Selenoproteins like glutathione peroxidases (GPx‐1, GPx‐3 and GPx‐4) (Akpinar et al. 2023), selenoprotein P (SELENOP), and selenoprotein S (SELENOS) play a crucial role in sperm development, maturation, protection of ovarian follicles, and regulating oophoritis and placentitis. The gene discussed is SELENOP; the disease is oophoritis.
