Male fertility plays an important role in pregnancy, yet many people believe infertility is only related to women. In reality, male fertility problems contribute to nearly half of all infertility cases. One of the most common and preventable reasons for poor sperm health is an unhealthy diet.
What a man eats every day directly affects his sperm count, movement, shape, and DNA quality. Certain foods can quietly reduce fertility without causing any visible symptoms. This blog highlights foods that are detrimental to male fertility, explains why they should be avoided, and helps men make better decisions for improved reproductive health.
Even teenagers may comprehend how food affects fertility because this information is stated in plain language.
Diet is the body’s fuel. Unhealthy eating can harm sperm health in the same way that poor fuel might harm a car.
Sperm generation requires nutrients including zinc, selenium, antioxidants, good fats, and vitamins. Sperm quality gradually decreases when a diet high in processed foods, sugar, alcohol, and junk food is consumed.
For this reason, when attempting to conceive, doctors highly advise avoiding specific meals.
