Before the onset of investigation and treatment of infertility we should answer an important question: has the frequency of sexual intercourse been adequate, despite which no pregnancy has occurred?

If the answer is yes and no conception has been achieved in a period of one year, then it is necessary to investigate the causes of subfertility in order to select the suitable treatment.

The philosophy of dealing with subfertility may include:

• a "wait and see" period
• undergoing tests to explore the causes of subfertility in order to select the suitable treatment
• time course of treatment (intrauterine insemination, hysteroscopy-laparoscopy etc)
• direct application of IVF
