Sperm and egg health are vitally important, as both mother and father contribute 50% of the DNA to a growing embryo. Therefore the health of both mother and father prior to conception is equally important.
Men are continually making new sperm, which take about 65 days to be produced in the testes. Sperm have limited antioxidant protective mechanisms and are easily damaged, so the health and lifestyle choices of the male during this time can have a massive impact on the health of his sperm.
Women on the other hand are born with all of their eggs already lying dormant in their ovaries. Each month, in fertile women, some of these eggs begin to “ripen” and ultimately one egg (generally the healthiest) is ovulated. Dormant eggs are relatively protected due to their inactive state, however in the four days prior to ovulation cellular activity increases making the egg more susceptible to damage.
No one organ system in the human body functions alone, it is all interconnected, so to pass on healthy genetics, you too must be in good health.
