Active clinical trials for "Infertility, Male"

Many cases of male infertility are poorly understood and regarded as unexplained. Therefore, a etiological treatment for this condition can not be offered in most cases. A beneficial effect on sperm motility was found in trails using antioxidants such as carnitine, zinc and folic acid. However, most studies lacked a sufficient power to detect a significant effect on pregnancy rates. In this study, infertile men with abnormal sperm quality parameters will be randomized to receive either carnitine-based food supplement (Porimore) or folate and Zinc Tablets.

Infertility has been estimated to affect from 6-18% of couples trying to conceive. In 20-30% of cases, the problem is with the male. Varicocele is a common cause of male factor infertility (MFI) being responsible for 30-35 % of primary and 69-81 % of secondary MFI. Varicocele repair has been shown to improve sperm parameters and increase natural pregnancy rates and the results of assisted reproductive techniques (ART). There are two possible treatment pathways for varicocele associated male factor infertility. 1) standard IVF/ICSI 2) varicocele repair followed by IVF/ICSI if there is no spontaneous pregnancy. There is however no consensus as to which pathway is preferable and no randomized comparative studies have been carried out. IVF/ICSI is a standard treatment for infertility but frequently requires repeated treatments to achieve a live birth. The purpose of this study is to determine if the improved sperm parameters caused by prior treatment of the varicocele will result in improvements both in overall pregnancy/birth rates and in IVF/ICSI results.

In this study, investigators assess, using Fluorescence in situ Hybridization (FISH) and Comparative Genomic Hybridization (CGH) arrays for Preimplantation Genetic Screening (PGS), the incidence of aneuploidies in spermatozoa and embryos from infertile men with and without microdeletions who undergo assisted reproduction in their clinics.

To evaluate embryology outcomes after application of a technique known as round spermatid injection (ROSI) into donor oocytes in a high-volume clinical infertility practice.

Setting. Outpatient fertility clinic. Aim. Investigate if a modification in nutritional habits may improve in the short term the qualities of human sperm, testing two hypothesis: i) that adding to the diet a natural whole food rich in polyunsaturated fatty acids (PUFA) OR ii) that reducing the intake of saturated fatty acids and increasing the consumption of PUFA may affect beneficially sperm parameters. Population. N. 100 hypofertile male subjects attending a fertility clinic. Type of study. Interventional study. No drugs or pharmacologic supplementation will be required nor allowed. Two different type of intervention are scheduled: Supplementation to western style diet with nuts, naturally rich in PUFA Diet modification increasing intake of PUFA-rich foods and cutting the consumption of food rich in saturated fats. Protocol Baseline visit and recruiting. Informed consent Randomized allocation to treatment group in a 1: 1 manner Blinding. Investigators deputed to sperm analysis and statistician are blinded as to type of intervention. Phases: i) basal ii) after 15 weeks That interval is chosen because encompasses an entire spermatogenesis cycle. Outcomes. Primary sperm count, concentration,morphology and mobility. Secondary: serum folate assay, plasma PUFA (ALA, EPA, DHA) assay, body weight and BMI variation Statistics. A comparison for all sperm parameters (count,concentration,morphologic abnormalities, mobility) will be carried out by an analysis within groups and within patient.

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

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 purpose of this randomized clinical trial is to assess the effect of oral antioxidant administration to infertile men, by evaluating semen variables, sperm DFI and levels of ROS. Oral antioxidants or placebo will be given for 3 consecutive months. The study will recruit infertile men, who have one previous abnormal spermiogram, with at least one pathological variable (concentration, motility, morphology), according to WHO 2010 criteria. Participants will be recruited in the outpatient clinic of the Unit of Human Reproduction and of the Unit of Reproductive Endocrinology at the 1st Ob/Gyn Dept.

Investigators have previously found that sperm quality was not related to obesity indicators, such as body mass index (bmi), waist circumference, waist-hip ratio, girth ratio and serum lipid, but seminal plasma lipids could notably affect the sperm concentration, sperm progressive ratio(PR), sperm DNA fragmentation index (DFI). These results indicates that abnormal lipid metabolism in the male reproductive system may affect male fertility. It seems that the sperm fatty acid spectrum is associated with n-3 polyunsaturated fatty acids (PUFA) in dietary. Docosahexaenoic Acid (DHA) and Eicosapentaenoic Acid (EPA) are the most common n-3 PUFA. Only plasma DHA/EPA may reflect the quantity of DHA/EPA in adults. Most research indicate that n-3 PUFA is the main polyunsaturated fatty acid in human sperm. It is well known that diets have great influence on the gut microbiota composition. Many researches have delineated the cause and effect relationship between disturbed gut microbes and diseases, such as irritable bowel syndrome, obesity, diabetes. The disturbed gut microbiota ecosystem may also lead to the intestinal mucosal permeability increasing, which may result in endotoxemia and a series of metabolic syndrome. N-3 polyunsaturated fatty acids may play an important role in regulating metabolism and physiological functions in the body. A clinical research found that both total n-3 PUFA and DHA serum levels were significantly correlated with microbiome alpha diversity. Therefore, investigators may try to figure out the influence of n-3 PUFA supplement on gut microbiota composition and whether the gut microbiota have influence on sperm parameters. So investigators apply for your permission to collected the fecal samples from the participants, which will be a meaningful work.

This study is a prospective double blind randomized controlled trial to investigate the effect of red and white bahman on semen parameters, sexual hormones and DNA defragmentation in idiopathic oligospermic men .Include patients will take the medicine and placebo in different two case and control groups for 3 month and semen parameters and other variants at the start and end of study.
