Female orgasm

My husband and I are newly weds and are officially TTC... Exciting and overwhelming.  I've been reading up on female orgasm and the importance of it.  I understand that we are still perfectly capable of getting pregnant without me orgamsming but I also read material that says it improves our chances if I orgasm.  My question is this... What is the effect on our pregnancy chances if I orgasm during foreplay but not during sex?  Anyone have any insight on this topic?  It would be greatly appreciated.  Thanks in advance and baby dust to all! :-)
