Thank you for choosing Healthcaremagic. I suppose DIM is a herbal supplement, there are no studies which have proved this to be effective. About the shrinkage of fibroids it depends on the size and its location. As you are 47years its unlikely you will become pregnant, if you are so concerned go ahead with LEVONORGESTREL
INTRAUTERINE DEVISE. I feel it suits you, and it even decreases the size of the fibroids.
I hope this information has been both informative and helpful for you. In case of any doubt, I will be available for follow-ups. If you like my answers kindly rate it, and write a review as well. Please do not forget to accept it.
Wish you good health.
