Findings may lead to development of novel approach for male contraceptionVirginia Commonwealth University School of Medicine researchers have discovered a gene involved with the production of sperm that may contribute to male infertility and lead to new approaches to male contraception.One in six couples trying to conceive a baby is affected by infertility, according to the American Fertility Association "“ and in about half of these cases, a male factor is present. Sperm defects are often...

GPx5, an antioxidant protein that protects immature spermatozoa once they have left the testicle, has been identified by the GReD Unit (1) (CNRS / INSERM / Universities de Clermont-Ferrand).  This discovery by Joël Drevet and his team establishes a link between post-testicular oxidative stress and degradation of the DNA in male gametes.  These findings, which presage a major clinical impact "“ particularly in the context of medically-assisted procreation (MAP) "“ have been...

The promise of stem cell therapy may lie in uncovering how adult cells revert back into a primordial, stem cell state, whose fate is yet to be determined. Now, cell scientists at the Johns Hopkins University School of Medicine have identified key molecular players responsible for this reversion in fruit fly sperm cells. Reporting online this week in Cell Stem Cell, researchers show that two proteins are responsible redirecting cells on the way to becoming sperm back to stem cells."We...

A U.S. expert on urological conditions advises parents to take action if their son complains of testicular pain. Sandra Vassos of the American Urological Association Foundation says if the testicular pain is sudden and severe and there is swelling on one side, the boy may have testicular torsion and should be taken to an emergency room. Testicular torsion is very rare, but can be serious if not treated promptly, Vassos says. The condition occurs when the spermatic cord -- a cord by which a...

Attractive males release fewer sperm per mating to maximize their chances of producing offspring across a range of females, according to a new paper on the evolution of ejaculation strategies. The findings by researchers at UCL (University College London) and the University of Oxford suggest that, paradoxically, matings with attractive males may be less fertile than those with unattractive ones.In a paper to be published in the journal American Naturalist, the team mathematically modeled a...

REMOVAL OF HEALTHY FUNCTIONING TISSUE VIOLATES MEDICAL ETHICS, HUMAN RIGHTS OF BABY BOYS WHO CANNOT GIVE INFORMED CONSENT NEW YORK, June 25 /PRNewswire-USNewswire/ -- Parents, pediatricians and health and human rights activists today announced the launch of INTACT AMERICA and its website -- www.intactamerica.org -- to change how America thinks about male circumcision. The national campaign argues that painful and medically unnecessary surgery to remove healthy genital tissue from...

Joel Drevet and colleagues, at Clermont Université, France, have identified a protein that helps protect immature mouse sperm after they have been released into a region of the testis known as the epididymis, which is where they undergo maturation. Although male mice lacking this protein, Gpx5, had normal looking sperm and were equally as efficient as normal male mice at fertilizing female mice, an increased incidence of miscarriages and fetal developmental defects were observed when...

SALT LAKE CITY, June 11 /PRNewswire/ -- Clinical Innovations has launched its new disposable circumcision device, the AccuCirc, to help clinicians provide precise, consistent and reliable circumcision outcomes. Touted as the only significant innovation in circumcision of the past 50 years, the AccuCirc utilizes revolutionary technology to protect the glans, ensure adequate hemostasis, and deliver the precise cut of the foreskin in a single actuation. The AccuCirc uses two innovative...

New research from Spain shows that men who eat healthier diets might also have healthier sperm."A healthy, well-balanced diet is not just important for preventing diseases like diabetes, high cholesterol, or hypertension, but it may be useful for preserving or improving your reproductive health too," Dr. Jaime Mendiola of the University of Murcia, the lead researcher on the study, told Reuters Health via e-mail.Mendiola and his team noted in the journal Fertility and Sterility...
