Controlled Ovarian Stimulation (COS) with gonadotropins to produce multiple follicular development and high-quality oocytes is the cornerstone of Assisted Reproductive technology. Today, Recombinant human follicle-stimulating hormone (r-hFSH) as well as Biosimilars are widely used for COS. A long-acting r-hFSH and a combination of r-hFSH and recombinant human luteinizing hormone have recently become available. Formulations of purified urinary FSH with or without luteinizing hormone activity (provided by human chorionic gonadotropin) are also available. COS protocols can now be individualized to optimize efficacy and safety – defined as euploid singleton pregnancies with a low incidence of ovarian hyperstimulation syndrome. This is facilitated by an estimation of ovarian response using the antral follicle count and/or serum anti-Müllerian hormone levels; anti-Müllerian hormone is viewed as the most reliable single marker. However, an efficient management strategy for poor responders to COS is still required. Developments in Biomarkers and other techniques for accurate identification of viable oocytes and embryos and optimal uterine receptivity are expected.
Inter-individual variation in ovarian response represents a significant clinical and economical challenge. Undoubtedly, there is a need to reliably predict ovarian response to stimulation, to tailor stimulation protocols optimizing the probability of pregnancy and keep at the same time the risks of complications and costs at a minimum. Consequently the academic world is still researching individualised Controlled Ovarian Stimulation Protocols(iCOS) or Personalised Controlled Ovarian Stimulation Protocols(peCOS).
Special emphasis needs to be given on how to avoid excessive response and predict the occurrence of Ovarian Hyperstimulation Syndrome (OHSS), as well as on maximizing tolerability of treatment from a patient’s perspective.
