Erm...eh? It seems I missed two pages of posts 
Madam, we don't know each other so please excuse me if I seem intrusive, but your post is so sad. I am sorry your husband has battled cancer and now you are both battling bureaucracy. You read about this kind of mindless cruelty in the papers and wonder how couples get through it, but through it you must go. May I ask, are finances the reason you are mostly distraught, ie you feel you absolutely cannot fund IVF yourselves? Have you researched the cost of taking your husbands sperm to Europe where the success rates are much, much better than the UK?
I am thinking of Serum in Greece who are the pioneers of some of the more radical IVF treatments we see working today. I know of many success stories coming from couples who transfer their sperm from UK clinics to Serum for half the cost of a UK cycle. I'm just not sure how much fight you and your DH have in you to tackle a hospital over this issue. Can you beg, borrow or steal the funds to go and finance a cycle yourselves?
Soda, how long have you been tracking your cycles? Once you have pinpointed ovulation for a couple of cycles you can stop wasting time having sex too soon in your cycle and save your energy for the real fertile window. Keep talking to your DH and kissing and complimenting and stuff. They need that shit in order to not feel like abused spaff machines.
