Higher levels of the hunger hormone ghrelin predict a greater preference for smaller, immediate financial rewards over larger, delayed financial rewards. Read More
Sex hormones play a crucial role in brain health, especially when it comes to the sex-based risk factors associated with dementia. Read More
Exercise promotes the hypothalamus to release MOTS-c. Mitochondrial encoded MOTS-c interacts with the nuclear genome and regulates both cell metabolism and the stress response. Read More
Menopausal women who frequently sunbathe have increased levels of gonadotropins and lower levels of estrogen than their peers who are not active sun worshipers. Low estrogen levels and higher levels of other hormones increase the risk for a number of health problems, including Alzheimer's disease. 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
Oral contraceptive use is associated with blunted stress response and brain activity differences during working memory tasks in women who started using birth control during puberty. Early adulthood exposure to oral contraceptives was linked to significant structural changes in brain areas associated with memory and emotional processing. Read More
Lower levels of vasopressin were present in the cerebrospinal fluid of infants who later went on to be diagnosed with autism. Read More
Using magnetic nanoparticles, researchers were able to stimulate the adrenal glands of rodents and control the release of stress-related hormones. The approach could be applied to humans to treat hormone-related disorders. Read More
Study tests the good genes ovulation shift hypothesis, which states women's preferences for certain male behaviors differ throughout their ovulation cycle. Researchers found no evidence that a woman's preference changes across the ovulation cycle. However, women tend to perceive men as slightly more attractive when fertile than during other cycle phases. Read More
Researchers report the hormone prolactin, more commonly associated with lactation in new mothers, may underlie why women are more vulnerable to developing functional pain syndromes than men. Read More
A new study confirms the link between menstruation and worsening of psychosis symptoms in women with mental health disorders. Researchers found psychiatric admissions for women were one-and-a-half times higher during the time of menstruation. Read More
Estrogens were significantly elevated in fetuses that later went on to develop autism. Higher levels of prenatal estrogens were more predictive of ASD than higher levels of prenatal androgens. The study supports a twenty-year-old theory that increased prenatal sex steroid hormones are a potential cause of autism spectrum disorder. Read More
