Yale researchers have discovered how the "guardian of the genome'' oversees quality control in the production of sperm – and perhaps in many other cells as well. The research published online Feb. 16 in the journal Current Biology opens up the potential of developing new forms of birth control and fertility treatment – and even new ways to combat many forms of cancer. Sperm and other cells go through a sort of inspection process triggered by a key regulatory gene, p53, which...

(Ivanhoe Newswire)--The perfect male birth control contraceptive would be cheap, reliable, and reversible. It would have few side effects and would be long lasting. A new study used therapeutic ultrasound equipment in the sperm count reduction of male rats to levels which would result in infertility in humans. Ultrasound's capabilities as a male contraceptive were first acknowledged almost 40 years ago. Although the equipment used back then is now outdated and no longer around, researchers...

Is there a simple, inexpensive, reversible male contraceptive coming to a clinic near you soon? A quick visit to a doctor´s office may soon be all that is needed for males to do their part for contraception. The journal Reproductive Biology and Endocrinology details a study using commercially available therapeutic ultrasound equipment to reduce sperm counts of male rats to levels which would result in infertility in humans. A team led by the University of North Carolina´s Dr....

A new study shows the production of sperm is more biologically taxing than previously thought, and expending energy on it has significant health implications. In research published in PLoS ONE, Dr Damian Dowling of Monash University's School of Biological Sciences and Professor Leigh Simmons of the University of Western Australia have investigated the trade-off between sperm quality and immunity. The researchers used the Australian cricket, Teleogryllus oceanicus to prove that the...

The ideal male contraceptive would be inexpensive, reliable, and reversible. It would need to be long acting but have few side effects. New research published in BioMed Central's open access journal Reproductive Biology and Endocrinology used commercially available therapeutic ultrasound equipment to reduce sperm counts of male rats to levels which would result in infertility in humans. Ultrasound's potential as a male contraceptive was first reported nearly 40 years ago. However the...

Who knew that male fertility depends on sperm-cell architecture? A University of Illinois study reports that a certain omega-3 fatty acid is necessary to construct the arch that turns around, immature sperm cell into a pointy-headed super swimmer with an extra long tail. "Normal sperm cells contain an arc-like structure called the acrosome that is critical in fertilization because it houses, organizes, and concentrates a variety of enzymes that sperm use to penetrate an egg," said Manabu...

Melissa Perry, Sc.D., M.H.S., professor and chair of the Department of Environmental and Occupational Health at the GW School of Public Health and Health Services and adjunct associate professor at the Harvard School of Public Health, led an observational study indicating that environmental exposure to organochlorine chemicals, including Polychlorinated Biphenyls (PCBs) and p,p´-DDE (the main metabolite of the insecticide DDT) can affect male reproduction. The research was published...

Mouse Sperm Grown In A Petri Dish, Again

Just months after Japanese fertility scientists created artificial sperm from stem cells to make baby mice, German and Israeli researchers are making a major breakthrough of their own that could soon see human sperm grown in the laboratory. The development could soon give infertile men the ability to father their own children rather than relying on donor sperm from another man. The research team, led by Professor Stefan Schlatt, at Muenster University in Germany, were able to grow sperm...

Breakthrough offers new hope in fight against global pandemic Scientists at the Gladstone Institutes have discovered new protein fragments in semen that enhance the ability of HIV, the virus that causes AIDS, to infect new cells–a discovery that one day could help curb the global spread of this deadly pathogen. HIV/AIDS has killed more than 25 million people around the world since first being identified some 30 years ago. In the United States alone, more than one million people...

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...
