Objective: To evaluate whether a combination of IUI and frozen-thawed embryo transfer (FT-ET) with ovulation induction would improve the PR in couples with unexplained infertility.
Design: Prospective, randomized study.
Setting: In Vitro Fertilization Unit, Tel Aviv Sourasky Medical Center, Tel Aviv, Israel.
Patient(s): Sixty-two patients with unexplained infertility were assigned into two groups. The study group was composed of 32 women (38 cycles) who received ovulation induction followed by IUI and FT-ET. The control group was composed of 30 women (33 cycles) who received ovulation induction followed by FT-ET.
Intervention(s): Clomiphene citrate (CC) and hCG, IUI, and FT-ET.
Main Outcome Measure(s): Pregnancy rate (PR) per cycle, PR per ET.
Result(s): In the study group, the PR per cycle and per ET were 36.8% (14 of 38) and 40.6% (13 of 32), respectively. In the control group, the PR per cycle and per ET were 12.1% (4 of 33) and 14.3% (4 of 28), respectively. Statistically significant differences were found between the two groups in the PR per cycle (P=.02) and PR per ET (P=.03). No statistically significant difference was found between the groups for the stage in which the embryos were cryopreserved, the survival cleavage rates after thawing, grading of thawed embryos, and number of embryos transferred.
Conclusion(s): In couples with unexplained infertility, the PR may be improved by combining IUI and FT-ET with ovulation induction. Performing IUI before thawing may prevent treatment cancellation in cycles with no surviving embryos.

Background: Overweight and obesity-chronic illnesses in which an increase in body fat promotes adipose tissue dysfunction and abnormal fat mass resulting in adverse metabolic, biomechanical, and psychosocial health consequences-negatively impact female fertility. Adverse conception outcomes are multifactorial, ranging from poor oocyte quality and implantation issues to miscarriages and fetal health issues. However, with the advent of novel pharmacologic agents, significant weight loss can be achieved, improving the chances of healthy pregnancies, and their use should be considered during periconceptual counseling.

Aim: This study aims to assess the impacts of various trigger day progesterone (P) and luteinizing hormone (LH) levels on live birth rates (LBRs) in fresh in vitro fertilization (IVF) cycles, considering their elevation from stimulation and premature luteinization.
Methods: This retrospective cohort study included the first ovarian stimulation cycles with GnRH antagonist protocol of 1253 patients who underwent intracytoplasmic sperm injection and fresh embryo transfer at a tertiary clinic's IVF center between 2010 and 2016. Participants were divided into four groups based on trigger day serum P and LH levels, using the 90th percentile thresholds for P (1.

For commercial laying hens, the continuous high-intensity ovulation process leads to a significant accumulation of reactive oxygen species (ROS) in the granulosa cells, inducing oxidative stress, which accelerates ovarian aging and shortens the peak laying period. The molecular mechanisms underlying this process remain poorly understood. Therefore, we modeled the processes of oxidative stress and antioxidant in chicken granulosa cells.

Combined oral contraceptives (COCs) are widely used by reproductive-aged women. Current data suggest that long-term use of COCs can suppress ovarian reserve markers, including anti-mullerian hormone and antral follicle count, which may negatively impact ovarian response and oocyte yield in patients undergoing planned oocyte cryopreservation to preserve future reproductive potential. Discontinuation of COCs can improve ovarian stimulation outcomes, though the ideal duration of cessation is unknown.

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.
