NCT ID: NCT06231589 Completed - Infertility Clinical Trials

PGT-A Evaluates Advanced Sperm Selection in Embryos From High Teratozoospermia Males

Start date: January 1, 2023
Phase: N/A
Study type: Interventional

In this study of 264 couples, sperm selection techniques in males with high teratozoospermia index and sperm DNA fragmentation significantly increased fertilization, blastocyst development rates, and maintained comparable embryo euploidy rates through preimplantation genetic testing, suggesting the efficiency of these techniques in improving assisted reproductive outcomes.

NCT ID: NCT05628987 Recruiting - Infertility, Male Clinical Trials

The Association of Gut Microbiota and Spermatogenic Dysfunction

Start date: February 20, 2023
Phase:
Study type: Observational

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.

NCT ID: NCT05320536 Recruiting - Oligospermia Clinical Trials

A Clinical Study of Gulingji Capsule in the Treatment of Idiopathic Oligospermia, Asthenia, and Teratozoospermia

Start date: December 6, 2021
Phase: Phase 4
Study type: Interventional

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.

NCT ID: NCT04962074 Completed - IVF Clinical Trials

Sperm Selection and Embryo Development: Comparison of the Density Gradient Centrifugation and Microfluidic Chip Sperm Preparation Methods Sperm Selection and Embryo Development: Comparison of the Density Gradient Centrifugation and Microfluidic Chip Sperm Preparation Methods

Start date: January 5, 2020
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT03666364 Completed - Infertility Clinical Trials

Magnetic Nanoparticle Sperm Separation for Teratozoospermia Male and Women Older Than 35 Years

Start date: September 17, 2018
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT02932527 Recruiting - Teratozoospermia Clinical Trials

Effect of Cannabis Consumption on Sperm Nuclear Quality in Infertile Men

CANNASPERM
Start date: August 29, 2017
Phase: N/A
Study type: Interventional

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.

NCT ID: NCT01954498 Completed - Fertility Clinical Trials

Effect of Walnuts on Sperm Parameters and Male Fertility

Start date: May 2014
Phase: N/A
Study type: Interventional

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.
