Men with low levels of the male sex hormone testosterone need not fear that testosterone replacement therapy will increase their risk of prostate cancer.This is the finding of an analysis of more than a quarter-million medical records of mostly white men in Sweden, research led by investigators at NYU Langone Medical Center and its Laura and Isaac Perlmutter Cancer Center. At DoveMed, we believe that reliable healthcare information helps you make better choices for yourself and your loved ones. In the hypothalamus, androgens bind to the androgen receptor (AR) to stimulate production of luteinizing hormone (LH)-releasing hormone (LHRH). The length of time of testosterone treatment, as well as number of injections, did not have any effect on prostate cancer after men had been diagnosed. Prostate cancer generally is a slow-growing disease, however researchers mounted the study based on concerns by doctors and a lack of research in the area for patients who'd been on testosterone therapy for more than a year. The researchers used data collected by the National Cancer Institute as part of the SEER study on 52,579 men diagnosed with prostate cancer between 2001 and 2006, and had been enrolled in Medicare for at least five years before being diagnosed. Of the men with prostate cancer, 579 had used testosterone in the five years before their diagnosis.
SAN FRANCISCO, June 8 (UPI) -- Treating high cholesterol in young adults could help prevent heart attacks and heart disease later in life, a recent study suggests.
BOSTON, June 8 (UPI) -- Creating a carbon standard for power plants in the United States could save the country billions in both energy and health costs, according to a recent study. BALTIMORE, June 7 (UPI) -- Despite the media framing people who commit violent crimes as having mental illnesses, people diagnosed with the conditions rarely commit violent acts. Someday, dialysis patients might free themselves of clunky machines, moving about with a "wearable artificial kidney" instead. Researchers have found bacteria in women's ovaries and fallopian tubes -- locations previously believed to be sterile.

JACKSONVILLE, Fla., June 7 (UPI) -- Four patients with fecal incontinence received an implantable device that mimics the anal sphincter, the first to receive it since FDA approval in 2015.
General anesthesia doesn't seem to harm young children's mental development, new research concludes.
Black breast cancer survivors less likely than other women to get follow-up genetic screening and surgeries that can prevent a return of cancer, research finds. Young children with a rare cancer of the nervous system might have a better chance of survival if they receive two stem cell transplants, a new study reports.
With a history of reliable reporting dating back to 1907, today's UPI is a credible source for the most important stories of the day, continually updatedA A - a one-stop site for U.S. Sex hormones, such as testosterone and adrenal androgens, act on prostate epithelium after conversion to dihydrotestosterone (DHT).
DoveMed urges their users to consult a qualified healthcare professional for diagnosis and answers to their personal medical questions. 5 (UPI) -- Researchers found in a recent study that testosterone therapy for over a five-year period did not increase the risk for aggressive prostate cancer, nor did the number of injections increase the risk of developing the disease.
They found that neither the length of time men had been receiving testosterone therapy nor the number of injections they'd received increased the risk for the disease. UPI also provides insightful reports on key topics of geopolitical importance, including energy and security. It became known as UPI after a merger with the International News Service in 1958, which was founded in 1909 by William Randolph Hearst. Its popularity is a consequence, experts say, of an aging "boomer" population and heavy drug industry marketing, and has come about despite its unknown, long-term health risks.

LH that is released by the pituitary binds to LH receptors (LH-R) in the testes, inducing production of testosterone, which is synthesized from cholesterol.
According to some surveys, use of testosterone therapy has more than tripled since 2001, with more than 2 percent of American men in their 40s and nearly 4 percent of men in their 60s taking it. Testosterone enters prostate cells, where it is converted to dihydrotestosterone (DHT) by the enzyme 5-reductase. Testosterone levels drop naturally by about 1 percent per year in men past their 30s.Specifically, the current study found that 38,570 of the men whose records were examined developed prostate cancer between 2009 and 2012.
DHT binds tightly to AR, enters the cytoplasm, and the complex translocates to the nucleus where it activates transcription of genes that regulate cell growth and survival. Of these men, 284 had prescriptions for testosterone replacement therapy before they were diagnosed with prostate cancer.
Increased testosterone levels can also decrease LHRH and LH production through negative-feedback loops, thereby maintaining serum testosterone at physiological levels. Their records were compared with 192,838 men who did not develop prostate cancer, of whom 1,378 had used testosterone therapy.Researchers noted that while their initial analysis showed an uptick (of 35 percent) in prostate cancer in men shortly after starting therapy, the increase was only in prostate cancers that were at low risk of spreading and was likely a result from more doctor visits and biopsies performed early on.
