TEX15 and Infertility: Given recent studies (Aston, 2014; Zhang et al., 2015; Tüttelmann et al., 2018; Cerván-Martín et al., 2020; Cioppi, Rosta, and Krausz, 2021; Ghadirkhomi et al., 2022; Guzmán-Jiménez et al., 2022), we also sought to determine if TEX15 polymorphisms could be used as markers for infertility; however, given that the identified polymorphisms (see Materials and Methods) appeared at the expected frequency among both our control and affected populations, we found no apparent, statistically significant relationship between TEX15 polymorphisms and SPGF.
