Surgery can often fix blocked tubes in your reproductive tract or
make connections that never developed because of congenital defects.
Our doctors specialize in delicate treatments to treat obstructive
azoospermia, safely and effectively restoring the flow of your sperm.
Learn more about obstructive azoospermia. If surgical reconstruction
is not possible, or you wish to avoid it, there is often another
option. Our specialists can extract sperm from the:
Epididymis, the adjacent tube where sperm
Vas deferens, the tube that takes the sperm from
We use extracted sperm to attempt pregnancy via in vitro
fertilization (IVF). Learn more about sperm extraction.
Our specialists will take the time to fully discuss the options with
you and help you make a decision. If surgery is possible, there are
two types: microsurgery and endoscopic surgery.
Obstructive azoospermia and microsurgery
Microsurgery is a proven technique with a long history. Our experts
have special fellowship training to perform it, meaning they studied
an additional year to specialize in this treatment. During surgery:
You are put completely to sleep with general anesthesia.
Your doctor makes a small incision on your scrotum.
Using high-powered magnification and special instruments, your
doctor carefully fixes the blockage or restores the missing
connection and closes the incision.
We use microsurgery to repair problems with the epididymis and the
Obstructive azoospermia and endoscopic surgery
Endoscopic surgery is a minimally invasive procedure that uses a
smaller incision. During surgery:
You are put completely to sleep with general anesthesia, with
additional local anesthesia for your comfort.
uses a special scope (very thin, flexible tube) with a camera, light
and magnification into the surgical spot, with the image projected
onto a monitor for guidance.
The scope is delicately
threaded through your urethra — avoiding the need for an incision.
We carefully repair the blockage.
We use endoscopic surgery to repair problems with the ejaculatory
duct, the tube from which the sperm exit into the urethra and mix with
fluid to form semen.
