In this new study, the researchers have designed a new protein which blocks the hormone receptors and consequently stops prostate cancer cells from growing in the laboratory. The therapy was successful even in circumstances that lead to the failure of conventional treatments.

The effects of gravity may explain the apparently paradoxical effects of testosterone in male pattern baldness, or androgenic alopecia (AGA), according to a special topic paper in Plastic and Reconstructive Surgery—Global Open®, the official open-access medical journal of the American Society of Plastic Surgeons (ASPS).

The team studied the effects of a class of drugs called TSPO ligands on male mice that were genetically engineered to develop Alzheimer’s disease, known as 3xTg-AD mice. Because a key mechanism of TSPO ligands is to increase production of steroid hormones, it was important to ensure that the mice had low levels of testosterone and related hormones before treatment. Younger mice were castrated while, in older mice, the decrease occurred as a normal consequence of aging.

Sporting events can bring a community together, such as when the Louisville Cardinals won the NCAA championship and University of Louisville campus was filled with camaraderie. They also can fuel bitter rivalries, such as the long-standing animosity between the St. Louis Cardinals and the Chicago Cubs. A new University of Missouri study has found that testosterone levels during group competition are modulated depending on the relationships among the competitors and may be related to the formation of alliances in warfare.

New findings led by Dr. Michael Lombardo, Prof. Simon Baron-Cohen and colleagues at the University of Cambridge indicate that testosterone levels early in fetal development influence later sensitivity of brain regions related to reward processing and affect an individual’s susceptibility to engage in behavior, that in extremes, are related to several neuropsychiatric conditions that asymmetrically affect one sex more than the other.

Researchers of the Max Planck Institute for Ornithology in Seewiesen have now discovered that in duetting African white-browed sparrow weavers, the solo song of dominant males is linked to elevated levels of testosterone. What is more, the male-typical solo song could be activated via testosterone treatment in female birds. The study thus shows a complex relationship between song behaviour and hormone concentration also in a tropical bird species.
