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...

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...

The World Health Organization said Wednesday that Bisphenol-A (BPA) is mostly eliminated through urination and does not accumulate in the body. A panel of 30 experts from Canada, the U.S. and Europe met in Ottawa to determine that the amounts of the chemical used in plastic food containers and packaging were not harmful to human health.  The levels of BPA measured in urine were equivalent to ingested amounts of the chemical. Levels of the chemical were "very low, indicating that BPA...

A break in the two chromosomes has given scientists a break in finding a new gene involved in puberty, Medical College of Georgia researchers report. It's also helped clear up why some patients with delayed puberty have no sense of smell, said Dr. Lawrence C. Layman, chief of the MCG Section of Reproductive Endocrinology, Infertility and Genetics. The WRD11 gene interacts with a transcription factor that appears to be involved in development of gonadotropin releasing hormones that enable...

(Ivanhoe Newswire) "“ Look out moms! Girls who live in a home without a father are more likely to hit puberty at an earlier age. The study found that in a home where the biological father was absent, the daughter developed breasts and pubic hair quicker. This is only true for girls in high-income homes. "The age at which girls are reaching puberty has been trending downward in recent decades, but much of the attention has focused on increased body weight as the primary culprit," the...

Girls in homes without a biological father are more likely to hit puberty at an earlier age, according to a new study led by researchers at the University of California, Berkeley's School of Public Health. The findings, to be published Sept. 17 in the Journal of Adolescent Health, found that the absence of a biologically related father in the home predicted earlier breast and pubic hair development, but only for girls in higher income households. The findings held even after the girls' weight...

Differences between the sexes affected by environment during first six months of life It seems the old nature versus nurture debate can't be won. But a new Northwestern University study of men in the Philippines makes a strong case for nurture's role in male to female differences -- suggesting that rapid weight gain in the first six months of life predicts earlier puberty for boys. Males who experienced rapid growth as babies -- an indication that they were not nutritionally stressed -- also...

Researchers from Mount Sinai School of Medicine have found that bisphenol A (BPA) released from some plastic resins used in pediatric dentistry is detectable in the saliva after placement in children's mouths. BPA is a widely used synthetic chemical that has been associated with changes in behavior, prostate and urinary tract development, and early onset of puberty. The findings are published in the current issue of Pediatrics. Reins containing BPA are commonly used in preventive and...

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...
