Animal and plant proteins show different associations with testosterone levels in men

A new study from the University of Eastern Finland found that higher animal protein intake is associated with lower blood testosterone levels, while higher plant protein intake is linked to higher levels. The study included 2,546 men aged 42–60 years and living in eastern Finland, and found that dairy protein intake was associated with...

A new scale for reproductive aging in Chinese women based on ultra-sensitive AMH testing

A new scale for reproductive aging in Chinese women has been developed based on ultra-sensitive AMH testing. The scale provides age-specific percentiles for AMH levels in women aged 35-55, enabling earlier identification of women at risk of low ovarian reserve and better management of perimenopausal symptoms.

Stress hormone timing creates a different kind of obesity

A new preclinical study found that glucocorticoid-rhythm disruption concentrates insulin resistance in skeletal muscle while preserving key insulin responses in fat tissue and liver, leading to a different type of obesity. This allows fat tissue to continue storing lipids, while the liver remains largely protected from fat accumulation.

Students who view more social media use more products that often harbor hormone-disrupting ingredients

A Rutgers study reveals that high school students who engage with beauty-related content on social media use more personal care products containing hormone-disrupting chemicals. The study found a significant correlation between time spent on social media and increased product usage, with girls reporting higher median daily product use.

Hidden hormone–habitat relationship revealed in reef fish

Researchers discovered a strong link between environmental variation and thyroid hormone signaling in reef fish, enabling them to adapt to changing habitats. The study found that habitat impacts development by altering gene expression and metabolic profiles, giving animals more flexibility when their environments change.

Study links birth control pills to more binge eating

A new study found that women taking hormone-containing birth control pills experienced higher rates of binge-related eating compared to those taking hormone-free pills. The research, published in JAMA Network Open, suggests that the hormones in birth control pills may contribute to increased emotional eating.

Improving protein folding may lead to new diabetes treatments

Researchers at Sanford Burnham Prebys Medical Discovery Institute found that enhancing protein-folding processes can help prevent harm to insulin-producing cells. The study revealed the importance of a chaperone protein called binding immunoglobulin protein and its cochaperone protein p58 IPK in maintaining proper proinsulin folding.

Cannabis use does not lower testosterone

A new study by UNIGE and SCAHT reveals that cannabis use is associated with an increase in testosterone levels, particularly in the testes. However, this increase does not appear to have a direct link to fertility, and further research is needed to determine potential long-term effects.
