Did you know? “Throwing like a girl” isn’t biology. Fausto-Sterling found that infants who start ball play earlier (often boys) practice from stable positions and throw farther sooner. Timing and practice, not sex, shape throwing skill. #SABV #OSSD #sexdifferences

Throwing like a girl: a critique of past approaches and an illustrated proposal for a path forward - Biology of Sex Differences
Background The phrase “Throwing like a girl” persists in popular culture and in scientific research as a trope about biological differences between males and females. In this review/theoretical paper ...

Did you know female brains have stronger norepinephrine projections from locus coeruleus to prefrontal cortex? BUT prefrontal neurons are less sensitive to signaling than in males! This study found sex differences in this stress and decision-making circuitry. #sabv #ossd #sexdifferences #humanhealth
Sex differences in noradrenergic regulation of the medial prefrontal cortex in mice - Biology of Sex Differences
Background Norepinephrine (noradrenaline; NE) is a stress signal released from the locus coeruleus (LC) into the prefrontal cortex (PFC) to govern arousal, attention, and cognition. The LC is sexually...

A mother's diet can leave lasting epigenetic fingerprints on her offspring's liver, altering how genes are expressed, long after the young eat healthy again. These changes can disrupt metabolism sex-specifically, potentially raising lifelong risk for fatty liver disease. #sabv #ossd #sexdifferences
Establishment of sex-specific liver transcriptomes and H3K9me3 profiles during sexual maturity: the impact of maternal obesity - Biology of Sex Differences
Background The escalating prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is closely linked to rising obesity rates. Maternal obesity (MO) is associated with increased s...

Giving female rats testosterone at male-like levels helped them bounce back faster after surgery, but it didn't actually make them experience less pain. Testosterone boosted recovery, not pain resistance! #sabv #ossd #sexdifferences #humanhealth www.sciencedirect.com/science/arti...
Impact of continuous testosterone exposure on reproductive physiology, activity, and pain-related behavior in young adult female rats
Testosterone may reduce pain in cisgender women and transgender men. Rodents can provide a useful model for investigating physiological effects of hor…
