In case, the women age is over 35 years, the couple needs to visit the doctor earlier because the fertility testing takes time and according to study, the female fertility starts declining when she is in her 30s.

A doctor can give advice and carry out some preliminary assessments. It is advisable for the couple that they visit the doctor together as she might ask about the couple's sexual habits and accordingly make recommendations. Tests and trials are available; however, testing does not always reveal a specific cause.
