When I work with my fertility clients, I always encourage a 90-day preconception window. Why is this?Egg and sperm don’t develop overnight, and we can greatly influence the quality of both which is such a powerful thing to remember. In a world where so many things are out of our control this can really make a difference.Eggs take ~90 days to mature before ovulation.Sperm take ~64–74 days to develop, plus 10–12 days to finish maturing.This means the 3 months before conception are a powerful window. During this time, both egg and sperm are highly sensitive to nutrition, oxidative stress ( this is an imbalance in our body of unstable molecules that can damage cells and antioxidants which can combat this) and lifestyle habits. Things like diet, toxins, stress, sleep, weight, caffeine, smoking/vaping and alcohol can all affect their quality.Nutrition and lifestyle factors make a difference cumulatively, not instantly, which is why consistency over 3 months is key.You can’t change your genetics, but you can change the environment your eggs and sperm develop in — and that’s where the 90-day window becomes so powerful. ✨
