Intracytoplasmic Sperm Injection (ICSI) in Las Vegas

When male factor infertility is preventing conception, intracytoplasmic sperm injection — ICSI — is one of the most effective tools available. At The Fertility Center of Las Vegas, our embryologists use ICSI to overcome barriers ranging from very low sperm count to poor sperm quality, giving the fertilization process the most direct support possible.

What is Intracytoplasmic Sperm Injection and how does ICSI work?

Intracytoplasmic sperm injection (ICSI) is a laboratory fertilization technique performed as part of an In Vitro Fertilization (IVF) cycle. In a standard IVF cycle, eggs and sperm are placed together in a culture dish and fertilization happens naturally — a sperm must swim to the egg and penetrate its outer shell on its own. Laboratory fertilization occurs after the steps of ovarian stimulation and egg retrieval. During a traditional IVF cycle without ICSI, an embryologist will combine each egg with sperm in a petri dish. The goal is to allow the sperm to swim to the egg and penetrate its shell to achieve fertilization. However, when the sperm has trouble moving properly or lacks the strength to attach to the egg, the ICSI can be the solution.

With ICSI, our embryologists take a more direct approach. Here’s the process:

1. Sperm selection: the embryologist examines the semen sample under a high-powered microscope and selects a single sperm with the best morphology (shape) and motility (movement) for each egg to be fertilized. We will need as many healthy sperm as there are eggs to be fertilized.
2. Sperm injection: using a very fine needle, the embryologist injects the selected sperm directly into the center of the egg.
3. Embryo development: the fertilized egg is monitored as it develops in our laboratory over the next few days before being frozen or transferring one to the uterus.

ICSI results in fertilization of approximately 50 to 80% of injected eggs. Because all of this happens in our laboratory, the physical experience for you is identical to a standard IVF cycle — no additional procedures or discomfort.

Who can benefit from the ICSI sperm procedure?

ICSI is most commonly used for severe male factor infertility, including:

• Very low sperm count (oligospermia) or no sperm in the ejaculate (azoospermia)
• Poor sperm motility — sperm that cannot swim effectively toward the egg
• Poor sperm morphology — sperm with an abnormal shape that makes natural penetration of the egg difficult
• Obstructive azoospermia: when a blockage prevents sperm from being ejaculated, a testicular biopsy is performed and the retrieved sperm are used for ICSI

ICSI is also recommended in the following situations:

• Unexplained infertility
• Previous IVF failure or recurrent miscarriage
• Preimplantation genetic testing (PGT): ICSI is used to avoid contamination from other sperm when biopsying the embryo
• Use of frozen eggs: the freezing process can harden the outer shell of the egg, making natural sperm penetration more difficult — ICSI bypasses this entirely

Identifying these fertility barriers early on is vital. If the sperm count is too low for an Intrauterine Insemination (IUI), ICSI is the recommended path.

At The Fertility Center of Las Vegas, we also recommend ICSI to any patient who simply wants to improve their chance of experiencing IVF success. Contact us if you’d like to learn more about this fertility treatment and how it can help you become a parent.

Understanding ICSI success rates

Knowing your pregnancy odds with ICSI is a very important part of the process. In general terms, the ICSI technique is a very effective tool to maximize egg fertilization in the laboratory. By injecting the sperm directly inside the egg, we manage to overcome almost any male infertility barrier.

Fertilization is one step in the IVF process. Whether a fertilized egg develops into a transferable embryo depends on other factors too: egg quality, the embryo’s chromosomal health, and the uterine environment. ICSI addresses the fertilization step specifically — and for patients with significant sperm barriers, it makes that step far more reliable.
