Q: Who are the candidates for vasectomy
reversals?
A: With few exceptions, nearly all vasectomised
men are candidates for microscopic reversal procedures, either
a vas-vas (vasovasostomy, VV) or a vas-epididymis (epididymovasostomy,
EV) connection may be performed. Couples with significant female
fertility issues such as fallopian tube blockage or inadequate
egg reserve should consider in vitro fertilization (IVF) since
the restoration of normal sperm count may not overcome the co-existing
female factor.
Q: What are the factors which determine
pregnancy rate following vasectomy reversal?
A: Four major factors are considered in advising
individuals regarding the pregnancy rate following vasectomy reversal:
1. Obstructive interval or number
of years since vasectomy: as reported by the most authoritative
study based on the results of 1469 men (VasoVasostomy Study Group,
1991), the pregnancy rates are 76% for reversal performed within
3 years of vasectomy, 53% for 3 to 8 years, 44% for 9 to 14 years
and 30% for 15 years or more.
2. Age of the female partner: for those couple
with the female partners 30 years or younger, this is not likely
to be a issue. In a study of 115 couples (Fuch, 2001), the pregnancy
rates were 49% with the female age at 31-35, 45% at age 36-40
and 20% at age 41-45. Delivery rates were proportionally lower
in the older group as one would expect.
Since the success rate is inverse proportional to the passage
of time on both partners’ part, the consensus is to proceed
with vasectomy reversal sooner rather than later if the decision
has been made.
3. The use of an operating microscope: the disuse
of an operating microscope in the performance of vasectomy reversal
simply cannot be supported by the literature. The magnification
required to achieve precise suture placement and accurate alignment
cannot be provided by visual aids other than an operating microscope
with sufficient magnifying power.
4. The surgeon: carefully choosing your physician
simply makes sense; whereas some physicians prefer to emphasize
the volume of their practice, my recommendation is to consider
fellowship trained male infertility specialists who are well versed
in all aspects of micro-surgery and fertility related issues.

Q: How involved is the surgery and what’s
the recovery like?
A: For routine reversal or VV, two one-inch incisions
are made high in the scrotum. The amount of dissection is limited
and you can almost equate the reversal to a “super-sized”
vasectomy. The operative time is 2 to 3 hours. For more complicated
reversal or EV, the incisions are longer in order to deliver the
testes onto the operative field. A fair amount of tissue swelling
is expected post-op. The operative time is 3 to 5 hours since
epididymal exploration may be time consuming.
Recovery varies according to the procedure, routine VV is well
tolerated with minimal narcotic requirement and one may return
to a desk job in 3-5 days. EV is a bit more taxing, one should
be prepared to rest for 7 days or more.
Q: What is sperm aspiration?
A: Sperm aspiration in conjunction with in vitro
fertilization and sperm injection, IVF/ICSI, is an invaluable
tool in the management of the infertile couples. Sperm aspiration
is done under local anesthesia with a butterfly needle to obtain
viable sperm and is inexpensive; however, IVF/ICSI is not. Aspirated
sperm are few in number and immature in function, fertilization
requires these sperm be individually injected into each egg in
the laboratory. Pregnancy is then established following successful
fertilization and embryo transfer to the uterus. Direct insemination
is not possible with these sperm and has no role in the management
of the vasectomised men prior to reversal.
Q: Reversal or IVF and what’s
the bottom line?
A: Academic argument for either approach notwithstanding,
one needs to compare the direct cost for each approach. To a significant
degree, the medical discipline being consulted, whether it is
the urologist performing the reversal or the reproductive endocrinologist
overseeing the IVF will influence the couple’s decision.
On average, an IVF attempt with sperm aspiration costs $12,000-15,000
with a pregnancy rate of 25-50%. In contrast, a reversal costs
$6,000-8,000 with a pregnancy rate at least that of an IVF.
Numerous cost-effectiveness studies have been performed
to examine the difference between reversal and IVF. The average
out of pocket cost per delivery following vasectomy reversal is
$15,000 to $31,000 factoring into various prognostic factors and
the procedure performed (VV or EV). In contrast, out of pocket
cost per delivery for IVF, at a very reasonable 35% delivery rate
per cycle, is at least $35,000; this figure does not include the
third party obstetric and perinatal expenses associated with multiple
gestations. A Cornell study (Schlegel, 1997) placed the overall
cost per delivery at $25,475 for reversal vs. $72,521 for IVF.
It is fair to state that vasectomy reversal is at least as effective,
if not more than IVF in most couples at half the cost.
One may argue that IVF obviates the need of a surgical
procedure with the attendant risks. The fact is IVF is an intense
and time-consuming process lasting weeks with repeated office
visits and in-home shot administrations, it then culminates with
egg retrieval under anesthesia and subsequent embryo transfer.
In contrast, vasectomy reversal is straightforward with minimal
morbidity and short recovery; furthermore, since patients are
young and healthy, it has extremely low incidence of complications.
In most couples, the decision is easy; typically, the man had
a vasectomy 6 or 7 years ago and is now remarried to a lady in
her late 20s or early 30s with no fertility problem. Vasectomy
reversal makes sense. On the other hand, if the vasectomy was
performed 20 plus years ago and the wife is only 25 in whom IVF
may achieve a 50% birth rate, then it is perfectly reasonable
to consider IVF if one is willing to accept the higher cost.
Q: Nevertheless, we are really interested
in IVF/ICSI and are considering several IVF centers, where can
we find out more about IVF and these centers?
A: By law, assisted reproductive outcome nationwide
is tallied and reported each year. The annual report typically
takes 2-3 year to comprise. Furthermore, each IVF center’s
result is also available as part of this comprehensive report.

Q: Will vasectomy reversal work considering
my wife is 38 years old?
A: Provided that no major obstacle exists in the
female, vasectomy reversal continues to be the preferred approach.
Fuch et al in 2001 reviewed the results in 115 men who underwent
reversal 15 years or more after vasectomy and reported the pregnancy
and delivery rate based on the partners’ age. The results
are as followed (female age: pregnancy & delivery rate): <25:
57-57%, 26-30: 58-46%, 31-35: 49-49%, 36-40: 45-32%, 41-45: 20-13%
and >45: 0-0%.
Kolettis in 2003 noted a pregnancy rate of 34% in
38 couples with female age 35 or older (mean age 37) after reversal.
One should note that only 8% (1 in 13) of females older than 40
gave birth. The corresponding delivery rate for IVF in women age
41 to 42 is comparable at 10% (1999 SARS data).
In another study by Deck in 2000, 23 couples with
older female partners (mean 39, range 38-48), vasectomy reversal
achieved a pregnancy rate of 22% and delivery rate of 17% with
an average cost of $ 28,530 per birth. Even at an optimistic delivery
rate of 20% with IVF in these older women, the cost per birth
easily doubles that of reversal.
I believe it is reasonable to suggest 30 to 40%
pregnancy rate in couple with a female partner in her late 30s
following reversal. My approach is this group is individually
based. For example, if the vasectomy was within 10 years with
a partner of proven fertility, reversal is favored; if the vasectomy
was 15 years or more in whom EV will be needed which may be associated
with delayed sperm appearance of up to one year post-op, IVF may
be more expedient to take advantage of female’s “window
of opportunity” prior to her 40th birthday.
Q: Is it worthwhile to even consider
a re-do? Does it ever work?
A: Repeat vasectomy reversal should be considered
not only in those who demonstrated zero sperm count post op but
also in those with low sperm count and low motility due to partial
blockage of the system. The success rate is lower when compared
with “virgin” reversal but is still very reasonable
with 75% patency rate and 43% pregnancy rate (VVSG, 1991).
It is difficult to convince one to undergo yet another
attempt at reversal but let’s examine the alternative: Donovan
in 1998 reported in 18 men who undergone repeat reversal 2.3 years
following the initial attempt, cost per delivery was $14,892 for
repeat reversal vs. $35,570 for IVF; again, a significant difference.
The caveat is that up to three-quarters of the re-dos
require EV on at least one side (Hernandez, 1999), a procedure
requiring micro-surgical expertise. Choose your physician carefully
for your re-do, or for that matter, your “virgin”
reversal.
Q: My wife’s gynecologist does
not think vasectomy reversal works well, especially if it is 10
years out, is that true?
A: The wife’s gynecologist is often the first
point of contact when reversal is being contemplated; while most
of our gynecology colleagues are well informed, some are not.
It is not unusual to see couples approaching reversal with a “Hail
Mary” mindset thinking it is the minority who are successful
in having the vasectomy reversed. Many others simply bypass the
option of reversal completely and proceed directly with IVF. The
urology community further contributes to this problem by having
unskilled surgeons performing technically inferior procedures
with sub optimal outcome. The data presented should convince you
the answer to this particular question is a resounding “No”,
provided you choose your physician carefully.
Q: I was told “anti-sperm antibody”
invariably develops after vasectomy and will greatly reduce my
chance at a successful reversal, is this true?
Q: IVF bypasses the presence of “anti-sperm antibody”
so I should go with IVF?
A: Most of men develop anti-sperm antibody
after vasectomy by testing their blood or semen; however, only
the antibody that is sperm-bound is of any potential consequence.
Even so, only a few men may have an antibody issue following technically
successful reversal. In most men, it is a non-issue. Having antibody
in the blood or semen does not predict the presence of sperm-bound
antibody and vice versa. In other words, whether or not antibody
is detected in blood or semen prior to reversal has no prognostic
value and does not affect the management of the individual patient.
Interestingly enough, anti-sperm antibody seems to get much more
attention than it deserves from the gynecologists than those of
us who deal with men directly.
IVF does bypass cases of proven sperm-directed anti-sperm antibody
infertility. As stated earlier, such cases are rare. It is now
apparent that partial obstruction following reversal contributes
to the formation of antibody. Repeat reversal eliminates the formation
of antibody and normalize sperm count. My contention is that we
should concentrate on performing technically sound reversal rather
than worrying about the
antibody.
Q: Will my insurance pay for this procedure?
If not, can you tell them that the reason for reversal is because
of chronic pain to justify coverage?
A: Insurance company rarely pays for vasectomy reversal
and I cannot recall ever being reimbursed by insurance carrier
for this procedure. As a contracted provider with the insurance
company, we are obligated to submit claims truthfully with no
exception. We will not engage in any effort to secure insurance
reimbursement by using alternative diagnosis for the performance
of vasectomy reversal.
