herbal approaches to motility issues

This is a topic very close to home for my wife and me.
I wonder if you have any thoughts on herbal approaches to motility issues, or egg production?

For motility I have seen astragalus (Astragalus membranaceous) and Fo Ti root (Polygonum multiflorum). Egg quality is a more in depth conversation. Both of the parents have the ability to effect quality with their overall health. Egg quality is enhanced with some of the general reproductive tonics, raspberry leaf, nettle, etc. You asked about egg production though... I wonder if you mean ovulation itself, or the buildup of the follicle?

I was referring to build up of the follicle.

Thank you for the information.
