New research has found that the U.K. was determined to be home to the highest number of obese women in all of Europe. But it still can't top the U.S.

Between the ages of 20-29, testosterone levels drop for all men. Men without children have a 12 to 15 percent decrease in testosterone, while men with a baby between one month and a year old have a 30 percent decrease. Those with infants younger than one month old experience the greatest decline, with levels four to five times lower than men with no children and twice as low as fathers of older children.

It is the expected norm within the medical community that women -- especially those over 40 or with a family history of breast cancer -- should get their annual mammography without fail.  But how effective of a tool is it in actually saving lives? According to a recent study by an international team of researchers at various European institutions, the answer is that it's not especially effective.  Breast cancer screening was not shown to have a major impact on the reduction of breast cancer mortality in the recent past.  While the mortality rates from breast cancer have certainly gone down in most developed countries in the last two decades, it would seem that the lower numbers might not be attributable to mammography.

A new study has found Botox reduces the ability to empathize. The reason is that in order to interpret the emotions others express, we need to mimic those emotions in our own facial expression. The mimicry happens fast and it's quite unconscious -- just a flicker. But if you can't do it, you can't mimic others' emotions.

A new study at the University of Colorado in Aurora has found that liposuction is not permanent. One year post-surgery, for all of the women in the study, all of the fat that had been removed -- an average of 5.8 pounds per woman -- had come back. But curiously, it did not return to its original site on the body. Instead of on the thighs or lower abdomen from where it had originally been removed, the fat was redistributed to the subjects' upper abdomens or around the shoulders and triceps.

A new study has shown that approximately half of all adult men are infected with HPV. The participants were residents of the United States, Brazil, and Mexico, and the mean age among them was 32 years old. The rates of HPV infection discovered were high in men of every age. The findings also showed that the immune systems of older men were typically able to clear up HPV infections faster than those in younger men. And, unsurprisingly, certain strains of HPV that can cause cancer were highest in men with more than one sexual partner at a time.

In the early 2000s, the YAZ® birth control pill hit the American market in a huge advertising blitz claiming that YAZ® was not only the primo, number-one birth control pill in the world (backed by studies), but also offered the additional benefits of eliminating acne and reducing the effects of PMS/PMDD. Unfortunately, YAZ® comes with a host of side effects -- all blithely laughed off at the end of the ads. A few years down the road, and now many women wished they had paid more attention to those warnings.

Research out of the John Wayne Cancer Institute has shown that  for women who are in the early stages of breast cancer and where evidence of its spread is limited to only one or two nearby lymph nodes, having more extensive surgery does not improve survival rates or lessen the recurrence of cancer over a period of five years.  Read on for more information about alternative cancer therapies instead of breast cancer surgery recommendations with this health blog!
