This study aimed to develop and validate a predictive model for failure to collect oocytes in the Patient-Oriented Strategies Encompassing Individualized Oocyte Number (POSEIDON) Groups 3 and 4 during their first in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) cycle. A retrospective analysis was conducted on patients in POSEIDON Groups 3 and 4 who underwent their first IVF/ICSI cycle at our center from January 2016 to December 2023. A total of 2,373 patients were randomly assigned to the training or validation cohort at a ratio of 6:4.

Background: The gonadotropin-releasing hormone antagonist (GnRH-ant) protocol is associated with few oocytes retrieved, few mature oocytes and poor endometrial receptivity. Omission of GnRH-ants on trigger day seems unlikely to induce preovulation and may improve outcomes in the GnRH-ant protocol. This study aimed to systematically evaluate the effects of GnRH-ant cessation on trigger day on in vitro fertilisation outcomes following the GnRH-ant protocol.

Background: In a global effort to assess expert perspectives on the use of recombinant gonadotropins, recombinant human luteinizing hormone (r-hLH) and recombinant human follicle-stimulating hormone (r-hFSH), a consensus meeting was held in Dubai. The key aim was to address three critical questions: What are the factors that influence follicle response to gonadotropins? Which categories of patients are most likely to benefit from LH supplementation? And what are the optimal management strategies for these patients?
Methods: A panel of thirty-six experts reviewed and refined the initial statements and references proposed by the Scientific Coordinator. Consensus was defined as agreement or disagreement by more than two-thirds (66%) of the panel members for each statement.

The research investigated the capacity of myo-inositol (MI) in order that it improves biochemical markers in serum and follicular fluid and, ultimately, intracytoplasmic sperm injection (ICSI) outcomes of women with PCOS. Sixty infertile patients with PCOS, who were undergoing ovulation induction for ICSI, were randomly divided to two groups. The MI group received 2000 mg myo-inositol + 1 mg folic acid twice a day for 6 weeks with starting the ICSI cycle.

Background: A normal luteal function is an essential factor for maintaining pregnancy; luteal phase deficiency decreases embryo implantation and pregnancy rate and increases the early miscarriage rate. In stimulated in vitro fertilization-embryo transfer (IVF-ET) patients, luteal phase support (LPS) is achieved by the exogenous supplementation with progesterone to increase endometrial receptivity and pregnancy. While several protocols exist, no commonly accepted protocol has been established for optimal luteal support after IVF-ET to date, the purpose of this study was to investigate the effect of two different luteal phase support protocols in patients undergoing assisted reproductive technologies.
