Your doctor will likely do the following:
Blood tests to check [delete] hormone levels in the woman; thyroid, prolactin, and androgen levels
Complete semen analysis on the male partner
Diagnostic testing (Hysterosalpingogram (HSG) or FemVue (Sono HSG) to evaluate if the woman's fallopian tubes are patent
Endometrial biopsy - evaluates the quality of the uterine lining (if appropriate)
Laparoscopy - out-patient surgery to check for endometriosis or pelvic scarring in the woman
If you have not had these tests done, ask your doctor about them.
