An analysis of effect of diet on semen parameters

Introduction: The importance of diet in determining the quality of human semen has been recognized for quite some time. Mediterranean’ dietary pattern derived by principal component analysis (PCA), which was characterized by high intakes of vegetables, fruits and seafood, was positively associated with total sperm count. With the above background, we conducted a study to know the adherence to Mediterranean diet and its effect on semen parameter.
Materials & methods: This cohort study was conducted in NEIGRIHMS from Jan 2016 to December 2018.  We included 411 male partners aged 20–45 years and without any medical history of systemic diseases, cryptorchidism, varicocele, microorchidism, vasectomy or hormonal treatment in the last six months in the study after adequate counseling. Participants were informed about the importance of intake of Mediterranean diet (Med diet) and to quit smoking. After 6 months to 1 year of following the advice, the participants came to andrology laboratory for semen analysis. The semen parameters, Mediterranean diet score and smoking habits were correlated by using spss software version 22.
Results & Observations: It is seen that individual calculated p-value for coefficients of Progressive motility rate, Non- Progressive motility rate and Morphology are less than 0.05 at 5% level of significance. Also it shows from the table that there may be positive correlation with Mediterranean diet score. 
Conclusion: Greater adherence to this traditional diet was associated with a lower likelihood of having an abnormal semen profile, which suggests that dietary modifications and compliance to the Med diet may help improve semen parameter.
