For hubby, the biggest thing I've ever been told is watch the soft drinks, particularly diet ones. The artificial sweetener is actually a sperm killer! So if he MUST keep drinking soft drinks, the full sugar ones are actually more healthy. Apart from that, Menevit will do wonders for him, I think its a once a day thing, so he can keep it at work if he doesn't want it lying around. And nice loose undies

For you, it might be an idea to see a naturopath/iridologist/acupuncturist. I've been amazed at the help they've given me, both with weight loss and with fertility. Not cheap, but if you've got private health cover it should help
