Medical Research: What are the main findings of the study?
Prof. Jensen: Our study suggests that even modest habitual alcohol consumption of more than 5 units per week had adverse effects on semen quality although most pronounced effects were seen in men who consumed more than 25 units per week. Alcohol consumption was also linked to changes in testosterone and SHBG levels.
Medical Research: What was most surprising about the results?
Prof. Jensen: That an adverse effect was found even at low habitual alcohol intake.
Medical Research: What should clinicians and patients take away from your report?
Prof. Jensen: Young men should be advised that high habitual alcohol intake may affect not only their general but also their reproductive health
Medical Research: What recommendations do you have for future research as a result of this study?
Prof. Jensen: More studies on possible mechanisms and intervention studies to determine whether semen quality is restored if alcohol intake is reduced
