Feeling Fertile?

Of no real use to me, but still a cool gadget.

The OV-Watch is a $99 wristworn sensor that measures the salts in the wearer's sweat to identify when she's most fertile.



From the product page:

Researchers in the late 50s and early 60s noted that numerous salts (chloride, sodium, potassium) in a woman's sweat fluctuated in relation to the menstrual cycle. Chloride levels are low at the start of the menstrual cycle and peak three times during the cycle. Using a patented biosensor, OV-Watch detects a baseline chloride ion level for each woman and then accurately predicts ovulation based on the timing of the first peak. The OV-Watch detects the chloride surge 3 days prior to the estrogen surge, 4 days prior to the LH surge and 5 days prior to ovulation, making it an earlier predictor of ovulation than any other chemical surge during the month. During the clinical trials for FDA approval with Dr. Arthur Haney at Duke University, approximately 3 out of 4 women received the full 5 day notice of ovulation while only 1 in 6 women were given more than 12 to 24 hours notice with urine tests or LH kits.

Uhm.... yeah right. Don't believe in that. There's a kit you can buy that will tell you when you ovulate. I think that's much more accurate.

[kingy]

it doesnt look like it actually tells you the time.

[/FONT]  Women dress better when they are most fertile, according to a study published online last week in the journal Hormones and Behavior.  Using 30 college-age women as subjects, five researchers had a panel of 42 men and women compare photos of the women taken both when they were ovulating and when they were not, asking in which photo each woman looked more attractive. Sixty percent of the time, the panel chose the photos of the women taken when they were most fertile.  In an interview, the study's lead author, Martie Haselton, called the findings "highly statistically significant" and said, "We know the effects have something to do with ovulation." She added that the judges thought the women dressed increasingly attractively the closer they were to their most fertile day.  While other species emit scents or display other physical changes when they are ready to mate, researchers have traditionally assumed humans conceal their fertility, the paper's authors wrote. They added that their work suggests that ovulating women engage in "self-ornamentation through attentive personal grooming and attractive choice of dress."  "It's just showing us our evolution, our biology, is showing up in even the most modern of behaviors," said Haselton, a scientist at the Center for Behavior, Evolution and Culture at UCLA.  The researchers were uncertain what was motivating these women, however: whether ovulating women may be trying to attract mates beyond their primary partners or simply reflecting a mood change, they wrote.
