Is it a phone call, a text message or simply time to make love? A new mobile phone available through Japan’s NTT DoCoMo can ring to let would-be mothers know when they reach the most fertile part of their monthly reproductive cycles. By tapping in data on menstruation dates, the user can program the phone to alert her three days before ovulation and again on the day.

I wonder if they can set the ringtone to play Bad Company’s “Feel Like Making Love”?
