According to RF Safe, cell phone radiation has now been linked to erectile dysfunction (ED), lower sperm count, and male infertility in the Environmental Health Trust's latest newsletter. RF Safe provides men several proven ways for reduced excessive cell phone radiation exposure. Las Angeles, California (PRWEB) April 02, 2014 As news of the Environmental Health Trust's latest March 28th, 2014 newsletter links cell phone radiation to male reproductive problems. The report reviews...

New Findings Could Lead To Novel Diagnostic Tests And Treatments For Male Infertility
2014-02-19 10:38:25

American Institute of Physics To better understand the causes of male infertility, a team of Bay Area researchers is exploring the factors, both physiological and biochemical, that differentiate fertile sperm from infertile sperm. At the 58th Annual Biophysical Society Meeting, which takes place Feb. 15-19, 2014, in San Francisco, Calif., the team will present its work to identify and characterize proteins known as ion channels, which are crucial for sperm fertility and expressed within a...

Sperm meet egg NEW YORK, February 14, 2014 /PRNewswire/ -- Pressure to make Valentine's Day all about sex and passion can feel daunting for 1 in 10 women in the US who face difficulty conceiving. Moreover, over the last three decades, women have been waiting longer to start having children. However, when it comes to fertility, age matters; both women and men are at their most fertile in their early twenties. "Over recent years, establishing a career, getting on the...

Impaired fetal growth and exposure to maternal smoking correlated with lower measures of sperm quality Studies over the past 20 years have suggested (though not unequivocally confirmed) that semen quality is in decline, reflected most evidently in falling sperm counts and reduced sperm motility. The explanations have been controversially attributed to environmental factors (such as exposure to toxins) and to male smoking. Now, a new study based on a 20-year follow-up of one of the world's...

BOGOTA, Colombia, Sept. 3, 2012 /PRNewswire/ -- Water buffalo breeding, an industry that actually uses artificial insemination, started using a new variant of the procedure in which the sex of the offspring can be chosen and it is called "Sexed Semen." This experience had never been used for the water buffalo species until this year, when Colbufalos, a company dedicated to buffalo breeding, located in Cordoba-Colombia, and led by Juan Gonzalo Angel, obtained the first successful results....

First Genetic Sequence Of Individual Human Sperm
2012-07-20 07:58:23

Connie K. Ho for redOrbit.com — Your Universe Online Sperm cells can look the same with a similar tadpole appearance. However, the cells showcase differences among the genes. Recently, researchers were able to capture an image of the varieties among genes which they say is particularly helpful in understanding the genome and male fertility. The research is featured in the July 20 edition of Cell, a Cell Press journal. The scientists believe that the methods used could help...

New Gene Discovery Could Lead To Non-Hormonal Contraceptive For Men
2012-05-25 09:27:07

Male contraception may be a possibility thanks in part to a discovery of a new key reproductive gene critical for production of healthy sperm, suggests Scottish scientists credited with the discovery. Researchers from Edinburgh University are hopeful their study, which involved mice, could lead to a new type of male birth control that doesn´t disrupt the production of hormones, something which often causes side effects such as mood swings. The researchers found that a gene known as...

(Ivanhoe Newswire) - A new type of male contraceptive could be created thanks to the discovery of a key gene essential for sperm development. This could lead to alternatives to the conventional male contraceptives which rely on the production of hormones, such as testerone. Research led by the University of Edinburgh, shows how the gene Katnal1 is critical to enable sperm maturity in the testes. If scientists can regulate Katnal1 in the testes, they could prevent sperm completely maturing,...

Sperm Crawl And Collide On Way To Egg
2012-05-07 14:12:38

Scientists at the Universities of Birmingham and Warwick have shed new light on how sperm navigate the female reproductive tract, 'crawling' along the channel walls and swimming around corners; with frequent collisions. Research results published today (Tuesday May 8, 2012) in the Proceedings of the National Academy of Sciences of the United States (PNAS) provide fresh insight into how sperm might find their way to the egg that will help to inform future innovation in the struggle to treat...

Experts from Durham University have identified a new gene that could help the development of fertility treatments in humans in the future. Scientists from Durham University, UK, and Osaka University, Japan, looking at fertility in mice, have discovered for the first time that the gene, which makes a protein called PDILT, enables sperm to bind to an egg, a process essential to fertilization. The team found that when the gene was 'switched off' in male mice, less than three per cent of...
