Ejaculatory abstinence and its impacts on within- and between-individual variations in semen parameters of 9,595 Vietnamese men.

ABSTRACT:

Background

Ejaculatory abstinence (EA) is the key to assessing the semen analysis. While its fundamental roles on all sperm and semen parameters have been studied for decades, there are still controversies about whether shortening or lengthening EA would be beneficial. Despite natural variations of human semen, most studies in this field investigate the influence of EA using between-individual approaches that cannot control intra-individual covariates. There is still little evidence on how deviation in EA between two samplings affects variations in semen parameters. This study aimed to revisit the relationship between EA and semen parameters, especially in the within-individual analysis and in terms of two-time EA deviations.
