I am sorry to hear that you are having trouble with this. A couple who is having regular sexual intercourse should most of the time be able to conceive within 12 months of starting to try (only 6 months if the female partner is over 35 years of age). If you have not been trying this long yet, then you would not yet meet a definition of infertility and probably should just keep trying!
However, if you have been trying for this long and still have not had suggest, then I would strongly suggest going to see a doctor
about the issue. Issues of male infertility are often managed by either a primary care doctor
or a urologist
, whereas issues of female infertility are often managed by an OB GYN doctor. However, probably the best solution is to make an appointment together at a fertility center, which will be equipped to evaluate you as a couple for both male and female causes of infertility.
From the standpoint of looking for male infertility, the first step will be to perform a semen analysis, which can help determine whether your sperm function and number is normal.
