I know that one issue that came up was the fact that some women need to go to the toilet straight after BD and can't lay on their back for half an hour. However Drs. say that urination after sex helps to prevent urinary tract infections and that it shouldn't dramatically deacrease the chances of fertilisation.

Also, the female orgasm. Does it help fertilisation? Can it hinder fertilisation if you have them during the TWW (especially if you have a lot of discharge)?

Otherwise, I think most other things have been covered!

Oh, and mobile phones - do they decrease male sperm count if kept in their pockets? Should the male also keep his "package" cooler to increase sperm count? Should he stop drinking so much beer? (hint, hint DH!!! lol)
