Infertility is not being able to conceive even after a year of unprotected intercourse. Mainly, there are three types of tests which are required to determine the cause. Firstly, semen analysis of the husband is done to ensure that there is adequate number of sperms being produced. The second test is done to see whether ovulation is happening in the woman or not with the help of an endometrial biopsy or having a simple hormone test. The progesterone test is done one week prior to the next predictable menses.
If both the tests are normal, then the next test is an x-ray. A hysterosalpingogram (HSG) is done to see if the fallopian tubes are open and in order to make sure that the uterine lining is well-matched for embryo attachment. A dye is injected through the cervix into the uterine cavity. This test tells that the sperms are able to get to the fallopian tubes where fertilization takes place and the egg can be captured by the fallopian tube. These three tests are the basis to infertility evaluation.
