I remember reading a fertility magazine and it explained how right now it is unexplained but eventually you may find out the results. For me I have zona pellicida or thickening of the cell membrane with requires IVF and AH in order for the cell to adhere to the uterus. I think in the beginning I was driven by this desire to find out what was wrong. I'm sorry you have to venture on this path but you will meet some amazing women along the way. Advice... 1- start with a good Fertility specialist (RE- Reproductive endocrinologist in the U.S) open on the weekends. Make sure you like them and feel comfortable. 2 - read a ton of books 3 - be careful of gimmicks 4 - use caution with "natural cures"
