Objective: To evaluate the efficacy of ovulation stimulation protocol with gradual increment of gonadotropin in women with high ovarian response.
Methods: A retrospective study was conducted between june 2005 and April 2006 in 70 women undergoing controlled ovarian hyperstimulation. The clinical outcomes of the women using gradual increment protocol were compared with those of women receiving other ovulation-stimulating protocols.
Results: The mean number of large follicles (>or=14 mm) and retrieved oocytes on the day of retrival was significantly lower, but the duration of stimulation was significantly longer in the gradual increment group than in the control group. The rate of follicular puncture was also higher in the former group. The clinical pregnancy rate, total gonadotropin dosage, cancellation rate and incidence of ovarian hyperstimulation syndrome were similar for the two groups.
Conclusion: Ovulation stimulation protocol with gradually increased gonadotropin may provide a promising alternative for controlled ovarian hyperstimulation in women with a strong ovarian response.

Objective: To build a prediction nomogram for early prediction of live birth probabilities according to number of oocytes retrieved in women ≤ 35 years of age.
Methods: A prediction model was built including 9265 infertile women ≤ 35 years of age accepting their first ovum pick-up cycle from January 2018 to December 2022. Least absolute shrinkage and selection operator (LASSO) regression was performed to identify independent predictors and establish a nomogram to predict reproductive outcomes.

Background: There are limited and controversial findings concerning ovulation induction using intrauterine and intramuscular human chorionic gonadotropin (hCG) injection compared to intramuscular hCG alone. The study aimed to examine the impact of intrauterine hCG injection, which is used to induce ovulation, on the efficacy of the intrauterine insemination (IUI) technique in patients with unexplained infertility.
Methods: A randomized controlled clinical trial was conducted involving 80 subjects with unexplained primary infertility at the infertility clinic of Al-Zahra Hospital in northwest Iran.

Follicle-stimulating hormone (FSH) and luteinizing hormone (LH) are mainly involved in follicle development and ovulation, but FSH receptor (FSHR) and LH receptor (LHR) are also expressed in the immune system. Nevertheless, it is not clear if gestation affects the expression of the FSHR and LHR in the maternal main immune organs (thymus, lymph node, spleen, and liver). In this study, these organs were sampled from the ewes at the estrous cycle, and during early pregnancy, and mRNA and protein expression of FSHR and LHR were analyzed.

Objectives: This study aimed to investigate the correlation of ovarian sensitivity index (OSI) and clinical parameters in IVF treatments.
Methods: IVF data files between January 2011 and December 2020 in a single unit were included. The primary outcome measure was the correlation between the OSI and clinical pregnancy and live birth rates.

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.
