For many years I was told I would not be able to conceive.  I changed my eating habits and incorporated at least 30 min of exercise per day.  I am a vegan raw foodist  now it works for me. it may now work for you but i have two children 13 and 10.  Gradually i reduced the amount of fats i consume and i began eating more dark leafy greens.  even green smoothies which are 60% fruit and 40 % leafy greens.  I train to run half marathons and lift weights at least 4 days a week. I am 46 years old.
