Intracytoplasmic Sperm Injection

IVF babyICSI (Intracytoplasmic sperm injection) is a safe, effective egg fertilization technique used to treat moderate to severe male factor infertility.

What is ICSI?

ICSI (pronounced Ick-see) is a technique where a single sperm is injected into a mature egg for the purpose of fertilization. In traditional IVF, the sperm are mixed with an oocyte (egg) in a laboratory setting and placed in an incubator allowing insemination to take place. ICSI can increase the rate of fertilization by injecting the sperm directly into the center of the egg.

The fertilized egg is monitored daily and placed in the uterus at the appropriate time, usually within two to five days.

When is ICSI Used?

Intracytoplasmic sperm injection is used in moderate to severe male factor infertility. Indications include:

  • Low or no sperm count
  • Severe teratospermia – a condition associated with abnormal sperm cells
  • Reproductive tract blockage or vasectomy
  • Inability of the sperm to bind to or penetrate the egg
  • Infertility linked to antisperm antibodies
  • Zero percent fertilization rate in standard IVF

Since fertilization problems are common in patients with severe male factor infertility, your fertility specialists may advise skipping traditional IVF and proceeding straight to ICSI.

ICSI Facts

Fertilization occurs in 50 to 80 percent of ICSI procedures but not all fertilized eggs result in a live birth. The live birth rate for ICSI cycles is approximately 50 percent. ICSI is performed by a highly specialized embryologist in an IVF lab. ICSI makes it possible for men with little or no sperm to father genetically related children. DFW Fertility Associates are highly skilled in the ICSI procedure and see patients from Southlake, Keller, Grapevine, Colleyville, Denton and the surrounding areas.
