Every case of infertility is different. No one can tell you an exact time to seek the advice of an expert. There are some guidelines to follow to help decide when the time is right for you. If you've had three or more miscarriages or pelvic infection, you're probably a good candidate for a specialist. Being over 35 years old might cause you a problem with fertility since fertility decreases with age. If you need microsurgery or treatment for endometriosis or tubal damage, seek a specialist. An irregular menstrual cycle, signs of irregular ovulation, or low semen count or motility can be signs that you and your partner might need expertise in the field of infertility. If you've had some basic infertility tests, which come back normal, but still can't conceive after two years, talk to a specialist to discuss your options. The time to seek an expert isn't cut and dry.
