MIAMI – An international team of researchers has discovered a mutation in a single gene that appears to account for a form of male infertility, specifically the inability to produce sperm.
“In a population of a thousand men they found out that they can have an underlying genetic defect that blocks the maturation of sperm from its first inception all the way to producing mature sperm,” said Dr. Ranjith Ramasamy, director of male reproductive medicine at UHealth.
Understanding how the gene functions may help provide treatment for men with the condition and lead to new methods of male contraception.
Resistance for fat shedding
And in other health news, a new study into exercise is shedding light on how resistance training can help shed fat.
Researchers have found that resistance-like exercises, including weight training, regulate fat cell metabolism at a molecular level.
The studies in both mice and humans showed that when under resistance, muscle cells release particles that move fat cells into a fat-burning mode.
