A startup founded by SolarCity and Google alums wants to tell you your 'fertility age' — here's what that means

As a result, the fertility market has grown to about $3 billion in the US. According to FertilityIQ, the cost of one cycle of in-vitro fertilization, is on average $23,474 in the US, and it often takes more than one cycle to work.

Now one mother, , who previously worked as a director of product marketing at SolarCity, is teaming up with Google alumni and medical advisers from Stanford University to guide families through the fertility process.

Called Future Family, the company aims to help women find their "fertility age," provide concierge care to help women navigate their treatment options, and offer financial packages to cover the cost of those treatments.

Heres what the Future Family process looks like

There are a number of companies breaking into the fertility space, from egg-freezing services to fertility clinics. Future Family wants to fit in outside of the clinics, Tomkins said. That's done in three ways:

The "Fertility Age" test
will cost $299
nurse concierge care
financing packages

What a fertility age test can and cant tell you

While the test doesn't provide you an actual "age," it can provide a snapshot of your egg quantity. The blood test looks at three hormones that are commonly screened for in the fertility process: FSH, Estradiol 2, and AMH.

If the results for any of the three hormones aren't in the normal range, it could mean that the woman will have more difficulty conceiving. Using the data from those three tests, experts can determine how many eggs a woman might have left.

"It’s a guesstimate of your eggs," Dr. Ebbie Stewart, the chair of reproductive endocrinology at the Mayo Clinic (who is not affiliated with Future Family) told Business Insider.

But there are limitations to the test, Stewart said. For one, it can't give you details about the quality of those eggs. Say you take the blood test when you're 25 and again when you're 44. You might come back with the same numbers, but the quality of those eggs will be very different.

Another limitation with the FSH and Estradiol tests: Those hormone levels fluctuate quite often, which could make it more difficult to get the right snapshot of what's going on with a women's eggs. That could incite panic in women who don't need to panic, or falsely reassure a woman of their fertility without considering other factors, such as age and medical history.

The limitations of the blood test are something Future Family is aware of. "There isn’t a perfect test to tell how your ovaries are functioning," Dr. Lynn Westphal, a professor of reproductive endocrinology and infertility at Stanford and medical adviser to Future Family, told Business Insider.

But, Stewart said, having the tests available through an online order could provide some women with additional information about their fertility sooner than they might have otherwise received it.

A dramatically changing field

The way people are planning out families right now is contributing to a "looming healthcare crisis for the millennial generation," Tomkins said — one that could be incredibly expensive.

Westphal, who got involved with egg freezing almost 20 years ago to help preserve fertility for women undergoing chemotherapy, said she's seen interest in the procedure change "dramatically" in the last few years, especially among women who are doing it electively. Some companies have started offering the service as a benefit to women who might be considering the process, even though they have no health issues that would make it medically necessary.

Even with medical advancements to both IVF and egg freezing, there are no guarantees that the procedures will pay off. Even if you have your eggs frozen — a process can cost around $50,000 — there's a chance you might not need them. And even if you do use them, it's not a fool-proof insurance policy.

"People talk about 'egg banking' as though it’s insurance," Hilda Bastian, chief editor at PubMed wrote in a November 2016 blog post. "I think both 'banking' and “insurance' are misleading ways to look at this. This language gives an impression of more security than freezing eggs can deliver. And it doesn’t convey the health and emotional risks."

It's opening up the industry for different approaches to pay for these treatments, including monthly payments for egg-freezing and IVF packages that have money-back guarantees, one that will likely continue to grow in the coming years.
