A pelvic ultrasound looks at the size and structure of the uterus and both ovaries. It can check the condition and size of the ovaries during treatment for infertility. It can also be used to check a woman's egg supply (ovarian reserve). This is done by counting the number of follicles in both ovaries during a certain phase of the menstrual cycle (antral follicle count).
A hysterosalpingogram is an X-ray test that looks at the inside of the uterus and the fallopian tubes. The pictures can show a blockage of the fallopian tubes that would prevent an egg from reaching the uterus or prevent sperm from moving into a fallopian tube to join (fertilize) an egg. This test may also see problems on the inside of the uterus that might prevent a fertilized egg from attaching (implanting) to it.
Laparoscopy is a procedure to look at a woman's pelvic organs (uterus, fallopian tubes, and ovaries) using a thin, lighted scope that is put through a small cut (incision) in the belly. This procedure is used to find cysts, scar tissue (adhesions), fibroids, and infections that can affect fertility. Laparoscopy can also be used to treat conditions, such as endometriosis. Laparoscopy is usually done with general anesthesia.
