Overweight does not decrease sperm production

A new study by The Endocrine Society found that overweight men are not more likely to be infertile, contradicting previous research on obese women. Greater body weight was linked to lower testosterone levels in some participants, but impaired sperm production remains the primary cause of infertility in men.

Current screening test for prediabetes in children misses the diagnosis too often

A new Canadian study found that the standard screening test for high blood sugar in children with risk factors misses nearly 3 times fewer cases of prediabetes than a longer test. The glucose stress test identified more cases of both prediabetes and metabolic syndrome. Early detection is crucial, as it can prevent or delay diabetes.

Estrogen therapy helps or hurts the brain depending on reproductive status

A new animal study suggests that estrogen treatment is not toxic per se, but its effects on the brain depend on an individual's reproductive age. In rats, estrogen therapy reduced brain damage when given before menopause, but increased it after, highlighting a narrow window of time for neuroprotective benefits.
