University of Veterinary Medicine, Vienna An increasing number of men suffer from fertility problems, especially in western society. The general belief is that many problems may be related to stress but it is possible that some of them may arise because men simply have intercourse too infrequently. This is the intriguing implication of recent research at the University of Veterinary Medicine, Vienna, that has just been published in the international online journal PLoS ONE. Fertility...

Variation In Sperm Length Is Not A Good Sign
2012-11-13 16:38:55

Brown University A new study published online in the journal Human Reproduction finds that the greater the inconsistency in the length of sperm, particularly in the tail (flagellum), the lower the concentration of sperm that can swim well. The finding offers fertility clinicians a potential new marker for fertility trouble that might trace back to how a patient´s sperm are being made. Perhaps variety is the very spice of life, but as a matter of producing human life, it could be...

New Technique Allows Scientists To Track Sperm Movements
2012-09-18 14:50:46

Lee Rannals for redOrbit.com — Your Universe Online A new imaging technique is allowing scientists to get more up close and personal than ever before with human sperm. UCLA researchers developed an imaging technique allowing them to track the movements of 1,500 human sperm at one time in 3D. Imaging moving objects like sperm has been difficult to do through microscopes and other tools, so scientists developed the new technique to watch sperm like never before. The new...

New Hope For Male Birth Control Pill

Watch the Video: Potential New Male Contraceptive Connie K. Ho for redOrbit.com — Your Universe Online There are many contraception options for women, but until now, there has not been much done in the area of contraceptives for males. Now researchers believe that a small molecule that can move past the barrier between blood and sperm into a space where sperm is processed may become the future of male conception. The compound would be the first successful and hormone-free birth...

Male Fertility Gets Boost From Eating Walnuts

Connie K. Ho for redOrbit.com — Your Universe Online Researchers from the University of California, Los Angeles (UCLA) recently discovered that consuming 2.5 ounces of walnuts a day can heighten semen quality in young men. The paper, published in a recent edition of Biology of Reproduction´s Papers-in-Press, included data that showed that 75 grams of walnuts per day could increase sperm motility, vitality, and morphology of men between the ages of 21 and 35. The team of...

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...

(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,...

How Flowers Pollinate With Precision
2012-05-17 11:25:35

Next Mother's Day, say it with an evolved model of logistical efficiency – a flower. A new discovery about how nature's icons of romance manage the distribution of sperm among female gametes with industrial precision helps explain why the delicate beauties have reproduced prolifically enough to dominate the earth. In pollination, hundreds of sperm-carrying pollen grains stick to the stigma suspended in the middle of a flower and quickly grow a tube down a long shaft called a style...

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...
