Testosterone is a steroid hormone from the androgen group. In mammals, testosterone is primarily secreted in the testes of males and the ovaries of females, although small amounts are also secreted by the adrenal glands
Testosterone Physiological Effects
Testosterone is the principle male sex hormone and is responsible for reproductive growth and development in male vertebrates.
A chemical used in hydraulic fracturing, commonly called fracking, has the potential to interfere with reproductive hormones in men, according to research accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
Researchers say they have found a viable new therapeutic strategy for estrogen receptor-positive (ER+) breast cancer, even cancers that are resistant to current standard of care treatments.
Men with erectile dysfunction have a higher risk of death, regardless of their testosterone levels, suggests a study accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting, and publication in a special supplemental section of the Journal of the Endocrine Society.
Scientists may have discovered a new therapeutic approach to treat ER+ breast cancer using androgen receptor-stimulating drugs.
A study has found that fracking chemicals can interfere with male sex hormones and possibly cause adverse health effects.
Mothers do know best – or at least their noses do, according to a new study published in the journal Frontiers in Psychology in March 2020. Of course, mothers and others love smelling the sweet smell of a healthy, clean baby. However, more than just the pleasure of that body smell, complex nose-brain interactions seem to be telling mothers more about what stage of development the child is at, according to these researchers.
Melbourne researchers have uncovered important differences between the male and female immune system which may explain why men are more susceptible to obesity and metabolism-related associated diseases, such as heart disease, stroke and diabetes.
A new study published in the journal JAMA Network Open in February 2020 reports that Danish men who followed a healthy diet had the highest total sperm counts, and a better hormonal profile concerning hormonal regulators of fertility, compared to those on a Western or other less healthy types of diet.
Menopause- that time in every woman's life when the ovaries no longer release an egg each month and menstruation ceases forever- is a rare thing among Earth's infinitely varied creatures.
Nutrition researcher and New York Times bestselling author Neal Barnard, MD, demonstrates how foods affect our hormones--and our health--in his new book, Your Body in Balance.
Testosterone is a steroid hormone that triggers the development of male secondary sex characteristics. Though found mainly in men, the ovaries in women release small amounts of testosterone. When combined with estrogen, testosterone aids in the growth and repair of a woman's reproductive tissues.
A new study on the age of initial breast development as the first sign of puberty in girls shows that over the last 40 years, this has come down by an average of 3 months per decade. The study is published in the journal Pediatrics.
A team of researchers in the University of Tennessee Health Science Center's College of Medicine has been awarded a $1.98 million grant from the National Institute of Diabetes and Digestive and Kidney Disease, a division of the National Institutes of Health, for a novel approach to studying diabetes.
Transgender teens have a higher risk of having suicidal ideations, reports the U.S. Centers for Disease Control and Prevention (CDC). A new study suggests that having access to puberty blockers can significantly reduce the risk of suicide and other mental health issues.
Teens with obesity and polycystic ovary syndrome have more "unhealthy" gut bacteria suggesting the microbiome may play a role in the disorder, according to new research published in the Endocrine Society's Journal of Clinical Endocrinology & Metabolism.
A large Danish study has shown that fish oil supplements taken by healthy men of the reproductive age could help improve their testicular function as is evidenced by their semen quality and reproductive hormone levels. The study led by researcher Tina Kodd Jensen, titled, “Associations of Fish Oil Supplement Use With Testicular Function in Young Men,” was published this week in the latest issue of the JAMA.
For the many men diagnosed with testosterone deficiency, losing weight can help increase testosterone levels.
In the first-ever genome-scale analysis of the puberty process in humans, researchers at Huntsman Cancer Institute at the University of Utah outline distinct and critical changes to stem cells in males during adolescence.
When a non-scientist tries to imagine a scientist, the image that often arises is one of a somewhat remote, rather idealistic genius sitting alone in their room or laboratory and somehow discovering the most amazing things without every having contact with the 'normal' world.
A diet low in fat and high in egg whites could be the key to boosting male fertility according to a new pilot study.
