Current approaches to diagnosing and managing female poor responders to ovarian stimulation with gonadotropins in assisted reproductive technology programs
Female poor responders to ovarian stimulation (OS) make up a large cohort among all infertile women seeking assisted reproductive technology (ART) programs (9–24%). The Bologna criteria do not fully reflect the diverse group of female poor responders to OS. The novel POSEIDON classification stratifies a large heterogeneous cohort of female poor responders into 4 groups according to the age of patients, the levels of antral follicle and anti-Müllerian hormone, and the prognosis of pregnancy. The paper gives possible mechanisms for the pathogenesis of a poor response to OS. Particular attention is paid to patients with normal ovarian reserve and an unpredictable poor response to OS (1, 2 POSEIDON), which is associated with the lower ovarian sensitivity to gonadotropin stimulation due to the presence of polymorphisms in the genes of gonadotropins and their receptors. The authors discuss whether it is expedient to use new clinical and laboratory poor response predictors (FORT, FOI, and OSI). The use of an ART calculator is shown to be appropriate for predicting the number of oocytes required to obtain at least one euploid blastocyst. The paper presents different approaches to optimizing treatment in female poor responders, depending on whether they belong to a particular POSEIDON group. It considers adjuvant therapy methods aimed at obtaining a larger number of oocytes and increasing the effectiveness of ART programs.Perminova S.G., Belova I.S., Mityurina E.V., Savostina G.V.
Conclusion: Using the POSEIDON criteria in clinical practice, clarifying the prognostic value of the new diagnostic criteria (FORT, FOI, and OSI) for a poor ovarian response to gonadotropin stimulation, and assessing the feasibility of testing for polymorphisms in the genes of gonadotropins and their receptors in unpredictable poor responders to OS can be a help in better assessing a large heterogeneous group of poor responders to OS and elaborating personalized approaches to OS in the IVF program, which requires further investigations.
