One of my friends has been TTC for 3 years with her OH. Shes decided to start taking folic acid tablets, She came off the pill 4 years ago & it has definately worn off now as her body was back to normal within a year. However, her OH drinks a lot & occassionally does drugs. Both know this could be the only problem they cant concieve but he wont go to the doctors about it. Shes been & shes in the clear of any problems. Will folic acid tablets help?
