Infertility: Infertility can be due to female issues or male issues. Also it depends on how often you have intercourse. The best thing for you to do is to see an Infertility specialist but you need to take your male partner with you as he will need to do a semen analysis as well. He has to be willing to go through the workup as 30-40% of the time the problem lies with the male.
