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.
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has caused over 9.263 million cases and taken more than 477,000 lives as of June 24, 2020 – just six months after the initial outbreak in Wuhan, China, was reported. The illness, called COVID-19 disease, caused by SARS-CoV-2 is a severe pneumonic illness, caused by the entry of the virus into the type II alveolar cells.
How do animals adapt their behavior during life in order to assure survival and reproduction? This is a question of great interest for behavioral biologists worldwide.
The preliminary results of a Phase I clinical trial conducted by researchers at the Yale Cancer Center have shown that ARV-110, an androgen receptor PROTAC protein degrader, demonstrates clinical evidence of anti-tumor responses in patients with metastatic castration-resistant prostate cancer (mCRPC) who have failed prior therapy.
A paper published in Psychotherapy and Psychosomatics, provides a careful analysis of the medical consequences of anabolic-androgenic steroid use in men.
A drug that lowers levels of the male hormone testosterone in the body reduces the risk of men with pedophilic disorder sexually abusing children, a study from Karolinska Institutet published today in the journal JAMA Psychiatry shows.
A postmortem exam of the brain remains the gold standard for diagnosing chronic traumatic encephalopathy, or CTE, the neurodegenerative brain disease believed to arise from repeated hits to the head.
Women with Polycystic Ovary Syndrome should consider adopting a mindful yoga practice to help ease symptoms and improve androgen levels. Researchers found a one-hour mindful yoga class, done three times a week, reduced testosterone levels by 29% over a three-month period.
Skoltech scientists and their colleagues proposed a way to simplify the search for traces of medicines, narcotic substances and sports doping drugs in human biological samples by performing two additional tests with the search domain reduced tenfold.
Physicians from Sapienza University in Rome have published promising results of a small prospective interventional trial using noninvasive pulsed electromagnetic field therapy (PEMF) to treat men suffering from benign prostatic hyperplasia.
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.
