A little bit of testosterone cream might help women run faster longer, a new study suggests.
Some female athletes have naturally high testosterone levels that are similar to men, and there is controversy over whether it's fair to allow them to compete against female athletes with normal testosterone levels.
There's a lack of clear evidence on how testosterone levels affect ...
Running contrary to current guidelines, new research suggests that use of hormone-suppressing treatment over the long term may not help some men battling recurrent prostate cancer, and may even cause harm.
In fact, the study found that long-term hormone therapy was tied to a raised risk of death from other causes for some patients who received it.
When men have both advanced prostate cancer and heart disease, treatment may pose a dilemma: Newer hormonal therapies that can slow the cancer down might also be risky for their hearts, a new study finds.
Once prostate cancer spreads beyond the gland, one of the mainstays of treatment is hormone therapy. The aim is to prevent androgens ("male" hormones such as testosterone) from feedi...
SATURDAY, May 4, 2019 (HealthDay News) -- Buyer beware: When it comes to testosterone supplements, men should know a new study finds there is precious little evidence to support claims they will boost testosterone levels, sex drive, strength and overall energy.
To come to this conclusion, the researchers first broke down 50 testosterone supplements into th...
Polycystic ovary syndrome is a common cause of infertility and type 2 diabetes, but little is known about its origins. Now, new research suggests a gene involved in male hormone production plays a big role in the disorder's development.
"We're starting to make headway on what causes PCOS [polycystic ovary syndrome]. It's very frustrating for patients because it's poorly understood," ...
When couples experience recurrent pregnancy loss, it's natural for them to want to know why. Now, a new study suggests that sperm DNA damage could be a factor.
Recurrent pregnancy loss is defined as the consecutive loss of three or more pregnancies before 20 weeks' gestation. It affects up to 2 percent of couples and, in many cases, it is difficult to ident...
Hormonal treatment can help control prostate cancer but may increase a man's risk of depression, a new study by Danish researchers suggests.
Male hormones, such as testosterone, are known to fuel the growth of prostate tumors. So doctors use drugs to reduce hormone production. But that can bring on tough side effects, such as incontinence or impotence.
Having a twin brother could put a woman at a lasting disadvantage, and exposure to his testosterone before birth may play a role, a new study suggests.
Researchers analyzed data on 13,800 twin births in Norway between 1967 and 1978. Compared to women with a twin sister, those with a twin brother were 15 percent less likely to finish high school and nearly 4 percent less likely to com...
High testosterone levels can drastically increase a man's risk of heart failure and stroke-causing blood clots, a new study reports.
Men with a genetic predisposition to high testosterone levels have a nearly eightfold increased risk of heart failure and twice the risk of thromboembolism (blood clots that can block veins or arteries leading to the brain or lungs), researchers found.
Weight-loss surgery may have a side benefit that most don't know about, with new research showing testosterone levels in male patients jump after the procedure is done.
Obesity can lead to lower testosterone levels, lower sexual satisfaction and reduced fertility in men, the study authors explained. A man's fertility declines an average of 10 percent for every 20 pounds he is overweig...
The "low-T" craze appears to be waning, with fewer men in the United States turning to testosterone therapy as a way to stave off aging and sexual decline.
A steep decrease in testosterone prescriptions occurred between 2013 and 2016, coinciding with public warnings that hormone therapy could increase men's risk of heart health issues and prostate cancer.
Men with localized high-risk prostate cancer can slow its spread by using a cancer drug that's already on the market, a new clinical trial shows.
The targeted drug enzalutamide (Xtandi) reduced by 71 percent these men's risk of either dying from their prostate cancer or having the cancer spread to other organs, compared against a placebo. The drug also delayed their prostate cancer's ...
A low sperm count may do more than affect a man's ability to have children. It also may be linked to a number of health problems, new research suggests.
A study of nearly 5,200 Italian men found that those with low sperm counts were 1.2 times more likely to have more body fat, higher blood pressure, higher bad cholesterol and triglycerides, and lower levels of good cholesterol.
