Filter by:The prognosis in cancer patients has improved over the years. Survivor rates have increased significantly, and paternity has become an important concern in more than 50% of young male survivors. Sperm cryopreservation before cancer treatment is highly recommendable in these patients, as a strategy to preserve their fertility due to is not possible to predict how the chemo or radiotherapy treatment will affect the spermatogenesis. The objective of this study is to evaluate if sperm after an antineoplastic treatment can be safely used. To determine the possible effects of oncological treatments in the spermatogenesis, three parameters will be analyzed, aneuploidy frequencies, DNA fragmentation in single and double-strand breaks and methylation levels to determine epigenetic changes before and after the therapy. If cancer treatment affect sperm genetic integrity, it would have a clinical impact in the offspring of these patients. Identify the different side effects of antineoplastic treatments in DNA sperm will provide a clinical improvement in order to select the best sperm sample in an IVF treatment and it will facilitate genetic counseling
Infertility is a major health problem affecting up to 15% of couples of reproductive age globally. For several years, it was assumed that most reproductive problems could be attributed to the female partner, but research in recent years has demonstrated that males were solely responsible for 20-30% of infertility cases and contributed to 50% of infertility cases overall. The term ''male infertility'' does not constitute a defined clinical syndrome, but rather a collection of different conditions exhibiting a variety of etiologies. It is far increasingly known that reactive oxygen species (ROS) are of significant pathophysiological importance in the etiology of male infertility. ROS are highly reactive oxidizing agents belonging to the class of free radicals containing one or more unpaired electrons, which are continuously being generated through metabolic and pathophysiologic processes. It has been suggested that oxidants interfere with normal sperm function via membrane lipid peroxidation and fragmentation of nucleic acids, which result in sperm dysfunction. Due to the sperm cell membrane abundance of polyunsaturated fatty acids (PUFAs) and the capacity of sperm to generate ROS, human spermatozoa are highly susceptible to oxidative stress. Since growing evidence indicates that oxidative stress can be a primary cause of male infertility, non-enzymatic antioxidants play a significant protective role against oxidative damages and lipid peroxidation. In addition, micronutrients and antioxidants are often used with good results in men with idiopathic infertility. Keeping in view the main protection provided by seminal plasma antioxidants against oxidative damages, a previous study showed that the dietary management with an eight nutritional supplements' combination, similar to this study's product and containing antioxidants, achieved a significant improvement in sperm quality up to a completely normal semen analysis. Also, another study confirmed the hypothesis that the combination of individual nutritional supplements as described in literature showed significantly better results than the sum of the effects of single administration.
This aim of this study is to determine the impact of lifestyle on telomere length and telomerase enzyme activity on sperm cells of men undergoing IVF treatments.
Microfluidic chips are one of the methods of sperm separation to eliminate DNA fragmentation in sperm. It is thought that the separation of sperm by centrifugation in the classical gradient density (Percoll) method used in sperm separation in IVF and IUI cycles leads to the increase of reactive oxygen radicals in sperm and this leads to sperm DNA fragmentation. Studies comparing Percoll and microfluidic chip method in terms of sperm, embryo quality and pregnancy rates are limited. In this context, it is aimed to investigate the effect of Percoll or Microfluidic Chip Technology on the quality of sperms and embryos obtained with these sperms and their pregnancy rates prospectively.
The aim of this randomized controlled trial is to compare the efficacy of oral dydrogesterone vs. micronized vaginal progesterone for luteal phase support in frozen-thawed embryo transfer cycles.
Recent studies have evaluated the use of magnetic-activated sperm sorting (MASS) to reduce apoptotic spermatozoa and improve the outcome of infertile male with assisted reproductive technology (ART). However, some results were inconsistent with above. The sperm of male with abnormal semen analysis tend to be accompanied with high apoptotic and high DNA fragmentation index (DFI). Hence, this study aimed at determining the efficiency of MASS in improving the clinical outcome of patients with high DFI).
The objective of this study is to evaluate the impact of the Genante(TM) on the spermiogram parameters in infertile male patients
The purpose of this study will be to investigate if there is a correlation between Vitamin D levels and Sperm DNA Fragmentation. This is a prospective, cohort study. In this study male participants presenting with their partners because of inability to conceive will be recruited for this study. Participants will have a blood sample drawn which will be tested for Vitamin D level. The investigators will then compare sperm DNA fragmentation between normal Vitamin D levels, Vitamin D insufficiency, and Vitamin D deficiency. All infertile males who present to the investigators' infertility clinic have a Semen analysis and Sperm chromatin Structure Assay (SCSA). The research part of the study will be to obtain the Vitamin D level.
The aim of this study is to evaluate if Myo-inositol, N-Acetyl-Cysteine plus a cocktail of antioxidants could be able to increase spermatozoa parameters and reduce semen hyper-viscosity
Infertility affects approximately one in seven couples, and it can be a devastating diagnosis and difficult experience for couples to endure. Ellen Langer, Ph.D., Director of the Langer Lab at Harvard, has spent several decades demonstrating evidence supporting a mind-body approach to improve wellbeing and overall functioning. Specifically, she asserts that Mindfulness in its most basic sense - paying attention in the moment - is enough to create both perceived (e.g., self-reported) and real (e.g., objective testing) change. Langer and her colleague, for example, demonstrated that "Trait mindfulness predicted the well-being of expecting mothers and better neonatal outcomes. Mindfulness training resulted in better health for the expecting mother". In this study, Mindfulness training refers to "attention to sensation variability." Such interventions are cost effective, minimally invasive, less time-consuming for practitioners and participants and generally easy to learn. Langer and her colleague's study refers to pregnancy. Infertility is unlike pregnancy in its exact clinical diagnosis. Nevertheless, similar to pregnancy, infertility is considered a clinical condition affecting the body, in this case the reproductive system. Therefore, based on the results of studies like Langer and her colleague's, that used participants with clinical conditions affecting the reproductive system, the investigators propose similar mindfulness intervention (attention to sensation variability) research with infertile individuals. However, the investigators intend to extend our examination to also include a treatment group with the partners of the infertile individuals, as little, if any research, has attempted to do so previously. The investigators hypothesize that state mindfulness (groups exposed to mindfulness intervention) will improve wellbeing in the infertile patient and her partner and that trait mindfulness will predict ability to become pregnant.
