HI Mooshie,
I know it's a long time to be trying to conceive but it's not a lot different to other times for you is it?
Folate has been shown to improve dna however it needs to be taken in conjunction with vitB12 and vit B6 I believe. As most women have heard "older " women are encouraged to take higher doses of folate and this will increase the chances of conception. I believe that this is one of those "wives tales" but I think it has some merit to it. Especially since we know that increased folate improves dna and dna is what cells are all about...
Folate rich food in "the old days" was also encouraged when ttc and if a miscarriage was threatened. So folate has a bit of a history in aiding with conception and in keeping pregnancies sticky...

Women who recurrently miscarry are often advised to increase their folate consumption to 5mgs. In Australia until recently the rdi folate supplement for pregnant and breastfeeding Mamas is 5oomcgs. So you can see the extra folate recommended to women such as myself is considerably higher. Folate by food sources cannot be relied upon as folate is easily damaged and destroyed. One of the prominent studies done in Israel on women who recurrently miscarry the women were all given a supplement of 5mgs of folate.

I don't like to recommend what to do as this could be seen to be giving medical advise. However, I do it, granted mainly due to the recurrent miscarriage factor but also due to my age. I also believe it is beneficial for you partner to be on it also. I don't really understand why his dna isn't as important (to some!) in the equation. So my ever suffering hubby pops his pills religiously every night!

Have you considered just having a cd21 blood test to confirm good ovulation? Not that I am thinking anything is amiss especially since it has taken some time to conceive for you in the past... Just a thought...

You are absolutely right. Bring on those gorgeous beautiful healthy eggs of ours to be met by and equally handsome and beautiful sperm!

I hope that helps some....
