So my cervical mucus is hostile and is destroying the sperm. It's so bad, all sperm was destroyed within six hours of sex. My husband is now nicknaming me "The Enviscerator"

We're still deciding on a course of treatment but I'd like to explore my natural options first if possible (for various reasons- I am a regular blood donar and don't want to be deferred indefinitely while we undergo treatment, the cost of the treatment is just ridiculous, I prefer a natural route where possible).

I've read Evening Primrose Oil is really good for a nice uterine environment, does anyone else have other tips?

Edit - yes this was determined and diagnosed by a doctor. He wants to try some other things first before settling for an actual treatment.
