There are many types of examinations for infertility. If the examination is for male infertility, such as a semen analysis, it is recommended not to have sexual intercourse three days prior to the test. For females, if the examinations involve blood tests or a gynecological ultrasound, intercourse is permissible. However, if the examination includes a routine vaginal discharge test, it is advised not to have sexual intercourse for at least three days beforehand. More stringent timing is required for examinations like hysteroscopy or a fallopian tube radiography. The principle here is to conduct these tests three to seven days after menstruation has ended, in order to complete the fallopian tube radiography and hysteroscopy effectively.
