What is a Hysterosalpingogram (HSG) and How is it Used During an Infertility Evaluation?

Dr. Marika Raff • January 28, 2025

When couples or individuals begin their fertility journey, one of the first and most important steps is a thorough evaluation to identify the underlying causes of infertility. At Caperton Fertility Institute, we use several advanced diagnostic tools to assess reproductive health. One such tool is the hysterosalpingogram (HSG), a specialized test that provides critical information about the health of the uterus and fallopian tubes.

If your fertility care team has recommended an HSG, or if you’re curious about how it fits into the fertility evaluation process, here’s everything you need to know about this procedure and its role in helping you achieve your dream of parenthood.

What is a Hysterosalpingogram (HSG) and How is it Used During an Infertility Evaluation?

When is an HSG Recommended?

An HSG is typically performed as part of the initial fertility evaluation for individuals or couples who are having difficulty conceiving. It’s especially useful if:

  • You’ve been trying to conceive for over 12 months (or 6 months if you’re over 35).
  • You’ve had a history of pelvic infections, endometriosis, or abdominal surgery, which may increase the risk of tubal blockages or adhesions.
  • You’ve experienced recurrent miscarriages.
  • Your care team needs to confirm that your uterus and fallopian tubes are healthy before starting treatments like intrauterine insemination (IUI) or in vitro fertilization (IVF).

What Can an HSG Reveal?

The HSG provides valuable information about two critical components of female fertility:

1. Uterine Abnormalities

The shape and structure of the uterus are essential for successful implantation and pregnancy. An HSG can reveal:

  • Fibroids or Polyps: Growths that may distort the uterine cavity.
  • Congenital Uterine Abnormalities: Conditions like a uterine septum or bicornuate uterus, which can interfere with pregnancy.
  • Scar Tissue (Adhesions): Adhesions inside the uterus (Asherman’s syndrome) that can result from infection or surgery.

2. Fallopian Tube Blockages

Open fallopian tubes are essential for natural conception, as they allow the egg and sperm to meet. An HSG can detect:

  • Blocked Tubes: A blockage in one or both fallopian tubes can prevent fertilization.
  • Hydrosalpinx: A condition in which fluid builds up in the fallopian tubes, potentially impacting fertility and the success of IVF.
  • Tubal Damage: Scarring or irregularities in the tubes caused by infections, endometriosis, or prior surgeries.

Embarking on the embryo transfer phase of your IVF journey is a big step, and understandably, patients often ask what they can expect during this important stage. At Caperton Fertility Institute, we take great care in preparing your body to create the most welcoming environment possible for a developing embryo. Here’s an overview of how we prepare you for a frozen embryo transfer, including the medications we use and why they matter. 1. Estrogen Patches to Build the Uterine Lining The first step in the preparation process involves thickening the endometrial lining of your uterus so it can support an embryo. We use estrogen patches for this purpose. These patches deliver a consistent dose of estrogen through your skin, and you’ll typically wear several patches on your abdomen at a time, changed every other day as instructed. Estrogen helps your uterine lining grow to the ideal thickness for implantation. We monitor this closely with ultrasound to ensure optimal conditions. 2. Adding Intramuscular Progesterone Once your lining has reached the right thickness, we introduce intramuscular progesterone injections. Progesterone transforms the uterine lining into a receptive state, mimicking what happens naturally after ovulation. These injections are given daily and are an essential part of making the uterus ready to accept an embryo. While the thought of intramuscular shots can be intimidating, our team will guide you through every step and offer tips to make the process more comfortable. 3. Timing the Transfer The timing of your embryo transfer is carefully coordinated based on your hormone levels and the day your embryo was frozen. For example, if you're transferring a blastocyst (an embryo that developed for five days), we schedule your transfer five days after starting progesterone. Precision is key, and we tailor the timing to closely replicate the conditions of a natural cycle. 4. Day of the Transfer The transfer itself is a quick, gentle procedure that doesn’t require anesthesia. We use ultrasound guidance to place the embryo in the uterus, and many patients describe it as similar to a Pap smear. Afterward, you’ll rest briefly before going home. Supporting You Through Every Phase Every part of the embryo transfer preparation is designed with care and intention. We want to give you the best possible chance for success, and we’re here to support you emotionally and physically throughout the process. If you have any questions about preparing for your embryo transfer or the medications involved, don’t hesitate to reach out. We’re with you every step of the way.
