The occurrence of vaginal discharge in postpartum dairy cows is generally diagnosed as clinical endometritis. This uterine condition is associated with reduced fertility and economic loss for the dairy industry. Therapeutic approaches include the systemic or intrauterine application of antibiotics or the injection of prostaglandin F2α and analogues to cause luteolysis and uterine contractions to evacuate the infected content. The treatment of clinical endometritis remains a subject of considerable controversy in the literature. Better understanding of the reproductive biology of normal versus abnormal uterine involution and immune mechanisms will allow more efficient diagnostic methods and a more efficient therapeutic approach.

Purpose: To evaluate the effect of endometrial scratching on in vitro fertilization (IVF) success rates in women undergoing frozen embryo transfer with preimplantation genetic testing for aneuploidy (PGT-A).
Methods: Biopsy was performed at oocyte retrieval in cases and compared to those who did not undergo scratching (controls). Endpoints included pregnancy loss, total pregnancy, clinical pregnancy rate (CPR), ongoing pregnancy rate/live birth rate (OPR), and the incidence of chronic endometritis (CE).

Objective: This study aimed to evaluate the safety and efficacy of vacuum-induced intrauterine balloon tamponade (vIBT) using the modified Bakri system in a clinical setting.
Materials And Methods: This single-center observational study included women who had undergone vIBT for primary postpartum hemorrhage (PPH). Vacuum induction at 60 kPa in the uterus was continued for 1 h with 50-100 ml saline, and the balloon was promptly removed after the protocol was completed.

Background: Embryo implantation involves two key elements: a good quality embryo and receptive endometrium. Endometrial receptivity abnormalities are known as one of the possible causes of recurrent implantation failure (RIF), especially when the embryo is euploid. This study was aimed to evaluate the impact of age and other clinical factors on endometrial receptivity in women with RIF.

Introduction: Endometritis is a very common pathology in animals which changes endometrial leukotriene (LT) formation and muscarinic 2 and 3 receptor subtypes (M2R/M3R) and α-7 nicotinic acetylcholine (ACh) receptor (α-7 nAChR) expression patterns. With the relationship between ACh, its receptors and LT production remaining unclear, the role of M2R, M3R and α-7 nAChR in action of ACh on the 5-lipoxygenase (5-LO), LTA4 hydrolase (LTAH) and LTC4 synthase (LTCS) protein abundances in the inflamed porcine endometrium and on the tissue secretion of LTB4 and LTC4 were studied.
Material And Methods: On day three of the oestrous cycle in gilts aged 7-8 months, 50 mL of either saline solution (control group, n = 5) or an suspension at 10 colony-forming units/mL ( group, n = 5), was injected into each uterine horn.

To explore the impact of gonadotropin-releasing hormone agonist (GnRH-a) on the pregnancy outcomes in frozen-thawed embryo transfer cycles for patients with recurrent implantation failure (RIF) complicated by chronic endometriti (CE). A total of 138 patients with RIF combined with CE who underwent in vitro fertilization/intracytoplamic sperm injection treatment-embryo transfer in the Department of Reproductive Medicine, Beijing Obstetrics and Gynecology Hospital, Capital Medical University from January 2020 to December 2023 were retrospectively included. According to the endometrial preparation protocol, they were divided into two groups: the pituitary downregulation group (=59) and the artificial cycle group (=79).
