Causes and treatment of unsuccessful attempts of conceiving, factors of reproductive health

My husband and I are two years together and almost a year married, and getting pregnant can't.... The reasons tell us a lot. Although both healthy, every time I'm at the gynecologist, and the husband from the first marriage three children. I'm so worried.... Tell me something.... Thanks in advance.

Response: "Hello! There are more than a dozen both male and female factors of infertility. Husband needs to do the spermogram MAR-test and to go on reception to the services, you to see a gynecologist. Also, do not ignore the psychological and physical factors, too strong desire to have children, or when excessive exercise women are often at full reproductive health can't be pregnant. I wish you health"
