Testosterone

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

Serum testosterone status recovery an accurate predictor of survival in male COVID-19 patients

In a study available on the medRxiv* the preprint server, researchers from Spain showed that testosterone trajectories are very accurate individual predictors of survival in male patients with COVID-19. To better understand the relationship between testosterone levels and disease severity, they studied a group of male and female COVID-19 patients assessing their serum and blood biomarkers in association with outcome of disease.

Songbird plumage and testosterone levels are altered by wildfire

Fire can put a tropical songbird's sex life on ice. Following habitat-destroying wildfires in Australia, researchers found that many male red-backed fairywrens failed to molt into their red-and-black ornamental plumage, making them less attractive to potential mates. They also had lowered circulating testosterone, which has been associated with their showy feathers.

Study shows that breast cancer can be prevented with better contraception choices

Hormonal contraceptives, e.g. the pill, the patch, and the vaginal ring, contain synthetic hormones that prevent pregnancy by either stopping ovulation, changing the cervical mucus to stop sperm from passing through the cervix and finding an egg, or changing the womb's lining to prevent a fertilized egg from being implanted in it.

Severe COVID-19 linked to genetic clotting predisposition

Thus, the need to stratify the risk of severe or critical disease in patients presenting with SARS-CoV-2 infection remains a crying necessity. A new preprint research paper posted to the medRxiv server discusses the relationship between severe disease and pre-existing susceptibility to clots and other diseases of the cardiovascular system.

Previously overlooked hormone plays critical role in the development of endometriosis

Endometriosis, a disease found in up to 10 per cent of women, has been enigmatic since it was first described. A new theory developed by researchers at Simon Fraser University suggests a previously overlooked hormone -- testosterone -- has a critical role in its development.

Combination of BMI and body shape predictor can help determine the risk of obesity-related cancers

New research being presented at The European Congress on Obesity (ECO) held online this year, suggests that a measure of body shape should be used alongside body mass index (BMI) to help determine the risk of obesity-related cancers.

Pro-inflammatory diet may be associated with increased risk of testosterone deficiency in men

Consuming a diet high in pro-inflammatory foods - including foods that contain refined carbohydrates and sugar as well as polyunsaturated fats - may be associated with increased odds of developing testosterone deficiency among men, suggests a study in The Journal of Urology, Official Journal of the American Urological Association.

Two extremes of female sexual behavior may be controlled by the same brain region

In many species, including humans and mice, the fluctuating levels of the hormones progesterone and estrogen determine whether the female is fertile or not. And in the case of mice, whether she's sexually receptive or not.
