Trying to pregnant, but can't seem to get the timing right? Well, this new "paisley pink" phone from Japanese company DoCoMo gives a whole new meaning to the booty call. Basically, a woman inputs data about her menstrual cycle into the phone, and when the time is ripe, er, when she is at her most fertile, the phone will send her an alert. (Giving her a few days notice, a nice touch.)

Other features include a recipe database (for the wooing part I guess) and a button you can press when you need to fake an incoming call. (All cell phones should have that!)

So basically, this phone really puts the woman in control--she knows when she's fertile, and she can use the fake call button to replace the headache excuse when she's not in the mood. In other news: a recent study links cellphone use with male infertility, so potential fathers should probably keep their conversations short.
