Background: Non-obstructive azoospermia (NOA), the severe type of male infertility. The objective of this study was to evaluate the predictive accuracy of a prediction model of sperm retrieval failure with fine needle aspiration (FNA).
Methods: This study involved 769 NOA patients (dataset 1) undertaking FNA and 140 NOA patients undertaking mTESE (dataset 2).

Purpose: Previous studies have suggested a link between serum progesterone levels on the day of the HCG trigger in IVF cycles and oocyte and embryo quality. This study aims to explore this relationship more thoroughly.
Methods: This study included 496 infertility patients at Moloud Infertility Treatment Center, Zahedan, Iran.

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.

Purpose: This study aims to explore the impact of a woman's previous cesarean delivery (CD) on pregnancy and neonatal outcomes for subsequent in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI) and single frozen-thawed embryo transfer (FET), compared with vaginal delivery (VD).
Methods: This was a retrospective cohort study that included a total of 5817 patients who desired to transfer a single vitrified-thawed blastocyst from the same oocyte retrieval cycle as their last live birth between January 2011 and January 2021 at a single reproductive medicine center. Patients with a single previous CD were classified in the CD group, while those with a single VD were assigned to the VD group.

Objective: To study the reliability and effectiveness of the percutaneous sperm retrieval technique.
Methods: We retrospectively analyzed the records of 123 consecutive patients with obstructive azoospermia who underwent percutaneous sperm retrieval and intracytoplasmic sperm injection (ICSI) using Percutaneous Epididymal Sperm Aspiration (PESA) with or without a rescue Testicular Sperm Aspiration (TESA). We compared patients who had the first sperm retrieval ever and patients who had more than one sperm retrieval performed.
