Re: Question about herbs....
OK this is kind of personal, but this is a personal subject so I don't think you will mind my asking. What kind of underwear does he wear. I have heard that tighty whites can keep the "boys" as we call them too close to the body and too warm which can lower sperm count. So he may consider switching to boxers.
As for herbs that help I don't know. Good luck mamma. I know how hard it is when it takes along time to conceive. It took us about 3 yrs to have our 1st.
