Later puberty results in lower bone mass and increases risk of fracture A team of researchers led by Vicente Gilsanz, MD, PhD, director of Clinical Imaging at The Saban Research Institute of Children's Hospital Los Angeles, determined that the onset of puberty was the primary influence on adult bone mineral density, or bone strength. Length of puberty did not affect bone density. Reduced bone mineral density leads to osteoporosis, resulting in bones becoming increasingly brittle and at risk...

CHADDS FORD, Pa., Dec. 29, 2010 /PRNewswire-FirstCall/ -- Endo Pharmaceuticals (Nasdaq: ENDP) today announced that the U.S. Food and Drug Administration (FDA) has approved FORTESTA Gel for the treatment of low testosterone, or 'Low T,' also known as hypogonadism. Symptoms associated with Low T include erectile dysfunction and decreased sexual desire, fatigue and loss of energy, mood depression, regression of secondary sexual characteristics and osteoporosis. Low T is a condition that has...

UT Southwestern Medical Center researchers have pinpointed a tiny site in the brain where the hormone leptin may help trigger the onset of puberty. The findings in mice indicate that a site within the hypothalamus called the ventral premammillary nucleus, or PMV, is the target where the hormone leptin effectively kick starts puberty in females. Researchers have known that puberty starts when individuals have enough energy stores or fat to meet the demands of reproduction, and that leptin...

The timing of the onset of puberty is linked to levels of nutrition: later onset is associated with malnutrition, while earlier onset is linked to childhood obesity. A team of researchers, led by Carol Elias, at the University of Texas Southwestern Medical Center, Dallas, has now generated data in mice that run counter to current thinking about the molecular pathway by which nutrition status affects the onset of puberty. Further, the team defines a new regulatory pathway for the process,...

According to a study published Wednesday, cash register receipts and paper money have been found to contain high levels of bisphenol A (BPA), a chemical linked to cancer, obesity and early puberty. Researchers from U.S. non-profit groups Safer Chemicals, Safer Families and the Washington Toxics Coalition tested receipts made from thermal paper that they collected from 22 popular retailers and cafes. "Since BPA in thermal paper is present in a powdery film, we suspected it could easily...

University of Minnesota School of Public Health researcher Ellen Demerath, Ph.D., is among an international group of researchers that has identified 30 new genes responsible for determining the age of sexual maturation in women. Many of these genes are also known to influence body fatness, obesity, and energy metabolism. Prior to the multi-institutional study, only four genes had been identified as contributing to the process. The findings, which were reported in Nature Genetics, help to...

A hormone responsible for the onset of puberty can end up stuck in the wrong part of the body if the nerve pathways responsible for its transport to the brain fail to develop properly, according to research funded by the Biotechnology and Biological Sciences Research Council (BBSRC). By tracking how nerve cells responsible for regulating sexual reproduction in mice find their way from their birth place in the foetal nose to their site of action in the adult brain, scientists from University...

INDIANAPOLIS, Ind. and MELBOURNE, Australia, Nov. 23, 2010 /PRNewswire-FirstCall/ -- Eli Lilly and Company (NYSE: LLY) and Acrux (ASX: ACR) announced that the U.S. Food and Drug Administration (FDA) has approved Axiron® (testosterone) topical solution CIII for replacement therapy in men for certain conditions associated with a deficiency or absence of testosterone. Safety and efficacy of Axiron in males younger than 18 years of age have not been established. To view the...

Scientists have discovered 30 new genes that control the age of sexual maturation in women. Notably, many of these genes also act on body weight regulation or biological pathways related to fat metabolism. The study, which appears in Nature Genetics, was a collaborative effort by the international ReproGen consortium, which included 175 scientists from 104 worldwide institutions, including Boston University School of Medicine (BUSM) and Boston University School of Public Health. Menarche, the...

With the help of babies and more than 5,000 of their diapers, Emory University researchers have developed an accurate, noninvasive method to determine estrogen levels in infants. The method, previously used in nonhuman primates, will allow researchers to learn more about the association between estrogen levels in human infants and their long-term reproductive development as well as the development of sex-specific behaviors, such as toy preference or cognitive differences. What's more, the...

Testicles
2013-03-04 15:03:13

The testicles are the male reproductive organs that serve as a part of both the nervous and reproductive systems, acting as the ovaries’ counterpart. The testicles work to produce sperm and introduce chemicals such as testosterone. Formation and Orientation There are normally two testicles in the average male anatomy. These can be found in the protective sack called the scrotum. Two phases mark the growth of the testicles. During the embryonic stage, there is a possibility of this...
