What you may not know is that countless variations, or differences, in genetic makeup that occur in a large portion of the population also have an impact, albeit quite small, on the risk of developing cancer and other diseases. One of the many outgrowths of the Human Genome Project is to identify some of these variations to see what kind of effect they have on health as a way to better understand how and why cancer develops, as well as to help direct prevention, early detection, and treatment strategies. This study, reported at the annual meeting of the American Association for Cancer Research, is a prime example of how a very common genetic variation may lead to a slightly increased cancer risk. At a press conference, expert Christine B. Ambrosone, PhD, said that the field of molecular epidemiology, which involves looking at how genetic differences affect health, is really starting to get off the ground. This study is one of several groundbreaking findings in this area. Ambrosone is a cancer epidemiologist at the Derald H. Ruttenberg Cancer Center of Mount Sinai School of Medicine in New York. She was not involved in the study. Cancer researchers have found that girls who start their first period or start puberty at a relatively early age have a higher risk for breast cancer than girls who develop later. This suggests that hormones play a role in the development of breast cancer, begging the questions, which hormones are involved and how do they impact on cancer risk? The hormone estrogen is most abundant in women and associated with the development of ‘female’ characteristics, like breasts. Testosterone, on the other hand, is seen in its highest proportions in men and is associated with ‘male’ characteristics, like muscle development and body hair. Both hormones, however, are found to some degree in both men and women. Until recently, it was assumed that estrogen is a key player in puberty in young girls, but this new research points the finger at testosterone. Does that mean that testosterone levels affect cancer risk?
Men need ‘female’ hormone for sex drive, fat control: study

All rights reserved. Low levels of testosterone are common with age, Saad says, occurring in about 18% of 70-year-olds. Low levels of testosterone, he says, are associated with the metabolic syndrome — a cluster of risk factors such as abnormal cholesterol and high blood pressure that boost risk of heart disease, stroke, and type 2 diabetes as well as other risks to health. In the studies, Saad and his colleagues found that testosterone replacement therapy reduced the metabolic syndrome risk factors and did so in a similar way in all the age ranges studied.
Testosterone, Male Sex Hormone, Also Makes Guys Honest
Hormone Replacement Therapy Delays Male Aging Modern science and research have found that hormone therapy delays male aging process, and treats male hormonal imbalance. One hormone replacement therapy makes use of the male steroid hormone “DHEA” to slow down bone loss, improve skin health, and enhance sexual drive in old men. A study on DHEA reported that DHEA hormone therapy could improve memory and mood, and levels of the “stress” hormone called cortisol. (“DHEA,” 2009 University of Maryland Medical Center) Mass-produced synthetic hormones were once popular with the mainstream medicine. Due to the number of experts that argued the possible devastating side effects of this type of treatment, the method, though useful to an extent, did not progress. After a short while, science introduced the Bioidentical hormones that mimic the molecular structure of the hormones created by the human body. “Bioidentical hormone medications contain hormones that are an exact chemical match to those made naturally by humans,” says Manson, Chief of Preventive Medicine at Brigham and Women’s Hospital in Boston. (“Oprah and Bioidentical Hormones: FAQ,” by Miranda Hitti, WebMD Health News, Jan. 15, 2009) Bioidentical hormones, which are by-product of plant oils, can help men who have a hard time battling daily stress, depressed moods, and poor erections. Bioidentical hormone therapy replaces the hormones that the body had lost and needs back to function well. Natural Bioidentical Hormones Help Men Age Gracefully When hormones start to decline, no one can stop the degeneration, but something can slow down the progress. Bioidentical hormone therapy is all about life enhancement, extension and preservation. Ideally, a mans body must be equipped and programmed for balance and well-being. Men experiencing physical decline can find relief with hormone therapy to stabilize their conditions and prevent diminishing sex drive, weight gain, and mood swings. Bioidentical hormone therapy is a custom-made treatment based on the needs of a patient.
Hormone Replacement for Men: Pros, Cons
11, 2013 at 5:19 PM ET Video: Dr. Joel Finkelstein, an endocrinologist at Harvard Medical School and the lead author of a new study, talks about the effects of declining estrogen in men. Estrogen, the female hormone, is a lot more important to men than even many doctors think, according to a surprising new study published Wednesday in the New England Journal of Medicine. Researchers at Massachusetts General Hospital in Boston found that its actually a lack of estrogen thats most responsible for the accumulation of body fat plaguing men with low testosterone levels, raising their risks of cardiovascular disease and diabetes. Low estrogen is also a big contributor to the sexual dysfunction and low libido usually blamed solely on low testosterone. The research could change the way doctors prescribe hormones for men, experts suggest. Its a blockbuster, a mind bender for the general public and many scientists, Brad Anawalt, an endocrinologist and vice chair of the Department of Medicine at the University of Washington, who was not involved with the study, told NBC News. Men make about 80 percent of their estrogen through the conversion of testosterone into an estrogen by an enzyme called aromatase. So when testosterone drops, so does estrogen. Low testosterone itself is linked to declines in lean muscle mass, muscle size, and strength, the study found.
‘Male’ Hormone Tied to Early Puberty in Girls
They would be rewarded financially based on the numbers — one Euro for 1; two Euros for 2, and so forth, except for the number 6. They would get nothing for a number 6. No one else was present. Each man was alone; absolutely no one would know if he was cheating. Even the researchers were unable to monitor the activity. So how did they learn that participants were less likely to lie if given testosterone? The answer is in the details.
