Re: Vitamins/Supplements for DH when TTC

We conceived my first month off the pill, failing miserably with "pull out" birth contorl.

I thought for sure we'd have no chance to conceive since he likes his tighty whities a little too tighty! I was really convinced his factory wasn't going to produce, until we started to wean him off his favorite undies.

DH eats a lot of red meat , doesn't exercise, but isn't obese, has a sweet tooth, and considers any green food to be a vile poison.
He doesn't eat a lot of veggies or fruits overall. He eats a lot of hard cheeses, like swiss. And claims that eating liver once a month is as good as taking a multivitamin every day. He goes to his mom's for the liver, I can't stand cooking it.
