Endometriosis in Valongo, Portugal: diagnosis, treatment and reference centres

Affects roughly 10% of women of reproductive age. Among infertility patients, prevalence rises to 25–50%.

Portugal does not publish population-level epidemiological registries specific to Endometriosis, but international data applies. Regionally, demand for reproductive medicine consultations in Norte 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 Endometriosis 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.

Clinical assessment + specialist transvaginal ultrasound (endometriomas, deep nodules). Pelvic MRI for deep infiltrating endometriosis. Diagnostic laparoscopy only when it changes management. ESHRE 2022 advises against routine laparoscopy in asymptomatic women.

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 Valongo, the couple is typically referred to Porto or another city with a licensed PMA centre, keeping baseline tests and ultrasound local.

Official sources: this protocol follows ESHRE Guideline: Endometriosis (2022). The DGS and CNPMA recognise these international guidelines as the basis for clinical care in Portugal.

Minimal/mild endometriosis with infertility: laparoscopic surgery may increase spontaneous pregnancy (NNT~12). Moderate/severe or age >35: IVF often first line. Endometrioma ≥3cm: weigh excision vs direct IVF (ovarian reserve trade-off). Adenomyosis may reduce implantation — discuss pre-transfer GnRHa.

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.

Valongo 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 Porto. This logistics model is common in Portugal and aligned with ESHRE recommendations for decentralised access.

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

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 Endometriosis 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.
