Good question! Typically you will have symptoms and signs, or blood hormone tests that accompany your fertility status. The formulas are designed to address these issues. In the case of adjusting your AMH/FSH hormone levels, taking another blood test after finishing your three months of treatment is important. Using post-treatment blood tests has a two-fold effect – you know scientifically what results have been achieved, and, you know whether you need to continue using the formulas to improve results, or that in fact you are fixed. Having a CT scan to see howe many eggs are growing in your ovaries, is another way to test the results when trying to improve AMH and follicular growth. For men, a follow-up sperm test after three months of treatment is also necessary to confirm results and determine whether to continue treatment or not.  If you are using the formulas to create pregnancy, restore the menstrual cycle or resolve endometriosis, you will know when they have worked, as the results will be obvious. If you are working to restore an absent or irregular menstrual cycle then once you have had two regular menstrual cycles 26 – 30 days apart, feel confident that the treatment has worked and move onto the next phase of treatment if necessary.
