Research by Matthew Hardy and colleagues found that stress hormones overpower the enzymes responsible for producing testosterone in testes, leading to a suppression of sperm formation. The study provides insight into male reproduction and may aid the design of new male contraceptives.
Researchers found that high 'free' testosterone levels in adulthood and a small shoulder span may be related to hormone levels at various stages of development, suggesting a link between these factors and prostate cancer risk. Further study is needed to confirm these findings.
A Georgia State University study found that higher testosterone levels are related to violent crimes and aggressive behavior in women's prisons. The study also discovered that low testosterone was associated with manipulative and sneaky behavior, suggesting a link between hormone levels and dominance.
A recent Penn State study found that high-carbohydrate, low-fat diets may cause a drop in testosterone levels due to inadequate nutrient balance. The study revealed a positive correlation between dietary fat and resting testosterone levels before and after exercise.
Researchers at the University of Chicago Medical Center have found that testosterone can shrink experimental human prostate tumors that no longer depend on the hormone. This suggests a potential new approach for treating advanced prostate cancer.
A new study by Johns Hopkins Medicine reveals that testosterone replacement therapy may improve visual and spatial skills, as well as verbal fluency and memory in men with low testosterone. The findings suggest a potential role for testosterone in cognitive function and brain function.
A Johns Hopkins study found that declining testosterone levels in HIV-positive men can predict weight loss and increased risk of death. Researchers measured testosterone in 26 men and discovered a significant decline in hormone levels among those who experienced weight loss.
