There's an exciting new approach in fertility health called Napro Technology (Link) which aims for a much more profound understanding of optimal male/female health, in order to rebuild or strengthen the natural procreative function. I hope you might find this interesting,and helpful.
That stuff must be some new Catholic program; my sister in law gave me the same information. Unfortunately while it may be somewhat helpful to other women it’s useless for what’s wrong with me.
But I really don’t see how take medicine to change the way my body operates - the way God made me personally - ok, but using a condom would not be. Both ways could be seen as a human saying “Thanks anyway God but I know better”.
