Fertility Ultrasound: What to Expect During Your First Scan

Why Is a Fertility Ultrasound Performed?

A fertility ultrasound is usually performed to:

• Monitor ovulation or the development of follicles (the sacs where eggs mature in the ovaries).
• Examine the structure and health of the uterus and ovaries.
• Detect abnormalities such as ovarian cysts, fibroids, polyps, or scar tissue.
• Check the thickness of the endometrial lining, which plays a key role in implantation.
• Diagnose conditions like polycystic ovary syndrome (PCOS) or endometriosis, both of which can affect fertility.
• Monitor treatment progress during assisted reproductive technologies (ART), such as in vitro fertilization (IVF).

Preparation for Your First Fertility Scan

Before your first fertility ultrasound, your healthcare provider will give you specific instructions, which may vary depending on whether you’re undergoing a transabdominal or transvaginal ultrasound.

1. Hydration (for Transabdominal Ultrasound): If your ultrasound will be done abdominally, you’ll likely be asked to drink plenty of water beforehand. A full bladder helps provide clearer images of the pelvic organs by pushing the intestines out of the way.

2. No Special Preparation (for Transvaginal Ultrasound): For a transvaginal ultrasound, you will not need to have a full bladder. In fact, you’ll be asked to empty your bladder just before the procedure for better imaging.

3. Comfortable Clothing: Wear comfortable, loose clothing as you may need to change into a hospital gown for easier access during the scan.

What to Expect During Your First Fertility Scan

The fertility ultrasound procedure is quick and relatively painless. There are two main types of ultrasound that might be used during your first scan: transabdominal and transvaginal. Your doctor will determine which type is best suited for your situation.

Transabdominal Ultrasound

• Procedure: You will lie down on an examination table, and a clear gel will be applied to your lower abdomen. This gel helps the ultrasound transducer (a handheld device) make better contact with your skin. The sonographer will then move the transducer over your abdomen to capture images of your reproductive organs.
• What It Detects: This type of ultrasound is useful for checking the overall structure of the uterus, ovaries, and other pelvic organs.

Transvaginal Ultrasound

• Procedure: For a transvaginal ultrasound, you’ll lie on the table with your knees bent and legs positioned similar to a gynecological exam. A small, lubricated ultrasound probe (about the size of a tampon) will be inserted into the vagina to get closer images of the reproductive organs.
• What It Detects: This method provides more detailed images and is often preferred for assessing ovarian follicles, detecting uterine abnormalities, and checking the endometrial lining.
• Comfort: While it may feel slightly uncomfortable, it should not be painful. If you experience any discomfort, let the sonographer know.

Both types of ultrasounds take about 15 to 30 minutes to complete. The transvaginal ultrasound generally provides clearer and more detailed images, making it the preferred choice for many fertility evaluations.

What Happens After the Scan?

After your ultrasound, the images will be analyzed by a radiologist or your fertility specialist. Based on the findings, your doctor will discuss the results with you, which may include:

• Uterine Health: Whether the uterus appears healthy or shows signs of fibroids, polyps, or other conditions that could impact fertility.
• Ovarian Function: The size and condition of your ovaries, as well as the presence of ovarian follicles (which indicate ovulation).
• Endometrial Lining: The thickness and appearance of the lining of the uterus, which is important for implantation of an embryo.

Depending on the results, your doctor may suggest further testing, recommend treatment options, or continue monitoring your fertility health. If you’re undergoing fertility treatment, such as IVF, the scan may be repeated to track progress.

Common Findings and What They Mean

Here are some common findings from a fertility ultrasound and what they might indicate:

• Ovarian Cysts: These fluid-filled sacs are common and usually harmless, but some types (like those associated with PCOS or endometriosis) may require treatment.
• Fibroids or Polyps: These growths in the uterus can affect fertility and may need to be removed, especially if they interfere with implantation.
• Endometrial Thickness: A healthy endometrial lining (typically between 7-14 mm during the implantation phase) is essential for a successful pregnancy. An abnormally thin or thick lining may require further investigation.
• Antral Follicle Count (AFC): This is an estimate of the number of follicles in the ovaries. A high AFC may indicate PCOS, while a low count may suggest reduced ovarian reserve.

Next Steps After Your First Fertility Ultrasound

Once your doctor reviews the results of your ultrasound, they will recommend the next steps in your fertility journey. This might include:

• Lifestyle Adjustments: Recommendations for diet, exercise, and stress management to boost fertility naturally.
• Medications: Fertility drugs may be prescribed to stimulate ovulation or regulate your menstrual cycle.
• Further Diagnostic Tests: If any issues are detected, additional tests (such as blood tests or hysteroscopy) may be needed.
• Fertility Treatments: Depending on the findings, your doctor may discuss options like intrauterine insemination (IUI) or in vitro fertilization (IVF).
