Hard wired neural circuits in mice that govern aggression are strengthened following victories in aggressive encounters. Synapses in the hypothalamus show signs of LTP following aggression training. Read More
A new study suggests COVID-19 may deplete testosterone levels in males. Findings reveal as testosterone decreased, the severity of coronavirus increased. Men who died from coronavirus infection had significantly lower mean testosterone than those who recovered. For those who were asymptomatic, 65.2% reported a loss in libido. Read More
Researchers have uncovered specific regions of brain tissue where aromatase is present, that drives male sexual desire. Aromatase converts testosterone into estrogen in the brain, driving male sexual activity. Read More
Males with autism have atypically enhanced excitation in the medial prefrontal cortex (mPFC). This area of the brain is associated with social cognition and self-reflection. Autistic women showed a more intact mPFC response, which was associated with a better ability to camouflage social difficulties in real-world settings. Read More
Degarelix, a drug that reduces testosterone levels, shows potential in the treatment of pedophilic disorder. Men with a history of child sexual abuse who took the drug had reduced overall sexual desire and decreased attraction toward children, with noticeable effects within two weeks. Read More
A circuit-specific gender difference in ventral hippocamps to nucleus accumbens (vHPC-NAc) neurons is dependent on testosterone and causes more susceptibility to stress in females. Read More
A new study challenges the existing theory that testosterone levels are linked to reduced cognitive empathy. Read More
Former NFL players who received a concussion while playing are more likely to report low testosterone and erectile dysfunction. Researchers speculate the reason could be damage to the pituitary gland caused by concussion may spark a cascade of hormonal changes. Read More
Contrary to popular belief, a new study reveals higher levels of testosterone may make people more sensitive to moral norms. Read More
A new study reveals how male sex steroids impact brain development. The findings could help shed light on behavioral developmental differences between males and females. Read More
Embedding a molecule called TRPM8 into the surface of some cells helps reduce aggression and sexual appetite in mice, a new study reports. Read More
Researchers report mice with epilepsy have alterations in neural pattern activity in an area of the brain that controls the reproductive endocrine system. Read More
