Outstanding
Infertility Centers
There are nearly
300 clinics affiliated with the Society for Assisted Reporductive
Technology. How do you choose the best one for you? Start
by collecting recommendations from doctors and others you
trust, then ask probing questions before signing on with a
facility. Also, Assisted Reproductive Technology Success
Rates, a directory of data from centers across the country,
can point you to clinics achieving higher-than-average pregnancy
rates or treating a larger number of couples with particular
problems. Based on the most recent directory figures, these
ten centers stand out:

Maybe you've just gotten married and
have vague plans to start your family in a couple of years. Maybe
you have one child and think you'll have a second with the same
ease. Or maybe you're just beginning to wonder whyafter three
months of trying (or six or eight)you're not yet pregnant.
Whatever your situation, know this: If you want a baby, you can't
assume it will just happen. As you're reading this, some six million
women and their husbands are facing infertility. They're wondering
what they need to do next to become pregnant, frustrated that they
didn't realize sooner just how big an impact age or medical problems
were going to have on their lives.
No matter how much the word "infertility" is in the air,
it is still a shock to realize that you are one of the ones who
can't just get pregnant when you want. First you may joke, "Guess
I didn't have to be quite so careful about birth control."
But gradually, you have to give up your fantasies"we'll
have our child in June, so I can take the summer off"and
confront the fact that, for you to have a baby, it is going to take
significant effort. As you undergo medical tests and treatments,
a new techno-vocabulary dominates your life and a new self-image-
patient -emerges. You have joined the 10 percent of U.S. couples
who will experience infertility at some point in their reproductive
lives.
The good news (if there's anything good to be said about infertility)
is that there is more real help available than ever before. But
there is also a lot of incompetent treatment out there, not to mention
hype. "Infertility care is a highly competitive, for- profit
business," points out Brian Kearney, Ph.D., a molecular geneticist
and author of High-Tech Conception: A Comprehensive Handbook for
Consumers. "You need to sort through what you hear and learn
to ask the right questions." Then, you can get the care that
has the best chance of working for you.
WHY ISN'T IT HAPPENING?
Given the exquisitely intricate orchestration of hormones and engineering
it requires, it seems astonishing anyone ever has a baby. Your egg,
triggered by release of just the right hormones, needs to mature
in the ovary, be released into the fallopian tube, then be fertilized
by a sperm, travel down the tube, and implant in the uterus, there
to grow to a seven-pound baby. That stunning complexity shows how
easy it is for a glitch in any part of the system to throw the process
off. Some of these malfunctions may have been with you since birth;
others are the legacy of infection, lifestyle, age, or, frustratingly,
factors no one can explain. While there are dozens of causes of
infertility (and, often, multiple reasons a couple can't conceive),
basically, these break down into a handful of categories:
OVULATORY DISORDERS Failure to ovulate
consistently (or at all) or to produce eggs capable of being fertilized
accounts for about one quarter of female infertility cases.
TUBAL PROBLEMS The fallopian tubes
may be damaged or blocked, say by adhesions resulting from past
infection (usually a sexually transmitted disease).
CERVICAL PROBLEMS Like Goldilocks's
porridge, the cervical mucus needed to help transport the sperm
to the egg has to be "just right": not too thin, not too
thick, not too acidic.
UTERINE ABNORMALITIES The lining may
not be thick enough for the egg to implant. Or you may have endometriosis,
where, for unknown reasons, the lining of the uterus grows outside
the uterus (in the fallopian tubes or abdominal cavity), possibly
impairing the movement of the egg through the fallopian tube or
causing hormonal or other disruptions.
MALE FACTORS These include a low sperm
count, sperm of poor quality (perhaps abnormally shaped), low motility
(sperm are too slow-moving), blocked or missing transport tubes
(which prevents sperm from reaching the ejaculate), or absence of
sperm altogether. There may also be a problem with the quality of
a man's semen, or there may be an infection.

Lori
& Ken Kreher: A Baby After Tragedy
It took the
most advanced techniques of reproductive medicineand a small
coincidencefor Lori and Ken Kreher to become the parents
of Blake Edward, born last January. In 1995, Ken, who has been
a paraplegic since a 1989 construction accident, was working with
a personal trainer, in hopes of making the U.S. Paralympics team.
Learning that the Krehers desperately wanted a second child (daughter
Kelli was 7 months old at the time of her father's accident and,
says Lori, "the only thing that kept Ken going then")
and that the method they were trying wasn't getting them anywhere,
the trainer suggested they contact another client of his, Sherman
J. Silber, M.D., a prominent fertility
specialist and director of the Infertility Center of St. Louis.
In a remarkable technique, doctors were able to extract sperm
directly from Ken's testicle and fertilize Lori's eggs through
ICSI. The first attempt failed, but three months later, when doctors
tried ZIFT (inserting five fertilized eggs into Lori's fallopian
tube), she became pregnant. "We just went wild," says
Lori. "It was such a good thing to finally happen."
|
For about one in five infertile couples,
however, no cause will be found, a condition known as "unexplained
infertility."
These problems can also kick in after you've had a child. Or a mild
abnormality might become more severe, making it difficult~r impossible-to
conceive again. Such "secondary infertility" can elicit
the same feelings of disappointment and frustration, tinged perhaps
by guilt that you're not satisfied with having one child.
WHEN SHOULD YOU SEE A DOCTOR?
Standard texts define infertility as the inability to become pregnant
after one year of regularly timed, unprotected intercourse. But you
don't have to wait for it to be "official." In fact, many
fertility experts believe that at six months, you might start exploring
whether something's wrong.
That exploration is going to take time. For a start, your ob/gyn may
have you chart your basal body temperature (the reading you get first
thing in the morning) or use a home ovulation-prediction kit for three
months, to see if you're ovulating regularly. Then you can't just
schedule all your diagnostic tests and procedures for, say, the first
week of December. Many of these tests (see chart at left) need to
be timed to a specific day in your cycle, and can't all be done in
the same month. Add in nonmedical delaysyou have to wait for
approval from your HMO, your husband is traveling-and you could be
eating up even more time.
Maybe this isn't a problem if you're in your twenties. But as you
reach your mid-thirties, you're looking at an increasingly narrow
window in which to conceiveeven narrower if you hope to have
more than one child.
WHY AGE COUNTS SO MUCH
At some point-if you're struggling to conceive-you'll probably find
yourself muttering, "Bet if I were an unmarried teenager, I'd
be pregnant by now." Actually, you'd be on to somethingnot
the marriage part, of course, but the youth. In your twenties, you
have a 20 to 25 percent chance of becoming pregnant each month. By
your forties, that drops to just 10 to 15 percent. Age is the factor
that, almost always, will drive the decisions couples have to make
about infertility treatments.
That is, your ageor, more precisely, the age of your eggs. When
you're born, your ovaries contain all the eggs you will ever have.
Each month after you reach puberty, if things are working properly,
a new egg will mature and be released, some 400 times in your lifetime.
Generally, however, the most fertilizable eggs are released earlier
in life, explains Sherman J.
Silber, M.D., director of the Infertility
Center of St. Louis at St. Luke's Hospital and author of How
to Get Pregnant with the New Technology.
The decline isn't completely steady: "Throughout your twenties
and early thirties, fertility drops gradually. But then, at 37, there's
a sharp falloff," says Dr. Silber.
What about your husband? Because a man is continually producing new
spermevery dayhis age doesn't influence his fertility.
But other factors do. Men who've had an STD may have blocked tubes,
so sperm are unable to travel from the testes, where they're manufactured,
to the urethra, where they join the ejaculate. A man may also have
been born without the necessary connecting tubes or be may have a
genetically derived form of infertility. Lifestyle figures in, too:
Alcohol, drugs, cigarettes, and a diet low in certain nutrients (zinc
especially) have all been shown to lower sperm counts or cause sperm
to become abnormally shaped.

IS
YOUR GYNECOLOGIST GOOD ENOUGH?
Chances are, when you first suspect a problem, you'll turn to the
ob/gyn you've been seeing for checkups. Certainly, the doctor should
be able to get you started on figuring out what's wrongconfirming
ovulation, doing blood tests or other preliminary diagnostic procedures.
He should also be able to refer your husband to a urologist for sperm
tests and semen analysis. Make sure the urologist is one who specializes
in male infertility, advises Theresa Venet Grant, president of INCIID
(the InterNational Council on Infertility Information Dissemination),
not a general urologist.
Many women stay with their gynecologists month after month, even for
years. And that could be a big mistakepossibly the biggest one
a couple makes. "The expertise of an infertility specialist can
make the difference between years of infertility and successful pregnancy,"
notes Diane Clapp, medical information director for Resolve, a national
information and advocacy organization for couples experiencing infertility.
Part of the problem may be the training, but part can also be attitudinal,
observes Christo Zouves, M.D., medical director of Pacific Fertility
Medical Center in San Francisco. "Doctors may be resistant to
suggesting high-tech approaches. They'll approach infertility treatment
with an attitude of 'let's try this, then this, then this...,' not
realizing that they're using up precious time, especially if a woman
is in her mid-thirties."
When should you leave your ob/gyn for a specialist? If you're 35 years
or older, advises Clapp, or if you have any of the following difficulties:
YOUR MENSTRUAL CYCLE is irregular, with
signs of irregular ovulation.
YOUR HUSBAND'S SEMEN analysis reveals
a low sperm count, low motility, or abnormally shaped sperm.
YOU HAVE A HISTORY of a pelvic infection.
YOU HAVE NOT BEEN ABLE TO CONCEIVE after
two years, even though basic tests have come back normal.
|
Suppose your doctor assures you that he or
she is a "fertility specialist"? There are some physicians
who "practically invented the field," says Grant, and who
gained all their experience in practice, not in academic training.
But unless you know that's the case, you should look for a board-certified
reproductive endocrinologist. If your ob/gyn can't refer you to one,
check The Official ARMS Directory of Board Certified Medical Specialists
(available in public libraries) or write to Resolve at 1310 Broadway,
Somerville, MA 02144 for a specialist in your area.
When you call a reproductive endocrinologist, make sure at least some
of the staff and technicians are available seven days a week. "If
they're not," says Grant, "you're clearly not in the hands
of someone whose priority is getting you pregnant." After all,
you may ovulate on a Saturday or Sunday, and need to be seen for tests
or treatments pinned to that day. What's more, if you have a regular
28-day cycle, the same thing will happen next month and the one after
and...
LOW-TECH ANSWERS
For most couples, relatively noninvasive techniques will work:
FERTILITY DRUGS If diagnostic tests show
that you have ovulation irregularities, your doctor will probably
suggest that you try the drug Clomid (clomiphene citrate, also marketed
as Serophene) and have scheduled sex based on when tests show you're
about to ovulate. ("If your doctor simply throws Clomid at you
without any testing," says Dr. Silber, "find another doctor.")
This is an okay game plan for a limited number of months, up to six,
some suggest. Others say even fewer. "If Clomid is going to work,"
says Dr. Zouves, "it will do it in three cycles." Unfortunately,
there are doctors who will urge women to keep trying with Clomid,
sometimes up to a yeara suggestion that not only won't help,
but could expose you to unnecessary danger, says Carolyn Runowicz,
M.D., director of the division of gynecologic oncology at the Albert
Einstein College of Medicine and Montefiore Medical Center in New
York. (Some studies have shown a link between fertility drugs and
ovarian cancer, but until we knowthe National Cancer Institute
is carrying out long-term studies nowcaution seems prudent.)
If Clomid doesn't work, your doctor may suggest using more powerful
ovulation-induction drugssuch as Pergonal (known chemically
as hMG, for human menopausal gonadotropin) or Fertinex (chemically,
FSH, for follicle-stimulating hormone) to be taken by injection at
home. While you're on these drugs, you need to be monitored with blood
tests to make sure hormone levels are rising properly. A few days
into treatment, you should also have a transvaginal ultrasound (a
sonogram done with a probe inserted vaginally) to check that follicles
in your ovary are maturing. Ultrasound is also necessary to check
that your ovaries are not becoming enlarged or producing too many
follicleswhich may lead to a potentially dangerous condition
known as ovarian hyperstimulation syndrome.

Jennifer
& Andrew Hale: Well Try Just Once More
The Hales knew shortly
after they were married in 1991 that they were going to need IVF:
Jennifer's tubes, tests had shown, were completely blocked. What
they didn't know, though, was that Andrew also had a problem,
something they learned three years later during their first IVF
affempt, when only two out of a dozen eggs were successfully fertilized.
Two more affempts (one with ICSI, one using frozen embryos) also
failed. At that point, the Hales thought they might turn to adoption.
But deciding to give IVF with ICSI one more shot, in 1997 they
consulted the Pacific Fertility Medical Center in San Francisco.
"This time we had an angel on our side," says Jennifer.
Last July 4, Julia Elizabeth Hale was born.
|
All these drugs, but especially hMG and FSH,
increase your chances of becoming pregnant with multiples. For couples
eager to have a baby, having more than one may sound even better (and
in a study several years ago, the vast majority of infertility patients
surveyed expressed a desire for twins, with half even liking the sound
of triplets!). But it's not ideal. Your pregnancy will be more complicated,
you'll be much more likely to deliver early, and the babies, as a
result of their prematurity, may face days, weeks, even months in
neonatal intensive care. Then, they're more likely to have developmental
disabilities.
INTRAUTERINE INSEMINATION (IUI) Sometimes
fertility drugs are used with an in-office procedure to achieve pregnancy.
In this, your husband produces a semen sample (by masturbation) and
the doctor treats and inserts the sample directly into your uterus.
If your husband also has fertility problems or tests have shown "penetration"
problems (his sperm fail to penetrate your egg), the doctor can mix
the sample with a variety of substances to help.
How long should you try IUI? Like Clomid, IUI usually works quickly
if it's going to work, says Dr. Silber. "If you haven't conceived
in several cycles, it's time to move on," he believes. Other
specialists may suggest trying for six months or even a year.
What you need to think about: IUI isn't cheap, costing anywhere from
an estimated $1,400 to $4,000 a month. Unless there's reason to believe
that sperm getting into the uterus is your problem, you might want
to cut your losses sooner. Moreover, each insemination cycle exposes
you to the potential risks of fertility drugs. By going quickly or
even directly to high-tech methods, you limit those risks.
HIGH-TECH
HELP
These are the superstars of infertility treatment, the procedures
that have made pregnancy possible for couples who, not long ago, had
no chances whateverwomen whose tubes are completely blocked,
for example, or men who produce no sperm at all. Basically, the treatments
all start the same way: A woman takes a series of different drugs
to stimulate ovulation (and to produce multiple eggs). Then, while
she's sedated, the doctor retrieves the eggs from the ovary.
Everything that follows egg retrievalwhere fertilization occurs,
how it's achieved, and at what point the fertilized eggs are transferred
back to the woman's bodyis a variation on a theme.
IN VITRO FERTILIZATION
With IVF, the retrieved eggs are placed in a glass (petri) dish, where
they mix with sperm provided by your husband. After two days, the
fertilized eggs (now known as embryos) are transferred back to your
uterus.
Who should consider it? IVF was developed
for women with blocked (or missing) fallopian tubes, and it's still
the procedure of choice for such women. But it's also used for other
problems, including unexplained infertility.
GAMETE INTRAFALLOPIAN TRANSFER
In GIFT, a woman's eggs are retrieved from the ovary, mixed with sperm,
then immediately placed in her fallopian tube, where fertilization
can take place as it does naturally.
Who should consider it? Women who have
at least one normal tube and whose husbands don't have significant
fertility problems.

Lisa
& Ira Daly: No Problem, But No Baby Either
When one of Lisa
Daly's closest friends asked Lisa to hold her newborn son at the
baby's bris (the Jewish rite of circumcision), Lisa initially
demurred. "It's good luck," her friend insisted. "It
means you'll have your baby soon." Could that be what would
work? Lisa, a registered nurse who specializes in monitoring high-risk
pregnancies, and her husband, Ira, now a social studies teacher,
had been trying to have a baby for five years. The Queens, New
York, couple had undergone test after test, and everything had
come back normal. They'd had surgery (a laparoscopy for her, repair
of a varicose vein on his testicle for him). Still no pregnancy.
Four attempts at intrauterine inseminations, with Clomid to boost
ovulation, also failed. Even more heartbreaking, Lisa became pregnant
once on her own, and once with Clomid, but miscarried both times.
"I just lost it after the second one," she admits. And
then, a month later, only two weeks after holding her friend's
baby, Lisa started another cycle of Clomid and on Rosh Hashanah,
the Jewish holy day of renewal, conceived her own son. Jacob Samuel
Daly was born on May 27,1997.

ZYGOTE
INTRAFALLOPIAN TRANSFER
You could think of ZIFT as IVF meets GIFTfertilization takes
place in a petri dish, but the fertilized eggs are transferred (before
they've become two-celled embryos) into the fallopian tube.
Who should consider it? ZIFT was developed
for cases where the woman has at least one normal tube and her husband
has fertility problems.
INTRACYTOPLASMIC SPERM INJECTION
ICSI is a truly stunning technique, where a single sperm is injected
into an egg. The process then continues as with IVF.
Who should consider it? Couples where
the problem is male-factor infertility.
CHOOSING A HIGH-TECH CENTER
If you didn't like high-school math, you're going to have a tough
time decoding the numbers that fertility centers tout as the basis
of their success rates. But it's more than worth the effort: IVF and
its relatives are physically and emotionally demanding procedures,
not to mention extremely expensive. Why use up your few chances to
get pregnant at a center that isn't experienced in your problem or
that hasn't had much success generally?
Fortunately, you have help: The Assisted Reproductive Technology Success
Rates, a compendium of results from 300 or so clinics that are members
of the Society for Assisted Reproductive Technology (SART). You can
order copies by phone (888- 299-1585) or click on to the World Wide
Web (Actually, it will take lots of clicks: The directory prints Out
in three parts, 150 pages each.) And note: As of this printing, the
directory currently available is based on 1995 records; the 1996 edition
is expected to be available by year's end. Also, starting with the
1996 directory, centers will be audited (on a random basis) as part
of a government crackdown on misleading claims and practices at fertility
clinics.
How do you interpret the numbers each center presents? Unscrupulous
practitioners would probably like you to focus on one figure only:
The number of live births achieved after embryos have been transferred
to the mother's womb. Why not? By definition, that has to be the highest
figure, since it would eliminate from consideration all those cycles
that had to be canceled at earlier points in the process because things
hadn't gone wellthe woman had failed to produce enough good
eggs, for example, or the eggs had failed to fertilize.
So the figure that's generally most meaningful is the one that's most
comprehensive: Number of live births per cycles initiated, a figure
that's popularly called the "take-home baby rate." But even
that number isn't as revealing as it sounds. Smaller, local centers,
for example, may treat couples from the area. If the woman becomes
pregnant, fine. If she doesn't, though, she may move on to a larger
clinic, which handles more difficult cases, explains Zev Rosenwaks,
M.D., director of the Center for Reproductive Medicine and Infertility
at New York Hospital-Cornell Medical Center in New York. The smaller
center ends up with a high success ratebut all that reflects
is the fact that the clinic's largely treating couples who get pregnant
more easily.
Other more insidious practices can be at work too. Centers have a
great stake in publishing high success rates: They could, therefore,
be bumping up couples with "easier" cases to the top of
a waiting list, in hopes their higher odds will raise the center's
overall success rates. Or centers could be rejecting couples with
severe problems or assigning such couples to a "research group,"
so their numbers will be kept out of the overall rates. Conversely,
centers whose figures seem on the low side may be more accepting of
such difficult cases.
|
But if you can't totally rely on the numbers,
what can you look at?
EXPERIENCE "Centers where thousands
of IVF cycles have been performed and many hundreds or thousands of
women have become pregnant almost surely have mastered IVF,"
says Joseph D. Schulman, M.D., director of the Genetics & IVF
Institute in Fairfax, Virginia. And look for experience in your particular
problem, advises Dr. Kearney.
NITTY-GRITTY NUMBERS Knowing certain
specifics can signal whether a center is top-notch. Find out what
percent of cycles a center cancels, advises Dr. Silber. "If the
cancellation rate's higher than 15 to 20 percent in women under 39,
that's a red flag," he warns. Similarly, if a center is doing
ICSI, embryos should be placed back in the womb successfully nearly
all the time. "Failure should occur less than 2 percent of the
time," says Dr. Silber, "and only in patients with few or
poor eggs.
COMPLICATION RATES High numbers of complications
signal that a center may not be paying close enough attention. You
could ask specifically about ovarian hyperstimulation risk, suggests
Dr. Rosenwaks. "With careful monitoring, a center's rate should
be exceedingly low, less than 1 percent."
INNOVATION You may not need to take advantage
of any "firsts" a center has achieved, but being on the
cutting edge of medical advances almost always implies a high degree
of skill and knowledge, says Dr. Schulman.
QUESTIONS YOU WISH YOU DIDN'T HAVE
TO THINK ABOUT
It's hard enough to realize that you're not going to be able to conceive
the "regular" way. On top of that, couples turning to high-tech
procedures may have to grapple with difficult issues.
ARE HIGH-TECH BABIES HEALTHY? Generally,
IVF babies are no more likely to suffer birth defects or other abnormalities,
studies show. But male babies conceived through ICSI do have a higher
risk of certain genetic defects. The reason: Men who have extreme
infertility problems (very low sperm counts or no sperm at all) may
have an inherited defect on their Y-chromosome, which they in turn
may pass to their sons.
TOO MANY BABIES? In 1995, 28 percent
of all assisted-reproductive technology births were twins, triplets,
or higher- order births, according to the SART figures. You can avoid
the risk of multiple births by limiting the number of embryos that
are transferred back to the mother. But then you also cut the chances
of success. Is there a happy medium, so to speak? Going beyond mere
numbers, some specialists believe that checking the quality of embryos
might be the ticket. Last spring, for example, the Northwest Center
for Infertility and Reproductive Endocrinology in Margate, Florida,
reported that they'd found the best "formula" for maximizing
pregnancy rates while limiting higher-order (triplets or more) multiple
conceptions:
For women 35 or younger, transfer up
to four poor-quality, two fair-quality, or two good-quality embryos.
For women 36 to 39, four poor-quality,
three fair-quality, or two good-quality embryos.
For women 40 and older, transfer five
embryos, regardless of quality (any lower, the chances of success
are too low).
WHAT ABOUT MULTIFETAL REDUCTION? One
way around the problem of multiple births is to transfer a larger
number of embryos, then "reduce" the number early in pregnancy
(by injecting one or more fetuses with a solution that causes them
to die). Aside from the painful emotional issues reduction raises,
it is not a panacea: While it does cut your risks, in a study comparing
"reduced" twins (from quadruplets) with twins that started
out that way, the reduced twins averaged lower weights at birth and
were more likely to be delivered early, possibly because of complications
from the reduction procedure itself or possibly because of problems
related to the implantation of a larger number of fetuses to begin
with.
HOW LONG SHOULD YOU TRY? IVF is not like
rolling dice, Dr. Kearney explains, where the more rolls, the greater
your odds of success. Rather, couples with the fewest problems are
more likely to get pregnant ''on an earlier throw"; those who
are older or who have more medical problems are less likely. Nor,
obviously, do such couples' chances improve with time.
Finances aside (though with IVF averaging $8,000 to $10,000 per cycle,
few couples can put finances aside), the latest numbers suggest that
it's worth trying at least three cycles. A just-released SART study
found that success rates remain almost equal for the first two cycles
of IVF, and then decline only modestly. After more than four cycles,
however, pregnancy rates drop significantly. At that point, couples
may want to explore other technologies (such as using donor eggs)
or turn their energies to other ways of creating a family or having
children in their lives.
