Only one out of eight couples have trouble getting pregnant or carrying a pregnancy to term.

According to an NBC report, that one-out-of-eight translates to just 12 percent of women, but as prospective mothers age, that percentage is growing higher—and those prospective mothers are turning to in-vitro fertilization to make their ambitions come true. And, according to the report, about one out of every 60 newborns come into the world by way of IVF.

But insurance coverage for the process is still limited. A Mercer study this year found that only 26 percent of companies with over 500 employees cover the procedure. And that drives many Americans paying the entire expense fully out of pocket—which is not only driving costs higher, but making the process riskier.
