This study summarized the sex hormone test data of the included population, and the results showed that the secretion levels of prolactin (p=0.728), follicle-stimulating hormone (p=0.062), luteinizing hormone (p= 0.294), progesterone (p=0.821), estrogen (p=0.686) and testosterone (p=0.056) were not significantly different among the control group, mild to moderate OSA group, and severe OSA group. Here, PRL is linked to obstructive sleep apnea syndrome.
