Mobile Phone Helps You Track Fertility Days

While infertility in men was blamed on heat and electromagnetic radiation in mobile phones earlier this month, a new mobile phone available via Japan's NTT DoCoMo alerts female consumers when they've reached their most fertile time of the month.

According to a Reuters, a pill-shaped mobile phone lets out a special ring three days before ovulation, and on the day of. The phone calculates these days based on the woman's menstruation cycle each month, but they do warn those figures are based on average cycles—which means this feature is more gimmick than function. The phone also hopes to attract females with girly features such as a recipe database.

This is not the first phone that promises to track a woman's ovulation pattern, and certainly won't be the last now that Japan's fertility rate is on the decline. Previous female-centric lifestyle phones also included frivolous options such as a built-in shopping lists, fat calculators, mirrors, fragrance dispenser, biorhythms, and conception calendars.

Phones aren't the only gadgets that alert you to fertility cycles. Last month, I wrote about the Baby Boom Watch, which tracks fertile days, pregnancy weeks, and even helps you find a baby name. If you want a cheaper alternative that basically does the same thing fertility gadgets do, check out the Ovulation Predictor Calculator.

Girls, what do you think? Would you buy a phone that tracks your ovulation and menstrual cycle?
