Lifestyles of men in barren couples and their relationships to sperm quality

Lifestyle and semen quality: role of modifiable risk factors

“…Some suggested no association [Oldereid et al 1992;Ramlau-Hansen 2008], whereas others found reduced sperm concentration, total sperm count, and motility [Jensen et al 2010;Sobreiro et al 2005;Vine 1996]. In the present study, coffee consumption increased the percentage of motile sperm cells and the percentage of sperm head and neck abnormalities.…”

“…Also studies on caffeine intake and semen quality have shown contradictory results. Some suggested no associations [Oldereid et al 1992;RamlauHansen 2008], whereas others found reduced sperm concentration as well as reduced total sperm count and motility [Jensen et al 2010;Sobreiro et al 2005]. Global System for Mobile Communications (GSM) phone usage in 5 days for 6 hours per day decreased the rapid progressive motility of sperm [Davoudi et al 2002] and duration of mobile phone use was negatively correlated with sperm motility and positively with the proportion of slow progressive motile sperm [Fejes et al 2005a].…”

Use of fluorescence in situ hybridization (FISH) to assess effects of smoking, caffeine, and alcohol on aneuploidy load in sperm of healthy men

“…to advantage in the sperm banking sciences [Haesungcharern and Chulavatnatol, 1973;Aitkin et al, 1983;Barkey ACKNOWLEDGMENTS et al, 1984;Rees et al, 1990;Imoedemhe et al, 1992;Sharma et al, 1996].

Long‐term alcohol exposure prior to conception results in lower fetal body weights

“…Although some studies have found no association between alcohol intake and semen quality (Dunphy et al, 1991;Oldereid et al, 1992;Goverde et al, 1995), Zhu et al (2000) have shown that long-term ethanol increases the number of apoptotic spermatogonia and spermatocytes.…”
