Objective: To assess and compare the frequency of selected gene mutations of thrombophilic markers (FV Leiden, FII prothrombin G20210A and MTHFR C677T) in patients with primary and secondary infertility.
Design: Retrospective study.
Setting: Institute of normal anatomy, Faculty of Medicine and Dentistry, Palacky University Olomouc.
Methods: The study included 92 patients with primary infertility and 89 patients with secondary infertility. Indications for examination of these mutations were following: a positive family or personal history, a positive obstetrical history or a repeated failure of assisted reproduction treatment.
Results: According to our anticipation, women with the secondary infertility were significantly older(p < 0.0005) than those with primary infertility. No mutations of genes of examined thrombophilic markers (FV, FII and MTHFR), either alone or in combination, were found in only 8.7 % patients with primary infertility and in 5.6 % patients with secondary infertility. Significantly higher frequency of factor Leiden(p < 0.02) was observed in women with secondary infertility. There were no significant differences in the frequency of detected mutations of the remaining factors.
Conclusion: Based on our findings we suggest that the assessment of selected gene mutations of thrombophilic markers should be a part of the diagnostic algorithm in patients with positive history for thrombophilic disorders.

This narrative review intends to provide thorough information on the anti-inflammatory activities of plants, the largest genus of the family Zingiberaceae. The articles were searched on the PubMed database using 'Alpinia AND anti-inflammatory activity' as the keywords, filtered to articles published from 2020 to 2024 and free full-text. Of the approximately 248 members of the genus plants, the most commonly studied for their anti-inflammatory activities are , , , and .

The purpose of this study was to examine the deposition of advanced glycation end products (AGEs) and their receptors, RAGE, in ovarian follicles during folliculogenesis in mice fed high (H-AGE) or low (L-AGE) AGE diets and following superovulation with gonadotropins. We hypothesize that H-AGE diet is associated with increased AGE deposition and RAGE expression in various stages of ovarian follicular development, and superovulation with gonadotropins may alter these changes. C57BL/6J mice were fed low L-AGE (n = 10) or H-AGE (n = 10) diet for 12 weeks.

Introduction: Graft optimization is a necessity in order to develop uterus transplantation from brain-dead donors, as a complement to living donors, as these grafts are rare and the last organs retrieved in multiple organ donation. The aim of this study was to assess the feasibility and interest of hypothermic machine perfusion (HMP) in uterus transplantation using a porcine model; secondary outcomes were the evaluation of the graft's tolerance to a prolonged cold ischaemia time and to find new biomarkers of uterus viability.
Material And Methods: Fifteen uterus allotransplantations were performed in a porcine model, after 18 h of cold ischaemia, divided in three groups: Static cold storage in a HTK solution, HMP (with the VitaSmart (™) machine Bridge to Life Ltd.

Resveratrol can beneficially affect growth and follicle development and lead to improved sperm function parameters in pre-clinical studies, while information from clinical studies is still inconclusive. This study aims to evaluate the biological and clinical impact of a resveratrol-based multivitamin supplement on level II assisted reproduction cycles (IVF and intracytoplasmic sperm injection [ICSI]). A retrospective, case-control study, involving 70 infertile couples undergoing IVF/ICSI cycles, was conducted at the Assisted Reproductive Center, Obstetrics and Gynecology Unit-Villa Sofia-Cervello Hospital in Palermo.

Unlabelled: Infertility, both primary and secondary, is strongly influenced by microbiological factors, with the vaginal microbiota playing a key role in reproductive health.
Objective: The aim of this study was to characterize the vaginal microbiota of 136 Mexican women diagnosed with infertility-primary (n = 58) and secondary (n = 78)-by evaluating the presence of pathogenic bacterial species and their associations with infertility conditions.
Methods: Samples were obtained through cervical swabs, and microorganism identification was performed using qPCR techniques.
