A year without contraception and no pregnancy. What should I do?

Women within a year did not do contraceptive measures, but also did not pregnant, this is likely because of abnormal phenomena in some parts of the body caused by, such as tubal blockage, cervical inflammation and other lesions caused by infertility. At this time need to go to the hospital for examination, if it is tubal blockage, can do tubal dredging surgery treatment. In addition, do not rule out because of abnormal sperm quality caused by men, for severe weak sperm, no sperm male, can be IVF.
