i was just reading a story in o womans mag and the woman had been trying for ages to get pg and had suffered a few misscarrages and started using viagra and was pg in a month and has recently given birth to twins, the doctor said that vigra prob did help but also said you had to be very careful as there was side affects, just thought you ttc ladies might find it interesting but all i can say is please look into it well, i did find this link if it helps any.
