Hopeful parents are willing to spend tens of thousands of dollars on fertility treatments, but there is an old fashion method that is getting a high tech twist.

While some parents are able to have a baby the old-fashioned way, for other Bay Area couples, getting pregnant can become difficult and stressful as careers delay parenthood and biological clocks tick away.

"They couldn't ever tell me exactly what was wrong with me, they basically said I was too old," said 41-year-old Kirsten Moore. 

She and her husband, Dan, have spent three years trying to make a baby. They tried herbalists, acupuncture and then multiple rounds of assisted fertility treatments.

"Early on in the process our biggest problem was finding out exactly when she was ovulating it was really hard to pinpoint the date," said Dan.

For generations, women have used body temperature to track fertility. A woman's lowest low-temperature of the month signals ovulation. But catching that precise time can be tricky.

KTVU Health and Science Editor John Fowler found a potential high-tech solution. It is a fertility monitoring service called Duo-Fertility.

Co-developer Oriane Chausiaux has a Ph.D. in the genetics of infertility. Chausiaux and a team of analysts are currently watching the ovulation cycles of a population of over 2,000 woman to build a database to compare the cycle of new clients.

By comparing a woman's cycle to others, they are able to predict the best time to conceive. Duo-Fertility claims to have an independent study the accuracy of their program which they say is 100%.

Duo-Fertility is a stick-on a wireless thermometer recording body temperature every five seconds. The reader sends temperature and other vitals by internet to analysts which generates a statistical model predicting a woman's fertility cycle.

"It's easy to use and it's simple so everybody can understand what's happening," said Chausiaux.

Pharmacist Helen Egan said she had her daughter Alexia three months ago.  After three frustrating years, her doctors were advising in vitro fertilization. Instead, she tried Duo-Fertility.

"And within eight weeks I was pregnant," said Egan.

Duo-Fertility said it does not replace medical intervention for women with physical problems. $800 buys a year's monitoring with Duo-Fertility.

Dr. Laurie Green, an obstetrician at California Pacific Medical Clinic. Dr. Green believes a thermometer and graph paper should work almost as well.

"I think this one's a little overhyped. It takes something you can do low tech and creates a high-tech solution," said Dr. Green. "$800 dollars is a lot of money to spend for something you can figure out yourself, just by studying your own patterns."

Kirsten and Dan Moore said they had trouble predicting Kirsten's patterns. After intrauterine insemination then in vitro fertilization, she did get pregnant.

Kirsten said the medication alone was at least $600 for each dose for the IUI treatment.  For IVF, it cost them thousands of dollars more. They believe even at $800, early high-tech help might have saved them money.

"If there's a high probability you're going to be successful in the early phases using that, then it's cost effective," said Dan.

The Moores just had their new baby this week. They had a 7-pound 14-ounce baby boy they named Johnathan James or "JJ" for short.
