Filter by: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.
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.
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.
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.
