Gynography is nothing but, doing the “Radiography of the female genital organs” that uses “air or other gas” that is injected intraperitoneally as a contrast medium. Gynography was first invented by Abner I. Weisman

Gynograph is a new improved gynoroentgenologic apparatus which is used by gynecologists and radiologists in performing hysterosalpingography. Advantages of the gynograph is  when a foreign material is inserted into the uterus,  it is "practically free from complications" such as intravasation of the venous sinuses of the uterus and pulmonary emboli, cysts, pelvic peritonitis, rupture of the fallopian tube, and death. The only side effect is the occasional flaring-up of an old chronic salpingitis.
