Q & A: "what the possibility of a reversal vasectomy"

Q. I am interested in a man who has had a vasectomy. It is
too early to discuss the children thing, but I am wondering what
the possibility of a reversal is. He is 44 and in good health. He
had the operation between 10 and 12 years ago.

A. Once several years have past since a vasectomy, the
chances of being able to conceive by surgically
re-connecting the tube that carries the sperm from the testicles
is minimal. From a surgical point of view it is technically
feasible, but after the duct has been blocked for so long, the
testicles simply stop producing sperm in sufficient numbers to be
able to conceive.

However, in the past couple of years, progress has been made with
a procedure called intracytoplasmic sperm injection ("ICSI") done
in some fertility clinics. In this procedure, sperm can be
aspirated by needle, or by obtaining a piece of sperm-producing
tissue, and in the laboratory, one sperm is injected into one egg
which is then implanted in the mother. This technique, while
expensive, could be considered. Keep in mind that it is no where
near 100 percent successful, but it can be repeated if necessary.
