Objective: Based on the mitochondrial pathway, the effects of Zhibai Dihuang Decoction containing serum on apoptotic cells of spermatogenic cells in ureaplasma urealyticum (UU) infected rats and its mechanism were studied. Methods: UU infection in vivo was modeled, and spermatogenic cells of rats were extracted in the primary generation. Serum containing Zhibai Dihuang Decoction (low, medium and high dosage groups) was used as the experimental application factor, while blank group, doxycycline group and model group were set up. After giving the corresponding drug intervention, the test was car...
