Major structures and hormones involved in the initiation of pregnancy. Also seen, at right, is the development of an egg cell (ovum) from follicle to embryo.
Hysterosalpingography is a radiological examination used to evaluate the patency, or openness, of the fallopian tubes in cases of infertility.12
During the procedure, a contrast medium (dye) is injected through the cervix into the uterus, from where it flows into the fallopian tubes. X-rays are then used to monitor the movement of this dye. If the fallopian tubes are open, the dye will pass through them and spill into the abdominal cavity, which serves as a clear indication of tubal patency. If the dye does not pass through, it may indicate an obstruction or scarring within the tubes.12
