Embryo transfer is the most emotional part for patients during fertilization treatment. Over the last decade, the embryo transfer procedure has undergone numerous changes in the guidelines in order to increase pregnancy rates. One such procedure is the loading of the embryo into the catheter, a thin tube that helps us transfer embryo into the uterine cavity. Very few research studies looked closely at embryo-loading technique per se. Furthermore, different infertility laboratories use various techniques to load embryo. The aim of our study was to compare the two most popular embryo-loading techniques. In 249 women, we transferred embryo aspirated into the catheter with small droplets of air, and in the group of 244 patients, we filled catheter only with fluid. Our main outcome measured was the clinical pregnancy rate. Based on our results, we did not find that embryo-loading technique affected patient's chances of achieving pregnancy.

Uterine pathology and microbiome among patients with endometrial polyps and fibroids.
F S Sci
December 2024
Division of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, Northwestern University Feinberg School of Medicine, 259 E Erie St Suite 2400, Chicago, IL 60611, USA; Division of Reproductive Endocrinology and Infertility, Department of Obstetrics and Gynecology, Warren Alpert Medical School of Brown University, 101 Dudley St., Providence, RI 02905, USA.
Objective: To evaluate the uterine microbiome among women with endometrial polyps and submucosal fibroids and to compare results between endometrial sampling techniques.
Design: Patients with polyps or fibroids were prospectively recruited prior to hysteroscopy, while patients undergoing retrieval for planned oocyte cryopreservation were recruited prospectively as controls. Three specimen types obtained for each patient were the distal 5 mm of an embryo catheter passed to the uterine fundus (C), endometrial tissue from an endometrial biopsy (T), and formalin fixed paraffin embedded endometrial tissue from the same endometrial biopsy (FFPE).
Determining Factors Influencing The Successful Embryo Transfer and Pregnancy during The Frozen Cycle of Fertilization: A Retrospective Cohort Study.
Int J Fertil Steril

Department of Obstetrics and Gynecology, Faculty of Medicine, Chulalongkorn University, Bangkok, Thailand.
Background: Frozen embryo transfer (FET) has been increasingly used due to advancements in cryopreservation techniques and the safety advantages. This study aims to determine various factors influencing the successful FET.
Materials And Methods: Retrospective cohort analysis included 1112 women who underwent programmed FET between January 2012 and October 2022, at King Chulalongkorn Memorial Hospital, Thailand.

A successful embryo implantation relies heavily on the receptivity of the endometrial epithelium, a process regulated by various molecular mechanisms. Evaluating endometrial receptivity in infertility patients undergoing assisted reproductive treatment, particularly those with adenomyosis related infertility, poses significant challenges due to limitations associated with conventional assessment methods. In this study, we collected residual endometrial epithelial cells from the tips of embryo transfer catheters in patients with adenomyosis related infertility.

Article Synopsis
- The study examines the use of fetal heart quantification (HQ) technology to assess the size and function of the hearts of fetuses diagnosed with fetal growth restriction (FGR) compared to healthy controls.
- Results show that fetuses with FGR had significantly smaller heart dimensions and varied function metrics, particularly in the left and right ventricles, indicating impaired cardiac development.
- The analysis also highlights differences in heart function based on the timing of FGR onset, with early-onset cases showing more pronounced abnormalities than late-onset cases.
Is there any difference in Lactobacillus abundance between age groups during ovarian stimulation in fresh in vitro fertilization (IVF) cycles?

Institute for Human Reproduction "Dr. Balić", Tuzla, Bosnia and Herzegovina.
Aim: To investigate an influence of age and body mass index (BMI) as determinants of infertility treatment success in vitro fertilization (IVF) procedures confirmed so far, on the amount of Lactobacilus spp. (LS) and Gardnerella vaginalis (GV) in the endometrium in fresh IVF cycles at the time of embryo transfer.
Methods: This a prospective single-centre study included patients who underwent fresh embryo transfer (ET) in a private IVF Centre.
