why wy?

I'm currently researching how osteopathic treatment can help couples conceive and I turned up this link on the optimal diet and lifestyle for conception.

I haven't found a single source that is the definite authority on boosting fertility but going back to first principles, it makes sense to start at the blood, venous and nerve supply to the reproductive organs and pelvic mechanics. If the body and organs are free to move, they will be able to carry out their function. Freeing restrictions around the T10 to TL region seem to have good results, anecdotally.
