Qsox2 deletion did not affect the testicular structure or sperm production in mice. A Histological analysis showed that compared with control mice (Sox-Qsox2 ^+/+), Qsox2 knockout (Sox-Cre Qsox2 ^−/−) did not affect the testicular structure as the multi-layer spermatogenic structure was still visible in the testicular section, and the epididymal lumen (caput) was filled with sperm cells. B Testicular weight and sperm concentration did not differ between control and Qsox2 knockout mice, supporting the notion that Qsox2 knockout did not affect testis and sperm production in male mice. N.S.: non-significant
