Obesity impacts male fertility, doctors say

MIAMI – Data show that men around the world are experiencing fertility problems, but in many cases the solution may be simple.

Dr. Ranjith Ramasamy, the director of Reproductive Urology at the University of Miami’s Miller School of Medicine, said a recent study found that men can double their sperm count if they lose weight and maintain weight.

“In overweight men, their testosterone levels, which are the male hormone, are typically low. And if there are low testosterone levels made by the testes who also make sperm which tells us you do not have enough testosterone to make all the sperm you possibly can. “So in men who lose weight, the testosterone levels that the body produces typically go up and this probably also drives the increase in sperm count,” Ramasamy said.

This is the first long-term randomized study showing improved sperm quality with a sustained weight loss of 36 pounds or more in obese men.


Breast cancer

Researchers are encouraged by some of the findings of a new drug to combat breast cancer.

The drug Enhertu is an intravenous antibody-chemotherapy combination.

Researchers compared it to standard chemotherapy in HER2-positive breast cancer patients who could not be treated with surgery.

The study found the drug stopped the progression of cancer for ten months compared to about five and a half months for the group that received standard chemo.

Enhertu also improved survival by about six months.
