Researchers uncover mechanism that initiates sexual organs maturation

Puberty is a period of extensive changes of body morphology and function. As much as we are familiar with these life-altering changes, relatively little is known about what sets the whole process in motion.

Boys with obesity enter puberty at earlier age, shows study

Girls are not the only ones who go through puberty early if they have obesity. Boys with obesity enter puberty at an earlier age than average, according to a study that will be presented Sunday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

A call for more comprehensive research models to study different aspects of puberty

Puberty is much more than just a time of biological overdrive, propelled by sexual maturation. Progress in developmental science has greatly broadened the perspective of this critical maturational milestone.

Researchers to examine how sexual trauma increases HIV risk in women

The link between sexual violence and HIV risk is well-known, extensively documented through behavioral research. But there is growing evidence that sexual trauma also poses a heightened biological risk for HIV infection, especially in adolescents and young women.

Onset of puberty depends on gap between parents' and child's height

Ben-Gurion University of the Negev researchers have found that the age puberty hits is based on the gap between the parents' and child's ultimate height, not genetics.

Study may have important implications for refining parenting during child's adolescence

The field of adolescent psychology is increasingly focused on parents, with researchers asking how mothers and fathers control themselves (and their rising anger) in difficult interactions with their children.

DDT exposure linked to increased breast cancer risk for all women through age 54

All women exposed to high levels of DDT are at increased risk for breast cancer through age 54, but the timing of cancer risk depends on when they were first exposed, according to a new study published today in the Journal of the National Cancer Institute.

Study of spermatogonial stem cells opens path for new strategies to treat male infertility

The production of sperm -- otherwise known as spermatogenesis -- generates more than 1,000 sperm per second in normal males.

Researchers identify regulatory mechanism underlying obesity

Obesity − as research in the past decade has shown − is first and foremost a brain disease. Researchers at Helmholtz Zentrum München, partners in the German Center for Diabetes Research, have now discovered a molecular switch that controls the function of satiety neurons and therefore body weight. The findings were published in the journal 'Nature Metabolism'.

Childhood body composition may play a role in future respiratory health

How well we breathe as adults may depend on the amount of fat mass and lean body mass, or muscle, we have as children, according to new research published online in the American Thoracic Society’s American Journal of Respiratory and Critical Care Medicine.

Youth with obsessive and compulsive symptoms more likely to experience psychopathology

Engaging in repetitive and ritualistic behaviors is part of typical child development. However, behaviors that develop into obsessive and compulsive symptoms may represent a red flag for serious psychiatric conditions.

Researchers identify genes that drive male-female brain differences, trigger initiation of puberty

Researchers have identified a group of genes that induces differences in the developing brains of male and female roundworms and triggers the initiation of puberty, a genetic pathway that may have the same function in controlling the timing of sual maturation in humans.

Paternal grandfather's access to food associated with grandson's mortality risk

A paternal grandfather's access to food during his childhood is associated with mortality risk, especially cancer mortality, in his grandson, shows a large three-generational study from Stockholm University. The reason might be epigenetic - that environmental exposures in one generation may influence health outcomes in following generations.
