A diet rich in fat reduces the quality and quantity of sperm.
Men who eat a diet high in fat have
significantly less sperm production than men with a
lower fat diet.
The results of a clinical study, published in the
magazine Human Reproduction, show that the count and concentration of
sperm is approximately 40% lower in men whose diet contains
37% or more of calories as fat than men with a lower intake
of fats.
A higher intake of omega-3 fatty acids was associated with
better sperm morphology, as well as acid intake
omega-6 fatty acids, but to a lesser degree.
Ninety-nine men with a mean age of 36 years were studied, of which
of which 71% were overweight (BMI 25 to 29.9) and obesity (BMI ≥ 30), and two
thirds had never smoked.
The authors found that 41 had normal semen parameters,
while 12 had low sperm count (<20 million / ml), 52 had a
motility <50%, and 32 had abnormal sperm morphology.A preliminary analysis showed that total fat intake,
saturated fat and monounsaturated fat showed a negative association with
sperm concentration.
Specifically, the analysis showed that a 5% increase in
dietary fat intake is associated with an 18% decrease in
sperm count.
