Researchers found that UVB phototherapy increases levels of romantic passion and aggression in both men and women. Exposure to sunlight affects the endocrine system's regulation of sexual hormones.
A comprehensive review of plant reproductive systems provides new perspectives on heterostyly, highlighting recent advances and unresolved questions. The study explores the ecology, evolution, genetics, and genomics of plant reproductive strategies, shedding light on their role in ecological interactions and evolutionary change.
Researchers at NIH reveal that COUP-TFII determines sex-specific reproductive system development in mice. Female mouse embryos without COUP-TFII display both male and female ducts, indicating the active removal of male reproductive systems.
A new study by UCLA researchers found that Bisphenol S (BPS) damages a woman's eggs at lower doses than BPA. The study exposed roundworms to various concentrations of BPA and/or BPS, revealing decreased fertility in those exposed to either chemical.
Two UConn projects, a light imaging system for rapid ovarian cancer detection and an artificial salivary gland for dry mouth relief, are developed with the help of the BioScience Pipeline Program. A bone scaffold system that can replace bone grafts is also being created.
New UCLA research demonstrates that BPS, a common replacement for BPA, speeds up embryonic development and disrupts the reproductive system. Exposure to low levels of BPA and BPS alters physiology in as quickly as 25 hours, leading to premature birth and disruption of reproductive endocrine brain cells.
A newly discovered mechanism in worms suggests that mothers sacrifice their health for future generations, fueling egg cell development with fats. This phenomenon raises the possibility of a similar trait in humans, potentially impacting reproductive success and lifespan.
A new study by WSU geneticist Patricia Hunt and colleagues reveals BPA can damage chromosomes, disrupt egg development, and increase the risk of miscarriages and birth defects in rhesus monkeys. The research bolsters earlier findings on reproductive effects in rodents and raises concerns about human exposure to this common chemical.
The new report updates the landmark STRAW system, providing a clearer understanding of reproductive aging in women from pre-menopause to the late postmenopausal period. The updated stages include significant revisions, offering more precise definitions and predictions for the onset of menopause.
A Kaiser Permanente study found that workers exposed to high levels of Bisphenol-A (BPA) in their jobs had a quadruple the risk of erectile dysfunction and seven times more risk of ejaculation difficulty. This is the first human study to measure the effects of BPA on the male reproductive system.
A cohort study of over 2,000 Air Force veterans found that dioxin exposure was associated with a lower incidence of benign prostate hyperplasia (BPH) and decreased testosterone levels. The study suggests a link between dioxin exposure and endocrine disturbances in the male reproductive system.
Researchers discovered a new brain hormone GnIH that directly inhibits the action of gonadotropin-releasing hormone (GnRH), stimulating the reproductive system. This finding suggests that GnIH plays a similar role in humans and other mammals, offering potential new treatments for infertility and precocious puberty.
A new mouse model reveals that early pregnancy loss is triggered by the immune system's interference with reproductive hormones, specifically progesterone. This finding may contribute to human infertility and recurrent pregnancy loss, providing a potential target for therapy.
A study by Ohio State University researchers found three genes associated with regulating thyroid hormones in the hypothalamus, which controls the hamster's reproductive cycle. The genes were active in hamsters kept in both long and short days, enabling them to respond to seasonal changes.
Researchers found that exposure to short days triggers immune system enhancements in mice, which last for approximately 20 weeks. The immune system returns to its non-enhanced status after 32 weeks, even if short days remain. Melatonin levels are believed to play a key role in this process.
A Dartmouth-VA study found that for-profit hospital ownership is associated with higher per capita Medicare spending and faster spending growth compared to non-profit hospitals. The analysis controlled for various factors that might influence health care costs.
