Active clinical trials for "Teratozoospermia"

The object of study for patients with idiopathic disease of OAT, the use of multicenter, randomized, double-blind, controlled, prospective clinical research, choose according to row, standard units of idiopathic male infertility clinics less weak abnormal sperm, randomly divided into experimental group and the placebo group, the comparison between the two groups of patients and semen parameters before and after medication, seminal plasma hormone, serum lipid levels and other indicators;At the same time, serum and seminal plasma samples of the two groups of patients before and after treatment were collected for bioinformatics analysis of protein spectrum to find the effector molecules of Gulingji capsule.

This is a multicenter, case-control study that aims to investigate the relationship between microbiota and sperm quality via stool, blood, and urine microbiome, metabolomics, and collected clinical metadata. The results of the spermatogenic dysfunction, including aspermia, oligozoospermia, asthenozoospermia, and teratozoospermia, will be compared to normal basic semen analysis utilizing the World Health Organization (WHO) semen analysis procedure 5th edition.

This is a randomized controlled trial to evaluate the effect of ramipril in stimulating and promoting sperm production in men with low sperm count. Ramipril is an Angiotensin Converting Enzyme Inhibitor (ACEI) currently used to treat high blood pressure. However, previous studies have shown that this class of medications can improve sperm parameters. The purpose of this study is to evaluate the efficacy of ramipril compared to placebo (Substance That is not known to have treatment effect), in improving sperm density in infertile men with documented low sperm count. This study will help us identify subjects that might benefit from treatment with this medication, and the effect it will have on sperm count, shape, and motility.

Purpose: To compare the effects of the density gradient centrifugation and microfluidic chip sperm preparation methods on embryo development in a study population with astheno-teratozoospermia. Materials and Methods: In this prospective study, the semen samples of the patients with astheno-teratozoospermia were divided into two groups for preparation with either the microfluidic or density gradient methods. Selected spermatozoa were used to fertilize the mature sibling oocytes. Semen parameters and embryo development on days 3 and 5 were assessed.

The investigators are testing the hypothesis that two ounces of whole-shelled walnuts/day added to the diet of men seeking care for infertility will beneficially affect sperm parameters and fertility. The investigators will compare the walnut intervention to the commonly suggested recommendation of adding an OTC multivitamin supplement to the diet.

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.

Lifestyle and environmental factors can disrupt development and testicular function. In France, cannabis is the most widely used illicit substance and about 8% of adults between 18 and 64 years smoke cannabis at least once a year, and mostly men under 45 years. Endocannabinoids are lipid mediators that share some effects with the active ingredients of cannabis. Cannabis and endocannabinoids act via two types of endogenous receptors which were detected at different levels of the reproductive system and are involved in the central and local regulation of the gonad. Cannabis use may alter the normal regulation of the endocannabinoid system. In males, the regulation of the endocannabinoid system is critical for Sertoli and Leydig cells functions, germ cell differentiation, maturation of sperm nucleus and sperm quality. The cannabis can have a negative impact on sperm parameters, capacitation and acrosome reaction. Cannabinoids may decrease testosterone synthesis and induce apoptosis of Sertoli cells. Studies on the effect of cannabinoids on male fertility are scarce or nonexistent in infertile men because of ethical considerations and bias due to consumption often underreported. Investigators hypothesized that cannabis use may alter sperm nuclear quality. Investigators want to explore this hypothesis conducting a multicentric prospective study exposed/non-exposed in infertile men who are consulting for Medically Assisted Reproductive Technologies (ART). To reach this study, it is planned to include a total of 200 subjects taking into account any exclusions.

Women over 35 years old are likely to suffer from impaired oocyte repair capacity. Teratozoospermia is a condition reflects morphological affection of sperm. These spermatozoa would add an extra burden on the oocyte after ICSI. Whether selecting mature sperm by magnetic nanoparticle protocol would provide a more competent sperm to a likely affected oocyte would improve ICSI outcomes is the question of this research.
