主 题:male fertility pericentric inversion of chromosome 9 sperm bank sperm functional parameters
摘 要:Pericentric inversion of chromosome 9(inv[9])is a common chromosomal structural variant,but its impact on clinical outcomesremains *** screening criteria of sperm banks are rarely mentioned to individuals with inv(9).In this study,we evaluatedthe fertility of sperm donors with inv(9)who met eligibility criteria for sperm banks(inv[9]-eligible donors).From March 2004 toMay 2022,chromosomal analysis of 16124 sperm donors at CITIC-Xiangya Human Sperm Bank in Hunan Province(Changsha,China)found that 251(1.6%)had chromosome variations,with inv(9)being the most prevalent at 1.1%.All 169 inv(9)-eligibledonors were contacted to collect fertility outcome data,along with 206 eligible donors without inv(9)as *** addition,semen samples from inv(9)-eligible donors and eligible donors underwent assessments of sperm fluorescence in situ hybridization(FISH),mitochondrial membrane potential,DNA fragmentation index,acrosome integrity,reactive oxygen species(ROS),andsperm *** showed that inv(9)did not significantly increase reproductive risks *** detecting ROSlevel differences,the clinical impact may be *** study provides new data on the inv(9)population that can serveas a valuable reference for decision-making by sperm banks as well as for genetic counseling and clinical guidance for individualscarrying inv(9)variant.
