Intracytoplasmic Sperm Injection (ICSI)
An alternative method of achieving egg fertilization is called
Intracytoplasmic Sperm Injection, or ICSI. An extremely sharp glass
needle is used to inject one normal appearing sperm directly into the
center (cytoplasm) of the egg under the guidance of a specially fitted
microscope.
Candidates for ICSI include men with (1)
severely compromised sperm parameters, including low concentration,
motility, morphology, or antisperm antibodies; (2) blockage or absence
of the vas deferens, where sperm is surgically collected by epididymal
aspiration or testicular biopsy for ICSI; (3) those who had low or
failed fertilization on prior IVF attempts; (4) unknown infertility
(causes of couple's infertility remain unknown after completing all
diagnostic testing); (5) certain medication or other medical history.
The
success rate with this technique varies considerably among IVF programs
and is highly dependent upon the skill of the embryologist performing
the procedure. Our excellent results have been documented in an article
published in the medical journal Fertility and Sterility, and the
Centers for Disease Control and Preventions Assisted Reproductive
Technology Annual Report.
