. For patients with
abnormalities on semen analyses, intracytoplasmic
sperm injection (ICSI) is used to assist
fertilization.
In this procedure, an extremely sharp needle is used
to inject a single sperm into the center of the
cytoplasm of each egg under microscopic guidance. This
technique has been used in human IVF since the early
1990s. ICSI has dramatically changed the treatment of
male factor infertility. The fertilization rates with
sperm injection average 70% regardless of the severity
of the male factor. This technique is used for men
with severely depressed sperm parameters, men with
absent or blocked vas deferens, in cases where sperm
is aspirated directly from the epididymas or testicle,
and in cases with history of failed fertilization with
IVF. The pregnancy rates with IVF/ICSI are the
equivalent of those couples without male factor
infertility who have standard IVF.
For patients whose condition requires the surgical
extraction of sperm,
Urologists trained in fertility perform the procedure
of TESA / MESA in our Surgical OT .
