Prenatal vitamins & fertility?

A quick google search didn’t produce a whole lot of concrete information on this so I want to ask you ladies... do prenatal vitamins improve your fertility? What’s your favorite kind? The first kind I tried was Nature Made but shortly after that I started taking One A Day prenatal, the one that comes with the DHA/EPA liquid gels. They’re so big that I can’t swallow them normally so I take them with apple sauce (not crushed, just easier to swallow them being suspended in a thicker substance). I sometimes forget to do this because I’m rushing in the morning so I picked up a bottle of Vitafusion prenatal gummies to keep in my purse for backup.

~I do not double up on prenatals~

Does anyone feel that one kind was better than the other for them? I know they’re good to take when you’re ttc regardless, but I wanna hear from women who really feel like their vitamins did more than lay a nice foundation for their pregnancy, or from anyone with an opinion on the topic really.

~oh, and if anyone has any experience with male pre-pregnancy vitamins, please share. Right now my boyfriend is just taking One a day men’s, but they make a couples pack and I was curious as to what they could possibly put in the couples pack that isn’t already in a regular mens vitamin. They appeared to be the same when I did a quick comparison in the store.
