Researchers usually use chemical drugs to directly damage germ cells to prepare oligoasthenospermia models, which disregards the adhesion and migration between spermatogenic cells and Sertoli cells. <jats:italic>TAp73<\/jats:italic> is a critical regulator of the adhesin of germ cell; thus, we sought to explore a novel oligoasthenospermia model based on <jats:italic>TAp73<\/jats:italic> gene suppression.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>Mice in the Pifithrin\u2010\u03b1 group were injected intraperitoneally with 2.5\u00a0mg\/kg Pifithrin\u2010\u03b1 (<jats:italic>TAp73<\/jats:italic> inhibitor) daily for 30 consecutive days.
