Low Prognosis by the POSEIDON Criteria in Women Undergoing Assisted Reproductive Technology: A Multicenter and Multinational Prevalence Study of Over 13,000 Patients

Abstract

ObjectiveTo estimate the prevalence of low-prognosis patients according to the POSEIDON criteria using real-world data.DesignMulticenter population-based cohort study.SettingsFertility clinics in Brazil, Turkey, and Vietnam.PatientsInfertile women undergoing assisted reproductive technology using standard ovarian stimulation with exogenous gonadotropins.InterventionsNone.Main outcome measuresPer-period prevalence rates of POSEIDON patients (overall, stratified by POSEIDON groups and by study center) and the effect of covariates on the probability that a patient be classified as “POSEIDON”.ResultsA total of 13,146 patients were included. POSEIDON patients represented 43.0% (95% confidence interval [CI] 42.0–43.7) of the studied population, and the prevalence rates varied across study centers (range: 38.6–55.7%). The overall prevalence rates by POSEIDON groups were 44.2% (group 1; 95% CI 42.6–45.9), 36.1% (group 2; 95% CI 34.6–37.7), 5.2% (group 3; 95% CI 4.5–6.0), and 14.4% (group 4; 95% CI: 13.3–15.6). In general, POSEIDON patients were older, had a higher body mass index (BMI), lower ovarian reserve markers, and a higher frequency of female factor as the primary treatment indication than non-POSEIDON patients. The former required larger doses of gonadotropin for ovarian stimulation, despite achieving a 2.5 times lower number of retrieved oocytes than non-POSEIDON patients. Logistic regression analyses revealed that female age, BMI, ovarian reserve, and a female infertility factor were relevant predictors of the POSEIDON condition.ConclusionsThe estimated prevalence of POSEIDON patients in the general population undergoing ART is significant. These patients differ in clinical characteristics compared with non-POSEIDON patients. The POSEIDON condition is associated with female age, ovarian reserve, BMI, and female infertility. Efforts in terms of diagnosis, counseling, and treatment are needed to reduce the prevalence of low-prognosis patients.

Do we overlook predictive factors in Poseidon 1 patients? A retrospective analysis co-evaluating antral follicle counts & diameters

“…On the other hand, women aged 35 years and older with similar outcomes are categorized as POSEIDON Group 2a and 2b. Recent evidence confirmed that Poseidon groups 1 and 2 have significantly lower live birth rate (LBR) when compared with women having more than 9 oocytes retrieved, confirming the capability of Poseidon classification to identifying different low prognosis segments [ 7 ]. The exact etiology of uIOR or POSEIDON-1 remains unclear.…”

The impact of Resveratrol on the outcome of the in vitro fertilization: a pilot randomized controlled trial

“…Women characterized by a reduced ovarian sensitivity (or "hypo-response") are characterized by reduced the number of eggs retrieved despite the normal ovarian reserve. Evidence indicates that hypo-response is typically observed in women with reduced IVF prognosis (5)(6)(7)(8)(9). So far, several ovarian sensitivity indicators have been proposed (10,11).…”
