Effects of work and life stress on semen quality

Abstract

Objective To evaluate associations between work-related stress, stressful life events, and perceived stress and semen quality. Design Cross-sectional analysis. Setting Northern California. Patient(s) 193 men from the Child Health and Development Studies evaluated between 2005–2008. Intervention(s) None. Main Outcome Measure(s) Measures of stress including job strain, perceived stress, and stressful life events; outcome measures of sperm concentration, percentage of motile sperm, and percentage of morphologically normal sperm. Result(s) We found an inverse association between perceived stress score and sperm concentration (estimated coefficient b = –0.09 × 103/mL; 95% confidence interval [CI] = –0.18, –0.01), motility (b = –0.39; 95% CI = –0.79, 0.01), and morphology (b = –0.14; 95% CI, –0.25, –0.04) in covariate-adjusted linear regression analyses. Men who experienced two or more stressful life events in the past year compared with no stressful events had a lower percentage of motile sperm (b= –8.22; 95% CI, –14.31, –2.13) and a lower percentage of morphologically normal sperm (b = –1.66; 95% CI, –3.35, 0.03) but a similar sperm concentration. Job strain was not associated with semen parameters. Conclusion(s) In this first study to examine all three domains of stress, perceived stress and stressful life events but not work-related stress were associated with semen quality.

Disparities in self-rated health across generations and through the life course

“…This on-going surveillance facilitated our ability to locate cohort members at midlife (Susser et al, 2011, Cirillo et al, 2011; Terry et al, 2011; Janevic et al, 2014). Efforts to maintain information about the location of cohort families, the rich data on a relatively large subgroup through adolescence, and sufficient variation in race and SES (see online supplement) make the cohort a strong setting for studying the emergence of health disparities.…”

Quality‐of‐life predictors for men undergoing infertility treatment in Japan

“…Infertile men experience infertilityspecific anxiety and socially isolated men are more vulnerable to severe anxiety (Fisher & Hammarberg, 2011). Researchers from the USA identified life stress as a factor in reducing men's fertility; however, job strain had no effect on the sperm parameters (Janevic et al, 2014). A study of Danish men found that increased stress reduced all sperm parameters (Nordkap et al, 2016).…”

Physical activity, fatness, educational level and snuff consumption as determinants of semen quality: findings of the ActiART study

“…Although reproductive abnormalities in the male partner are identified in about one-half of these cases, few risk factors for abnormal semen quality have been identified (Juul et al, 1999;Kovac et al, 2013). Emerging evidence suggests that lifestyle factors such as smoking (Ramlau-Hansen et al, 2007;Wegner et al, 2010), diet (Afeiche et al, 2014), physical activity (Hajizadeh Maleki et al, 2013;Vaamonde et al, 2006;Wise et al, 2011), overweight and obesity (Crujeiras and Casanueva, 2014;Sermondade et al, 2013), stress (Janevic et al, 2014), and sexual activity habits among others seem to have a cumulative effect on sperm quality (Wogatzky et al, 2012). Physical activity is an efficient method for preventing weight gain, and has a broad and positive systemic influence, such as reducing the risk for cardiovascular diseases, stroke, type 2-diabetes, cancer and metabolic syndrome (US department of Hyealth and Human Services, 2008), and could therefore be potentially related to sperm quality.…”
