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.
Congenital adrenal hyperplasia (CAH) is a disorder that affects the adrenal gland's ability to release hormones that regulate the body's response to stress and illness.
Rank in social hierarchy is a condition not solely claimed by humans. In the animal kingdom, male peacocks exhibit brightly colored plumes to illustrate dominance, and underwater, male fish show pops of bright colors to do the same.
A new discovery about how the body transports dexamethasone, a drug that can increase the survival chances of patients with severe COVID-19, suggests diabetes and other factors may reduce its potentially lifesaving effectiveness.
The Mediterranean diet may be investigated as a possible treatment for polycystic ovary syndrome after mice with PCOS-like features of the condition were found to benefit from a similar diet.
The National Institutes of Health has awarded $1.6 million to researchers at the George Washington University School of Medicine and Health Sciences for research on hormonal control of HIV latency.
Since the beginning of the COVID-19 pandemic, researchers have noted that women are generally less severely affected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This has led to the exploration into estrogen and androgens' role in the hyperinflammatory clinical phenotypes of COVID-19. A recent study published on the preprint server bioRxiv shows that drugs targeting androgens and TMPRSS2 inhibitors may potentially combat the pandemic.
For the first time, data from a study with patients hospitalized due to COVID-19 suggest that the disease might deteriorate men's testosterone levels.
Exposure to hydraulic fracturing fluid in drinking water has been shown to increase the risk of respiratory problems, premature births, congenital heart defects, and other medical problems. But not all wells are created equal.
Doctors will soon be able to use fat to diagnose musculoskeletal disease within seconds and predict the risk of falls and fractures in older people, thanks to a world-leading tool developed by Melbourne researchers.
The locus of male sexual desire has been uncovered in specific regions of brain tissue where a key gene named aromatase is present, reports a new Northwestern Medicine study in mice.
Now, a new study by a research team from Yale University, USA, Edith Cowan University, Australia, and the University of Strathclyde, Scotland, and published on the preprint server medRxiv in September 2020 shows that kynurenic acid is the underlying factor which is responsible for these differences.
Patients with autoimmune inflammation of their thyroid may be at greater risk of developing anxiety, according to a study being presented at e-ECE 2020.
Research conducted by the University of Valencia (UV) and the Jaume I University of Castellón (UJI), among other institutions, has found alterations to the structure of the brain's nonapeptidergic systems, social behavior and the production of pheromones, traits that reveal sexual dimorphism, in male mice with a lack of the Mecp2 gene.
A new study published on the preprint server medRxiv in August 2020 shows that the risk of infection is high for pre-menopausal women but the risk of death is much higher for men in the same age group and throws light on the protective nature of estradiol therapy in post-menopausal women.
Results from an international clinical trial found that men with advanced prostate cancer who have mutated BRCA1/BRCA2 genes can be treated successfully with a targeted therapy known as rucaparib, resulting in recent FDA approval.
Running is one of the most popular forms of exercise, enjoyed by a broad range of age groups and skill levels. More women are running recreationally compared to men; specifically 54% of runners are female as indicated by a 2018 National Runner Survey.
New insight on differences in the brains of men and women with autism has been published today in the open-access journal eLife.
Almost from the beginning, scientists have been struck by the disproportionately higher numbers of men and older adults who have developed severe COVID-19 disease compared to younger individuals and women. Prior research has shown that in 37 of the 38 countries from which sex-stratified data was available, males were at a higher risk of death. Also, post-menopausal women are at increased risk of severe COVID-19. However, the biological underpinnings of this have been less visible.
News-Medical speaks to Dr. Robert M. Sargis about his research into whether medication is exposing us to hormone-disrupting chemicals.
In this interview, Dr. Andrea Dunaif talks to News-Medical about their genetic analysis study which suggests there are different subtypes of PCOS.
