Exercise Makes Female Rats Hungrier and Sustains Weight Gain

Study in rats reveals sex differences may play a key role in the effectiveness of exercise as an appetite regulator. Exercising female rats ate more than those who did not partake in physical activity. The same effect was not seen in males.

Greater Excitability in Social Brain Regions of Autistic Men Compared to Women

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.

Highly Reproducible Sex Differences in Aspects of Human Brain Anatomy

Analysis of over 2,000 brain scans revealed evidence of highly reproducible sex differences in the volume of different regions of the brain. On average, females had greater cortical volume in the medial and lateral prefrontal cortex, orbitofrontal cortex, superior temporal cortex, and lateral parietal cortex. Males had increased volume in the ventral temporal and occipital brain regions. Gene expression data suggest the potential role of sex chromosomes that contribute to the differences.

Females exhibit more intense subjective cannabis cravings than males

Researchers also found preliminary evidence that ovarian hormones may modulate the differential response in women and may be related to different levels of estrogen.

Breathing during exercise is harder for women than men

On average, women have to work harder to breathe during strenuous exercise than men. The findings not only shed light on how sex may affect exercise dynamics but also the differences in how men and women experience airway disorders, such as asthma and COPD.

Novel class of specific RNAs may explain increased depression susceptibility in females

Long non-coding RNAs (lncRNAs) are significantly altered in depression in both sex and brain site-specific manners. The LINC00473 gene is downregulated in the prefrontal cortex of depressed females, but not males. Findings reveal the role of LINC00473 in sex-specific depression and may explain why females are more vulnerable to depressive symptoms than males.

Slower Clearance of Coronavirus Infection May Explain Why Men Fare Worse Than Women

A new study seeks to explain why men infected by coronavirus generally show more severe symptoms and have an increased risk of death over women. Focusing on ACE2 receptors, researchers found the testes, along with the lungs and kidneys, were among areas of the body with the highest ACE2 expression. ACE2 could not be detected in ovarian tissue. The findings back up a previous study that reported male COVID-19 patients experienced impaired testicular function. This suggests the testes may be significantly affected when men develop coronavirus.

High fat diet impairs new neuron creation in female mice

Female mice exposed to a high-fat diet have limited hippocampal neurogenesis. The findings may explain why women are at higher risk of developing dementia than men.
