According to the conclusions of a new scientific study, it would appear that cell phone use has been directly linked to a decrease in fertility in men. Excessive exposure to this technology leads to low sperm quality, and also the inability to conceive children. As such, the research team behind this research suggest... |

Men are known for being attracted to either the face or body of women, but a new study suggests that the target of their eyes is in fact dictated by the expectations they have of the resulting relationship.In other words, if men are looking for a one-night stand or a fling, they are very likely to look at the woman&#... |

A group of British investigators from the University of Sheffield has recently determined that the patterns in which people marry are a very clear indicator of how the overall fertility patterns fluctuate. In other words, they believe, the way people marry can easily influence the fertility rates parents exhibit. The... |

Once fertility treatments are completed, many embryos remain frozen, a byproduct of women's treatment options, which include the possibility of preserving eggs if regular therapies fail. The logic behind this is for patients to be able to have children, even if through in-vitro fertilization. But most women have... |

Multiple studies have shown that animals that consume large amounts of soy beans are likely to have a lower fertility rate. On the other hand, research regarding the impact of soy on humans revealed that the chemicals found in this plant have absolutely no effect on fertility. Now, a new study carried out at the Harv... |

Even in these modern days, when the lifespan of humans surpasses an all time record, women over 40 are generally believed too old to have babies, yet somehow there is no mention of the limit age men become less fertile at. If 40 looked like a rather young age to stop having children, a new study now shows that men ol... |

Premature babies are considered those born before 37 weeks. Even if there are a lot of studies showing the short term effect on the health of the babies of the premature births, a new research investigating about 1.2 million births in Norway pointed the effect of a premature birth in the health of the adults. The stu... |

Being overweight is more than a risk for your health: it can completely end up your lineage. Being too skinny translates too low sex drive and sterility, in both women and men, but the opposite too seems to strike on fertility level: a new Dutch research published in the Human Reproduction journal shows that an overw... |

I'm sure you're quite well informed on many aspects related to HIV, syphilis or gonorrhea, but the STD you're more likely to experience is Chlamydia, the "Silent Epidemic" (called so because in women it may not induce any symptoms and will linger for months or years before being diagnosed). In men, Chl... |

Sex works on the principle of positive feed back: more sex just improves our 'performance'. A team from Sydney University says that men with damaged sperm should have sex daily to increase the chances of getting their partner pregnant. In many cases, couples with fertility issues abstain from sex for severa... |

We are a unique gene complex, so, if we function so differently from one individual to another, why not use a personalized IVF (in vitro fertilization)? Especially as 90 % of the women receive the wrong dose when undergoing IVF. An international team has developed an easy-to-use mathematical formula that permits a pe... |

It is well known that stress can indeed suppress reproduction in humans. Researches showed that stress-reducing therapy made women regain their fertility. Scientists at Emory University in Atlanta, Georgia, found cognitive behavior therapy alone was enough to restore periods in some women. High levels of stress hormo... |

It is easy to blame it on the woman, but in 40 % of the couples, the man is the sterile part. Now, a team at the Feinstein Institute for Medical Research found an immune factor that regulates human semen, inducing fertility or sterility in a man. The macrophage migration inhibitory factor (MIF) appears to be crucial ... |

You may have heard that the tiger is menaced by the demand on the Chinese black market of tiger penis bone. Tiger penis bone for the same people encompasses the tiger's power, including the sexual one. Of course, it's like chewing chicken or pork bones, but the poachers are menacing the wild tigers because ... |

Male vanity hardly copes with the fact that in 50 % of the cases, the couple's infertility is the man's fault. It is even trickier to get him to see a doctor for a fertility evaluation. The new at-home screening test, called Fertell, has solved this. This is the first at-home device to test the concentratio... |

The common concept on female fertility states that at birth females have all their eggs inside their undeveloped (yet) ovaries and these eggs are released one by one (sometimes more than one) at each ovulation. At menopause, the ovaries are deserted by any egg. But in 2004 a Harvard team led by reproductive endocrino... |

It seems that in the case of women, fertility is not just an innate quality but also one adjusted by life conditions in early life. This conclusion was reached by a team at University College London which analyzed hormone levels in women who migrated to the UK from Bangladesh at various life stages. The researchers f... |

We know that parasites are the bad guys that trigger diseases. Some are lethal, like malaria, others just decrease fitness (like gut worms). Those attacking the sexual apparatus affect fertility. Wolbachia is a bacterium encountered in over 20 % of all insects and known to decrease female fertility. But a new resear... |

It seems there is a huge gap between Japan's sex toys, porn, hentai and sexy TV shows and the way real sex occurs there. Japan's population is estimated at around 127,463,611 and is correlated with one of the highest life expectancy rates in the world, of 81.25 years (in fact, today's oldest living per... |

Women resorting to IVF (in vitro fertilization) take drugs to boost egg maturation in their ovaries. These ovules are extracted by doctors and fertilized in the laboratory; but some women's ovaries cannot generate any egg even under medication, and in such cases the treatment fails. As IVF treatment means $10,00... |

Statistics show that couple infertility is due equally to men as to women. Male sterility is triggered by impairment in the multiplication and development of the germ cells (that generate sperm cells) or of their supporting tissues.

About 7 % of American couples are sterile. 30 % of the cases are attributed to the man, 30 % to the woman and the rest to both partners or to unknown reasons. Drugs or surgery can treat 85-90 % of infertility cases; less than 3 % require in vitro fertilization (IVF), a costly procedure. "Couples really prefer having ... |
