitoring or partner with local professionals. See the clinic directory in Santarém.

Access to infertility treatment in Portugal is regulated by Law 32/2006 (amended 2016 and 2021). Couple rights: technique-specific written informed consent, access to the medical record, second opinion, and complaint with the Health Regulator (ERS). Embryo cryopreservation is capped at 3 renewable years; gamete donation is anonymous by default (offspring may access non-identifying data at age 18).

The psychological impact of Recurrent pregnancy loss is frequently underestimated. The Portuguese Society of Reproductive Medicine recommends structured psychological support, particularly after pregnancy loss, cycle failure, or diagnosis that changes the parental project. Many PMA units include in-house psychology; alternatively the Portuguese Order of Psychologists maintains a directory of fertility-specialised professionals.
