Infertility Scans

Ultrasound used for monitoring of ovarian follicle development can provide information about the number and size of developing follicles, the reaction of the uterine lining (Endometrium) to follicle growth, and when to schedule artificial or intrauterine insemination just before you ovulate.

Trans-vaginal ultrasound is better than trans-abdominal ultrasound for monitoring follicle growth, counting the number of follicles, and evaluating the thickness and pattern of growth of the uterine lining. This scan is performed in conjunction with fertility treatment of your doctor.

For a trans-abdominal scan (TAS), the bladder must be full. This provides an “acoustic” window which is created by having a full bladder. This will allow the doctor to improve visualization of the pelvic structures.

In contrast, a full bladder may hinder the imaging when a trans-vaginal scan (TVS) is used. Therefore, a full bladder is unnecessary in this situation.

Results are immediate and a written report will be given to you. Findings of infertility scans include:

a) Normal
The uterus, fallopian tubes, and ovaries are of normal size and shape with no visible growths or scar tissue or injury site (abnormal attachments to the wall of the abdomen). Follicle number and development appear normal.

b) Abnormal
Problems may include:

Abnormally thick or deformed uterine lining.
Structural defects or enlarged uterus.
Growths within the organs, such as uterine fibroids or ovarian cysts.
Abnormalities of the fallopian tubes, such as hydrosalpinx.
Few visible egg follicles in the ovaries.
