In contrast to women, men are fertile throughout life, but research at the Sahlgrenska Academy, University of Gothenburg, Sweden, has now shown that a fertilising sperm can get help from the egg to rejuvenate. The result is an important step towards future stem cell therapy.The risk of chromosomal abnormalities in the foetus is highly correlated to the age of the mother, but is nearly independent of the age of the father. One possible explanation is that egg cells have a unique ability to...

A Dutchman known as Europe's most committed sperm donor says he's fathered 46 children and is willing to keep at it. I do it because I know how hard it is for people who desperately want a child, said Ed Houben, a tourism guide from Maastricht. One of the reasons Houben is so popular, he said, is because many men stopped donating sperm three years ago when the United Kingdom said donors no longer could remain anonymous, The Sun reported Monday. As a result, British women are going to other...

Obese men should consider losing weight if they want to have children, according to new research presented at a meeting of the European Society of Human Reproduction and Embryology. Dr. A Ghiyath Shayeb, from the University of Aberdeen, Aberdeen, UK, said his research found that men with a higher body mass index (BMI) had lower volumes of seminal fluid and a higher proportion of abnormal sperm. "There is a very long list of health hazards from being overweight," said Dr Shayeb, the study's...

Obese men should consider losing weight before having children, because fatter men have less seminal fluid and more abnormal sperm, a Scottish researcher says. Dr. A Ghiyath Shayeb of the University of Aberdeen and colleagues looked at the results of seminal fluid analysis in 5,316 men who attended the Aberdeen Fertility Centre with their partners for difficulties in conceiving. The researchers said 2,037 of these men had complete data on their body mass index. The scientists divided the...

"Every sperm is sacred. Every sperm is great. If a sperm is wasted, God gets quite irate," goes the song from Monty Python's movie The Meaning of Life. If the lyrics strike you as funny, it's most likely because calling a sperm cell "sacred" sounds ridiculous when men can produce so many of them. In fact, the average male will produce roughly 525 billion sperm cells over a lifetime and shed at least one billion of them per month. A healthy adult male can release between 40...

British scientists warn male painters exposed to glycol ethers they may be more likely to have poor semen quality. Researchers at the Universities of Sheffield and Manchester in England found men exposed to glycol either -- found in many products including water-based paints -- have a two-point-five-fold increased chance of having a low motile, or moving, sperm count. Motile sperm move spontaneously and independently. Motility is an important factor in the fertility of men and the...
