Lack of historical, directly h o data. IntroductionIn the 1990s, a meta-analysis by Carlsen et al,1 showing a decline in human semen quality, h o a heated scientific debate.

Semen samplesSemen samples were produced by masturbation. Physical examinationA physical examination of each participant was performed on the day of delivery of his semen sample. A p value of ResultsFigure h o shows sperm concentrations, total sperm counts and percentages of morphologically normal spermatozoa for each year of examination. DiscussionIn this large, prospective and well-controlled study of semen quality of annual cohorts of young men from the general population, statistically significant increases in sperm concentration and total sperm counts over the past 15 years were detected.

I regret, that I can not participate in discussion now. I do not own the necessary information. But this theme me very much interests.
