Researchers have now found a way to propagate primary human Sertoli cells in the laboratory -- the first step, say investigators, to developing an artificial human testicle for reproductive research. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body. San Francisco, CA (Vocus) October 25, 2010 After more than 30 years of unsuccessful efforts by numerous investigators,...

Scientists have developed a model that will enable them to investigate, for the first time, how human testes develop in baby boys while they are in the womb. Until now it has been impossible to study testicular development during pregnancy in humans and this discovery will enable researchers to understand the processes that can lead to the onset of testicular germ cell cancer (TGCC) in young adult life, and how factors, such as common environmental chemicals, might play a role. The research...

Adult circumcision has been proposed as a possible HIV prevention strategy for gay men, but a new study by the University of Pittsburgh Graduate School of Public Health presented at the XVIII International AIDS Conference suggests it would have a very small effect on reducing HIV incidence in the United States. Circumcision is thought to reduce the risk of HIV transmission by removing cells in the foreskin that are most susceptible to infection by the virus. Clinical trials conducted in...

PSI responds to comments by Bill Gates and former President Bill Clinton on the life-saving intervention VIENNA, Austria, July 19 /PRNewswire-USNewswire/ -- Following the remarks on male circumcision made today by former President Bill Clinton and philanthropist Bill Gates, PSI will release the results of a groundbreaking study on a new model of efficiency that will allow for quality and cost-effective scale-up of male circumcision. "Our first task is to scale up the prevention efforts...

What do a trout, sea anemone, rooster, fly and man have in common? Just as styles in sexy clothes or fashion change from year to year and culture to culture, "sexy" genes, or genes specific to sex, also change rapidly. But there is one sex-specific gene so vital, its function has remained unaltered throughout evolution and is found in almost all animals, according to new research from Northwestern University Feinberg School of Medicine. The gene, called Boule, is responsible for sperm...

OPEN LETTER TO TASK FORCE MEMBERS SAYS FAILING TO GIVE SAME PROTECTIONS TO BOYS AND GIRLS IS "EXTRAORDINARY BETRAYAL" OF MEDICAL ETHICS, HUMAN RIGHTS TARRYTOWN, N.Y., July 1 /PRNewswire-USNewswire/ -- In the wake of the American Academy of Pediatrics' (AAP) short-lived call to amend the national ban on female genital cutting, Intact America - the largest organization championing all children's human right to an intact body - published an open letter to an AAP Task Force on Circumcision...

"ËœSonic hedgehog' helps regenerate critical nerve that runs along prostate After men have surgery to remove a cancerous prostate gland, up to 80 percent of them will lose the ability to have an erection because of damage to a critical nerve that runs along the prostate. New research from Northwestern University Feinberg School of Medicine shows the damaged nerve can be regenerated more quickly with a protein called sonic hedgehog delivered via a nanofiber gel. The study, done with...

How safe is circumcision? A systematic review, published in the open access journal BMC Urology has found that neonatal and infant circumcision by trained staff rarely results in problems. Risks can be higher among older boys, especially when undertaken by untrained providers with inappropriate equipment. Dr Helen Weiss, from the London School of Hygiene & Tropical Medicine, UK, studied the medical literature relating to circumcision. Dr Weiss said, "We identified 52 studies from 21...

Changes in bacteria within the penis microbiome documented for the first time Circumcision, which substantially lowers HIV risk in men, also dramatically changes the bacterial communities of the penis, according to a study led by scientists at the Translational Genomics Research Institute (TGen) and Johns Hopkins University and published Jan. 6 in the scientific journal PLoS ONE. And these bacterial changes may also be associated with earlier observations that women whose male partners are...

Prostate
2013-03-04 15:21:55

The male prostate gland acts as an exocrine gland in the male reproductive system. It is a firm, partly muscular, chestnut sized gland near the neck of the urethra in males. Formation and Orientation The prostate is usually formed within the ninth week of the embryonic stage in reproductive development. The prostate can be separated into either “lobes” or “zones”. When looking at a prostate divided into zones, there are four distinct regions. The first zone is the Peripheral...

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...
