When it comes to child conception, men who are unable to produce sperm
have an alternate option: sperm retrieval. To ensure successful impregnation,
the methods of sperm retrieval are usually accompanied with in vitro fertilization
(IVF) and intracytoplasmic sperm injection (ICSI).
Sperm retrieval can be achieved with any one of the following procedures provided by visiting
Dr. Green in Sarasota:
Testicular sperm extraction (TESE)
This male infertility option involves an incision of the testes, under
anesthesia, so that sperm can be extracted for an IVF with ICSI.
Testicular sperm aspiration (TESA)
This procedure is alternately known as a
testicular fine needle aspiration (TFNA) ; it involves a needle and syringe, which are used to extract sperm straight
from the testis without a standard incision of the scrotum.
Percutaneous epididymal sperm aspiration (PESA)
This infertility procedure involves withdrawing fluid from the epididymis
with a needle and syringe. Despite its lower success rate, the method
is an easy, low-cost option for the more challenged candidates, such as
vasectomized men who also happen to have azoospermia (low sperm counts).
Microsurgical epididymal sperm aspiration (MESA)
Another option for men with obstructive azoospermia, this involves the
extraction of fluid—through aspiration or incision—from the
epididymal tubules with a syringe and microscope.
Microsurgical testicular sperm extraction (Micro-TESE)
Strictly for candidates without obstructive azoospermia, this method studies
and compares normal and abnormal areas of sperm activity in the testis,
which are opened at the outer layer under a microscope.
