With female patients, the cause of infertility can be tested through special imaging, blood tests, hormone levels, and other procedures. Special imaging tests can be performed through a hysterosalpingogram (HSG) or sonohysterogram to view the uterine cavity for abnormalities or other issues. Blood tests for ovarian reserve determines the number and quality of eggs in the ovaries, and the ovarian follicle hormones; this is tested by follicle-stimulating hormone (FSH), estradiol, clomiphene citrate challenge test (CCCT), and anti-mullerian hormone (AMH) tests. Other female fertility tests include hysteroscopy, endometrial biopsy, thyroid-stimulating hormone (TSH) test, and prolactin hormone test.
With male patients, fertility is determined by checking sperm quality, production and movement. Semen analysis, postcoital tests, and prolactin hormone tests are used to evaluate the sperm.
