With more American men turning to testosterone therapy as a way to boost energy levels, build muscle and tackle erectile dysfunction, it's no wonder that web-based merchants have stepped into the breach, seeking to grab market share away from doctors and pharmacies.
But are online testosterone purchases safe? No, a new investigation warns.
Men with low testosterone levels may be more likely to have more severe illness when infected with COVID-19, according to a new study.
Treating men who have low testosterone with hormone therapy may reduce their risk of serious illness from COVID, researchers said, but it comes with other risks that doctors and patients will need to weigh.
Hormone therapy is a common treatment option for prostate cancer, but it may increase the risk of death from heart disease, especially in older men, a new study finds.
Dr. William Dahut, a prostate cancer researcher and chief scientific officer for the American Cancer Society, said the study from Lithuania provides more evidence that starting hormonal therapy requires careful thought, par...
One year of testosterone therapy for men with low levels of the hormone does not appear to increase their risk for heart problems, British researchers found.
"We were unable to find evidence ... that testosterone increases risks of mortality or cardiovascular and/or cerebrovascular [heart and/or stroke] events in the short- to medium-term in men with low testosterone," said study leader D...
TUESDAY, Jan. 18, 2022 (HealthDay Now) -- Advanced forms of hormone therapy are very effective at keeping prostate cancer in check, but they also can double a man's risk of falling into depression, researchers have found.
Prostate cancer patients treated with the latest forms of hormone blockers were twice as likely to develop depression compared with men treated with older forms of hormo...
People who were exposed to a particular hormonal medication in the womb may have a heightened risk of cancer later in life, a new study suggests.
Researchers found the increased cancer risk among adults whose mothers had been given injections of a synthetic progesterone known as 17-OHPC, or 17P, during pregnancy. The study participants were born in the 1960s, when the drug was used to hel...
What launches guys on serial sexual conquests and prompts solo activity among women?
It's testosterone, of course.
As the primary male sex hormone, it plays a leading role in the sexual development of guys. But folks often overlook the role it plays in female sexuality. Yes, women have testosterone, too, though much less of it -- and it exerts a far different pull,
Higher levels of testosterone don't give men or women an edge in life, claims a new study that challenges a common belief.
"There's a widespread belief that a person's testosterone can affect where they end up in life. Our results suggest that, despite a lot of mythology surrounding testosterone, its social implications may have been overstated," said Amanda Hughes, a senior research ass...
Men with low testosterone levels have a much higher risk of severe illness and death from COVID-19, a new study from Italy finds.
The study included nearly 300 symptomatic male COVID-19 patients who arrived at the emergency department and were admitted to San Raffaele University Hospital in Milan during the first wave of the pandemic.
The lower the patients' levels of the hormone te...
Low testosterone levels may increase men's risk of severe COVID-19, according to a new study.
On average, men fare worse with COVID-19 than women.
"During the pandemic, there has been a prevailing notion that testosterone is bad. But we found the opposite in men," said senior study author Dr. Abhinav Diwan. He's professor of medicine, cell biology and physiology at Washington Univer...
Men who use anabolic steroids may be doing serious damage to their testicular function, new research warns.
And the damage may last long after they stop.
Illegal use of the drugs is not uncommon among athletes seeking to increase muscle size and strength and look more muscular, according to study lead author Dr. Jon Rasmussen, a postdoctoral scientist at the University Hospital of C...
Testosterone levels tend to fall in older men, but a new study shows that exercise -- and not supplemental testosterone -- is the way to rejuvenate the aging male heart.
Australian researchers found that without exercise, testosterone replacement therapy offered patients no improvement at all in cardiovascular health. But exercise alone -- absent any testosterone supplementation -- di...
Hormone therapy can be a lifesaver for men with prostate cancer, but it also appears to put some at increased risk of heart problems, a new study reports.
Long-term androgen deprivation therapy (ADT) increased the risk of heart-related death nearly fourfold in a group of prostate cancer patients, and also caused their heart fitness to decrease, researchers found.
Testosterone therapy ads promise to help aging men recapture their vitality, decrease body fat and enhance libido. But hormone treatments – while medically necessary for some men – aren't meant to be a fountain of youth, and experts warn more research is needed to determine if such therapy could boost heart disease risks.
Testosterone levels naturally decline in most men as ...
A testosterone-lowering drug can reduce male pedophiles' risk of sexually abusing children, according to a new Swedish study.
The drug, called degarelix, is used to treat prostate cancer and turns off production of testosterone. It's given by injection every three months and can lower testosterone levels within hours, according to researchers.
Exercise benefits prostate cancer patients who undergo hormone-reducing therapy, a small study suggests.
The treatment -- called androgen suppression therapy or androgen deprivation therapy (ADT) -- uses drugs or surgery to reduce the level of androgen hormones, which prostate cancer cells typically require to multiply.
"The problem is ADT has several side effects, including...
Listen up, guys: A healthy diet is good for your brain and heart, and also your sperm, new research suggests.
In a study of more than 2,900 Danish men, median age 19, those whose diet was rich in fish, chicken, vegetables, fruit and water had higher sperm counts than those who ate a "Western" diet rich in pizza, French fries, processed and red meats, snacks, refined grains, sugary be...
High levels of the sex hormone testosterone may trigger different health problems in men and women, a new study reveals.
In women, testosterone may increase the risk for type 2 diabetes, while in men it lowers that risk. But high levels of testosterone increase the risk for breast and endometrial cancer in women and prostate cancer in men, the researchers reported.
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 their component parts.
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 identify the cause.
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...
