As
the rate of first-time moms over age 35 rises—it’s up to 15 percent in
the U.S. now—so does the country’s reliance on in-vitro fertilization.
In fact, what was once a last-resort procedure has become increasingly
routine: In 2012, U.S. doctors performed 165,172 fertility
procedures—more than 99 percent of which were IVF, according to the most
recent data from the Society for Assisted Reproductive Technology, reflecting a 7 percent increase over 2011.
And how many of those procedures
actually lead to deliveries? Among women younger than 35, the data
shows that 46 percent of the embryo transfers resulted in live births.
That number drops to 38 percent for women ages 35 to 37, and 28 percent
for women ages 38 to 40.
Although those stats may sound
discouraging, consider this
: Only 55 percent of “chromosomally normal”
embryos successfully become a baby, “whether you make them at home in
bed, or whether you make them in a lab,” Jamie Grifo, M.D., program
director of the NYU Fertility Center, told Yahoo Health. “It’s mostly
not under your control. It’s about the luck of getting a good embryo.”
But that doesn’t mean the only
way to boost your chances of success is to cross your fingers and hope
for the best. “There are things the patients can do themselves to
actually improve the odds of IVF,” A. Musa Zamah, M.D., an infertility
expert at the University of Illinois at Chicago, told Yahoo Health. “And
I don’t think those things are always fully utilized.”
Kick stress to the curb
Don’t stress too much about
de-stressing — just devote a few minutes every day to unwinding without
totally checking out from your daily routine. “Just because you’re
stressed doesn’t mean you can’t get pregnant,” Grifo said. “If that were
true, nobody in New York would have a baby.” In fact, he said,
eliminating every source of anxiety — say, by quitting your job
— may just leave you without a distraction, tempting you to fret 24/7
about getting pregnant (which is, in and of itself, a serious stressor).
That said, mental tension
definitely doesn’t do your fertility any favors, since being in chronic
fight-or-flight mode can compromise the quality of your eggs, Grifo
said. Plus, the stress hormone cortisol may interfere with implantation,
while also blocking estrogen action in your endometrium, said Sarah
Berga, M.D., the chair of obstetrics and gynecology at Wake Forest
University.
Easing stress, on the other hand, may actually help speed things along: In a 2011 Fertility & Sterility study, women who watched a clown perform
magic tricks for about 15 minutes after undergoing IVF were nearly
three times more likely to become pregnant than the control group. So
figure out what works for you — knitting, yoga, watching funny cat
videos, whatever — and commit to doing it daily.
Resist the urge to over-exercise.
Being fit equals higher
fertility, so constantly hitting the gym is a step in the right
direction, right? Not necessarily. Exercise is a form of
physiological stress, which means too much of it could hurt your
pregnancy odds, noted Grifo. “If you’re running 60 miles a week or
training for a marathon, that’s not a good thing,” he said. “If you’re
doing an hour of cardio, seven days a week, that’s not a good thing.”
You should be especially
cautious about high-intensity workouts during the actual stimulation
phase of IVF, when you’re receiving hormone injections, said Zamah. “You
don’t want to risk the ovaries twisting,” he explained. So what’s a
reasonable workout regimen? Grifo recommended 30 to 40 minutes of cardio three times a week, with yoga or light weightlifting on the days in between.
Load up on vitamin D.
It’s not just folic acid
you should be popping: Consider taking a dose of D, too. “Vitamin D has
long been thought to be primarily important for bone health,” said
Zamah. “But it can really affect all aspects of health, including
reproduction.” In fact, a 2014 study in the journal Human Reproduction found
that D-deficient women who underwent IVF had a 39 percent lower chance
of pregnancy than ladies with normal levels of the vitamin. Although the
reverse isn’t yet proven — that taking D boosts your pregnancy odds —
supplementing with 400 to 800 IUs of vitamin D per day could be
“potentially beneficial,” Zamah said.
Establish a healthy weight — before attempting IVF.
Don’t wait until you’re ready to
start trying for a child to worry about the number you see on the
scale. “Doctors might be reluctant to bring this up with patients, but
weight can impact the success of IVF,” Zamah said. Specifically, being
overweight has been linked to poor IVF outcomes, including decreased
pregnancy rate, lower live birth rate, and increased risk of
miscarriage. The likely explanation? “Obesity appears to hurt the eggs
and maybe the endometrium,” said Berga.
So before you start IVF, aim to
get your weight into the “normal” BMI range, or as close to it as
possible. “Even if you’re not fully in the ‘normal’ range, a 5 to 10
percent reduction in body weight can really be beneficial for IVF
outcomes,” Berga told Yahoo Health. Just don’t go too far — being
underweight can have a similarly negative effect on pregnancy success.
Consider a DHEA supplement
A third of all IVF centers
across the globe now use DHEA, a hormonal supplement shown to boost
pregnancy chances in women with a shortage of viable eggs, according to a
recent study review in Reproductive Biology and Endocrinology. How
does it work? “DHEA might help the ovary respond to the fertility
medications,” particularly in patients with a low number of eggs,
explained Zhama. The suggested dose: 25 milligrams, three times a day.
Get the guy involved
Your body carries the baby, but
his sperm also plays a role in your IVF odds. “The male partner needs
some attention, too,” said Berga. In addition to him limiting his stress
and watching his weight, your partner (or donor) can also try a more
targeted approach to boosting the health of his swimmers: by popping
multivitamins, plus an antioxidant supplement. “Nobody has shown one
antioxidant blend to be superior to another for sperm,” Zamah said. “But
there are multiple studies showing at least a potential benefit on
sperm parameters.”
