Background: Induced endometrial injury is a technique described that have positive impact on implantation. The aim of this study was to investigate whether hysteroscopic endometrial fundal incision (EFI) in oocyte recipients before embryo transfer increases pregnancy and live birth rates or not.
Materials And Methods: A prospective study was conducted between 2014 and 2019 at an fertilization (IVF) unit in Greece. As part of the protocol, hysteroscopy and EFI were offered to all the egg recipients and the outcomes compared with those from an older cohort from the same Unit not undergoing hysteroscopy.
Results: In total, 332 egg recipients participated in the study; 114 of them underwent EFI prior to embryo transfer. Both groups were similar in terms of age, years of infertility, duration of hormone replacement treatment (HRT) and number of blastocysts transferred. In the EFI group, minor anomalies were detected and treated in 6.1% (n=7) of the participants. Moreover, pregnancy test was positive in 73.7% of the women in the hysteroscopy group compared to 57.8% in the nonhysteroscopy group (P=0.004). Live birth rate was also higher (56.1 vs. 42.2%, P=0.016) in the EFI group compared to the non-hysteroscopy one.
Conclusion: Apart from the obvious benefit of recognizing obscured anomalies, requiring surgical correction, it appears that in oocyte recipients prior to embryo transfer, EFI might improve uterine receptivity and reproductive outcomes.

Objective: This study aimed to develop a predictive model for the risk of no usable blastocyst formation in patients with normal ovarian reserve undergoing IVF.
Methods: The model was derived from 7,901 patients who underwent their first oocyte retrieval and subsequent blastocyst culture, of which 446 cases have no usable blastocysts formed. Univariate regression analyses, least absolute shrinkage and selection operator regression analysis were used to identify the association of patient and cycle characteristics with the presence of no available blastocyst and to create a nomogram.

Endometrial organoids (EOs) are three-dimensional models that emulate the endometrium, serving as an invaluable in vitro tool for investigating the cellular and molecular mechanisms underlying endometrial physiology and pathology during the estrous cycle and pregnancy. While significant progress has been made in the establishment and optimization of EOs for both humans and mice, research on such models in other species remains limited. This study aimed to develop porcine endometrial epithelial organoids (EEOs) to explore the regulatory mechanisms of uterine function and maternal-fetal interactions during porcine pregnancy, which are critical for enhancing reproductive efficiency and improving embryo transfer techniques.

Purpose: To evaluate the performance of different embryo transfer (ET) operators in a strictly controlled scenario minimizing potential confounders.
Methods: This single-center retrospective cohort study analyzed vitrified-warmed single euploid top-quality day-5 blastocyst transfers performed in non-obese women at the same IVF center by four equally trained clinicians using a standardized ET technique. These strict inclusion criteria allowed excluding all main confounders on the primary study outcome, namely clinical pregnancy rate (CPR) per ET across different operators.

Familial Mediterranean fever (FMF) is an autoinflammatory disease characterized by periodic fever, serositis, and arthritis. In women, FMF attacks can sometimes be triggered by the menstrual cycle. Once diagnosed, prophylactic treatment with colchicine is generally recommended.

Purpose: The number of frozen-thawed embryo transfers (FETs) has recently increased, and FET must be completed in the ovulatory (NC-FET) or programmed hormone replacement cycle (HRC-FET). However, the relationship between FET and abnormal placentation is unclear. This study aimed to determine whether the two distinct endometrial preparation protocols affect the incidence of several pathologic conditions caused by abnormal placentation, such as placenta with velamentous umbilical cord insertion (VCI), hypertensive disorders of pregnancy (HDP), and placenta accreta spectrum (PAS).
