Evaluation of DNA damage in human spermatozoa: a sperm quality assay.
2008
Several studies have demonstrated the relationship between gonadotrophine serum levels and the apoptosis rate in germinal cells. In human, lower FSH serum levels are associated with reduced Sperm Standard Parameters in term of concentration, motility and morphology and higher sperm DNA fragmentation. Hypogonadotrope hypogonadism is a clinical condition associated with male infertility, characterized by low serum levels of gonadotrophins. In this pilot study we investigated the spermatozoa quality of 11 patients with development of hypogonadotrope hypogonadism urdergoing in vitro fertilization programs. Recombinant-FSH administered to improve the sperm parameters, apoptosis rate, aiming to i…
Potential role of p53 protein as a novel biomarker of sperm quality, able to predict the success of ART techniques. EcoFoodFertility Project
2018
Introduction: Protein p53 is well known as “The guardian of genome”; it changes its concentration in human spermatozoa DNAin relation to the damage of the latter. It has been suggested thatthe role of the p53 ancestral gene was to ensure the integrity ofthe genomic germline and the fidelity of the evelopment process.The aim of this study is to evaluate if different concentrations of p53 protein in human spermatozoa could influence embryo quality and pregnancy rate and possibly representing a potential predictive marker of sperm quality for successful fertilization .Methods: From July 2013 to June 2017 we have examinatedretrospectively 79 couples with 2-5 years of infertility history.Males had…
