Association between generalized anxiety symptoms and semen quality in infertile men: A multicentre study in North...

This study was conducted to investigate the generalized anxiety levels and its association with semen quality in infertile men. We recruited male patients who visited the infertility outpatient departments of three teaching hospitals in North China and evaluated their generalized anxiety symptoms using the self-administered 7-item generalized anxiety disorder (GAD-7) scale. Seminal analysis was performed as per WHO guidelines. A total of 378 infertile men (average age: 31.43 ± 5.85 years) were classified into the normal group (n = 174, 46%) and the anxiety group (n = 204, 54%) according to their GAD-7 scale score. The proportion of patients with hyperlipidaemia in the normal group was significantly higher than that in the anxiety group (14.9% vs. 5.9%, p = 0.004). The other demographic characteristics were not statistically different between both groups. Patients with abnormal GAD-7 scale scores had a significantly lower sperm count (202.48 vs. 166.80 million per ejaculate, p = 0.023), sperm concentration (54.75 vs. 46.54 million/ml, p = 0.033), and progressive motility (40.25 vs. 37.16, p = 0.020) than those with normal GAD-7 scale scores. Multivariate linear regression models revealed that anxiety was significantly negatively associated with sperm concentration (percent change = -9.79, 95%CI: -12.38 to -7.12, p < 0.001), total sperm count (percent change = -13.07, 95%CI: -16.05 to -9.84, p < 0.001), progressive motility (β = -1.41, 95%CI: -1.86 to -0.96, p < 0.001), total sperm motility (β = -1.73, 95%CI: -2.38 to -1.08, p < 0.001), and normal sperm morphology (β = -0.16, 95%CI: -0.28 to -0.04, p = 0.009), respectively. Taken together, generalized anxiety disorder could significantly influence the clinical semen quality in infertile men in North China, and psychological stress management might be helpful.
