Fruit vs Fast Food: What Malaysian Men's Diets Mean for Sperm Health

Researchers looked at men visiting four fertility clinics in Peninsular Malaysia. They gathered information on what the men ate, their education, income and other background details. Sperm quality was taken from medical records and split into normal or abnormal groups.

A food frequency questionnaire helped estimate how often participants consumed different food groups. The analysis used logistic regression, adjusting for household income and education level. Age and body mass index were also checked but showed no link to sperm quality.

Men who ate more fruit tended to have better sperm quality, with an adjusted odds ratio of 0.83. Frequent fast‑food consumption showed the opposite pattern, raising the odds of poorer sperm quality to about 1.55. Other food groups such as vegetables, dairy, meat, caffeine and sugary drinks did not reach statistical significance.

Education level and household income themselves were significantly related to sperm quality. Higher education and higher income were associated with better outcomes. The study suggests that both what men eat and their social circumstances play a role in reproductive health.
