Hysterosalpingography (HSG)

Classical hysterosalpingography (HSG) is an X-ray exam that uses a radiopaque contrast (solution) to determine the patency of the fallopian tubes. This procedure, done under fluoroscopy, uses X-rays and is therefore only carried out in radiology centers or in hospitals.

Hysterosalpingosonography (HSSG)

For many years now, HSG has been largely replaced by hysterosalpingosonography (HSSG), performed by ultrasound. The radiopaque solution is simply replaced by the instillation of saline water. It is this medical imaging technique that we offer at Fertilys. It is as sensitive and specific as HSG in confirming fallopian tube patency.

The benefits of hysterosalpingosonography

Compared to HSG, HSSG also has several significant advantages:

  • It does not expose our patients to X-rays;
  • Since it's a vaginal ultrasound technique, it allows for a more global view of the uterus and ovaries;
  • It offers us the ability to determine indirectly the ovarian reserve (number of eggs) by antral follicle count;
  • It makes it possible to examine the uterine cavity in 3D, as well as to detect several pelvic pathologies which would not necessarily be detected by conventional HSG.
