Arab A, et al. - The target of this research was to appraise the tie-up between dietary patterns and semen quality. Enrollees in the lowest adherence reported a markedly lower level of sperm concentration than those who had the highest adherence to the healthy dietary pattern. There was, nevertheless, no prominent connection between eating patterns and other semen quality. It was deduced that a healthy dietary pattern possibly correlated with elevated sperm concentration level. In order to clarify this relationship, additional exploration was necessitated.

Methods

• Data was extracted from the PubMed, Cochrane library, Science direct, Scopus, Google Scholar, and ISI web of science databases, up to August 2016.
• The trials included were observational studies evaluating the correlation between common dietary patterns and sperm quality markers.
• Data were pooled by the generic inverse variance method with random effects and expressed as mean differences with 95% confidence intervals (CIs).
• A scrutiny was performed of the heterogeneity (Cochrane Q-statistic) along with quantification (I2-statistic).
• The study quality was inspected via the Newcastle-Ottawa Scale.

Results

• This study consisted of six eligible studies, involving 8207 subjects.
• It was reported that the pooled mean difference of sperm concentration for the healthy dietary pattern versus unhealthy dietary pattern intake was mean difference: 0.66; 95% CI, 0.305-1.016; p < 0.001.
