Standardised inclusion and investigation procedures. Lack of historical, directly comparable data. IntroductionIn the 1990s, a meta-analysis by Carlsen et al,1 showing a decline in human semen quality, initiated a heated scientific debate.

DiscussionIn this large, prospective and well-controlled study of semen quality of annual cohorts of journal placenta men from the general population, statistically significant increases in sperm concentration and total journal placenta counts over the past 15 years were detected.
