Filter by:Infertility affects about 10% of all couples and is defined by a failure to achieve a clinical pregnancy within a year of regular unprotected sexual intercourse. Up to one third of these couples will not have an identifiable cause after routine investigation, id est idiopathic infertility. The current diagnosis of male infertility relies on the World Health Organization (WHO) 2010 criteria which focus on concentration, motility and morphology in comparison to cut-off values of a fertile population. Alas, the relevance of the conventional semen analysis for the choice of treatment and the predictive value for an infertile couple with idiopathic or mild male infertility embarking on medically assisted reproduction (MAR) remains questionable. In other words, there is a strong clinical need to distinguish fertile from infertile men through new sperm function testing and to be able to select both the patient population who will benefit from MAR as well as the type of treatment. Numerous studies utilizing different techniques for assessing sperm DNA fragmentation support the existence of a significant association between sperm DNA damage and pregnancy outcomes. In this prospective cohort study the investigators aim to study the role of sperm DNA fragmentation analysis in selecting the patient who will benefit from intra-uterine insemination (IUI) therapy since IUI is still considered the first step in MAR and is performed at a large scale in Belgium and worldwide.
Accumulation of iron in patients with beta thalassemia major causes free radical formation which leads to damage of biological membranes. Sperm DNA damage may result from these generated antioxidants. We aimed at investigating the current DNA damage in the sperms of adult patients with beta thalassemia major and the effect generated by giving antioxidant treatment for 6 months.
Studies have shown that certain compounds inside vegetables can reduce the risk of cancer. Carrots in particular have an association with reduced incidence of colorectal, bladder and breast cancer. Compounds in carrots, called polyacetylenes, have been studied in isolated cells that have shown a reduction in cancer cells as well as inflammatory markers which have been associated with an increased risk of cancer. These polyacetylenes have not been well studied in the human body and it is unclear whether they are able to affect the biomarkers of health (disease) including DNA damage and inflammatory markers. The aim of this research project is to determine whether eating a portion of white carrots every day for 6 weeks can lead to a reduction in DNA damage and inflammatory markers compared to a control period of 6 weeks consuming a polyacetylene-free diet and a control food of a high fibre oat biscuit.
Obesity usually brings with it disturbances in the body that increase the chances of developing serious diseases like diabetes and cancer. These disturbances include one or more symptoms of a condition called "metabolic syndrome" that often leads to diabetes. High levels of damage to the DNA that makes up our chromosomes have also been observed in obese people. It is possible that these two disturbances are connected. The goal of this project is to test this whether consumption of blueberries will improve these abnormalities.
The purpose of this study is to determine whether couples undergoing IVF/ICSI with male factor infertility, specifically with elevated sperm DNA damage, should testicular sperm extraction be utilized to improve their reproductive outcomes.
The purpose of this study was to determine if noni juice reduces lipid hydroperoxide (LOOH) and malondialdehyde (MDA) derived-DNA adducts, markers of oxidative DNA damage, in peripheral blood lymphocytes of cigarette smokers.
The purpose of this study is to find a non-invasive way to discover DNA (deoxyribonucleic acid, which is the genetic material inside your cells) alterations in the sperm's head, in the near future leading us to choose the "good sperm" in a simplified manner. This could then increase chances of a successful in-vitro fertilization (IVF) treatment when there are sperm abnormalities.
The purpose of this study is to evaluate if the anesthetics propofol and isoflurane can damage DNA, induce apoptosis, change expression of genes related to apoptosis and DNA repair and change cytokines profile in patients submitted to elective surgery.
