There are various methods for assessing the uterus and each method has its advantages and disadvantages. Each evaluation method is selected depending on the individual needs and requirements
• Tubal Factor: The tubal disorders and the adhesion around the tubes and ovaries can be assessed by specific tests.

• Normal spermogram
• Normal ovulation
• Normal uterine cavity
• Open fallopian tubes
