(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 Although the equipment used back then is now outdated and no longer around, researchers...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.

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...

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...

Listen Up Men! Your Laptop’s Wi-Fi Could Be Killing Your Sperm
2011-11-29 08:24:18

Wi-Fi technology could be dangerous to a man´s sperm quality, suggests a new study published in the journal Fertility and Sterility. Argentinean scientists, led by Conrado Avendano of the Nascentis Center for Reproductive Medicine in Cordoba, describe in their report how they got semen samples from 29 healthy men, placed a few drops from those samples under a laptop with a Wi-Fi connection, and then used the laptop to do various everyday tasks. Within four hours of use, 25 percent...

SAN RAMON, Calif., Nov. 21, 2011 /PRNewswire-USNewswire/ -- From Jennifer Lahl and The Center for Bioethics and Culture, producers of the award-winning Eggsploitation (2010), Anonymous Father's Day presents the untold stories of children of sperm donors. Featuring the heart-rending reflections of now adult children fathered anonymously, these donor-conceived children share the pain, longing and uncertainties created by the secrecy of their conceptions. Each has a real, biological father...

A Ben-Gurion University of the Negev researcher has achieved a significant breakthrough in male fertility, producing normal sperm from mouse cells. "This study may open new therapeutic strategies for infertile men who cannot generate sperm and/or pre-pubertal cancer patients at risk of infertility due to aggressive chemo- or radiotherapy and cannot cryopreserve sperm as in adult patients," explains Prof. Mahmoud Huleihel, of BGU's Shraga Segal Department of Microbiology and Immunology in...

San Francisco State University study published by the journal Genetics Compared to most other cells in an organism, sperm undergo a radical transformation to become compact and mobile delivery systems for paternal DNA. Even though sperm looks and moves quite differently across species, SF State researcher Diana Chu and colleagues now say that there are at least a few key enzymes that are critical for sperm development and mobility in species as different as mice and nematode worms. The...

Cells Are Crawling All Over Our Bodies
2011-10-19 03:28:51

Biologists at Florida State devise new way to watch how cells move For better and for worse, human health depends on a cell's motility —— the ability to crawl from place to place. In every human body, millions of cells —are crawling around doing mostly good deeds ——— though if any of those crawlers are cancerous, watch out. "This is not some horrible sci-fi movie come true but, instead, normal cells carrying out their daily duties," said Florida State...
