Breakthrough in understanding the causes of unexplained male infertility

The diagnosis of male fertility is usually performed through the observation of the sperm in the microscope. However, a normal quality semen does not guarantee an adequate fertility. In fact, there is a considerable proportion of cases of unexplained infertility and data suggest that abnormal sperm function may have a genetic or molecular origin.

New survey shows women trying to get pregnant worry about fertility

For many women, the decision to get pregnant can take on a life of its own. In fact, according to a survey conducted for SpermCheck- Fertility, 42% of those who conceived say they became obsessed with getting pregnant once they started trying. Yet just 10% say their partner shared this obsession.

Oxidative stress in sperm linked to male infertility

Universitat Autònoma de Barcelona (UAB) patented an innovative system to specify in a simple, cost-effective and reliable manner the infertility of a person through the study of oxidative stress on sperm, a parameter rarely studied until now.

Artificial testes being developed to help infertile men produce sperm

Californian researchers are trying to create an artificial testicle that will produce human sperm. Dr. Paul Turek, director of the Turek Clinic in San Francisco, which specializes in male infertility, said the goal is not to create a testicular implant for men, but a “sperm-making biological machine” that will help scientists learn more about just what causes male infertility. “We’re trying to recreate the process of sperm production in a three-dimensional system,” Turek said. “Simple laboratory conditions can’t get it done in humans. Our concept is to actually recreate the testicle itself.”

A Daddy’s heart is healthier: Study

A new study shows that fathers are less likely to die of heart disease than men who’ve never had kids. This raises questions about a possible biological link between male infertility and overall health. Other recent studies have found a connection between testicular and prostate cancer and infertility.

Male infertility cause found in defective gene

Researchers have found a new cause of infertility that could allow millions of infertile couples around the world to have a child. The team found a common gene mutation that causes sperm to be far less able to swim through the mucus of the cervix and reach the egg.

Varicocele surgery may increase testosterone production

Low testosterone linked to varicoceles

As many as 15 percent of men have varicoceles, masses of enlarged and dilated veins in the testicles. There is new evidence that varicoceles, long known to be a cause of male infertility, interfere with the production of testosterone -- a crucial hormone to maintaining men's health. There is good news too: Microsurgery can increase testosterone levels in these men. Results of new research by physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center are in a recent edition of BJU International.

Non-steroidal, oral contraceptive for men

Researchers at Columbia University Medical Center are honing in on the development of what may be the first non-steroidal, oral contraceptive for men. Tests of low doses of a compound that interferes with retinoic acid receptors (RARs), whose ligands are metabolites of dietary vitamin A, showed that it caused sterility in male mice.

Queen's University develops groundbreaking new test for male infertility

A groundbreaking new test for male infertility, which will save time, money and heartache for couples around the world, has been developed at Queen's University Belfast.

SpermComet: New test for male infertility

A new test for male infertility will save time, money and heartache for couples around the world, scientists have claimed. Queen's University Belfast said that more than a decade's research by Professor Sheena Lewis, who leads its Reproductive Medicine research group, had delivered a medical breakthrough.

Insight into male infertility

Around one in 20 men is infertile, but despite the best efforts of scientists, in many cases the underlying causes of infertility have remained a mystery.

Mouse sperm created in lab: Hope for male infertility

In a scientific breakthrough, researchers report that they've grown mouse sperm from testicular tissue in the laboratory, a development that could advance the field of infertility in human males. Although still proven in mice, “this is a small but important step in understanding how sperm are formed, which may, in time, lead to us being able to grow human sperm in the laboratory,” said Dr. Allan Pacey, senior lecturer in andrology at the University of Sheffield in England, who is familiar with the study results.

FRSQ, NSFC announce funds for genomic research on male infertility

The Fonds de la recherche en santé du Québec, Génome Québec and the National Natural Science Foundation of China are pleased to announce the funding of a first project as part of their joint program for research on genomics and diseases, which was launched in July 2010.

Uterine health is more relevant for fetus to achieve normal birth weight, full gestation

For women seeking pregnancy by assisted reproductive technologies, such as in-vitro fertilization, a new study shows that the health of the uterus is more relevant than egg quality for a newborn to achieve normal birth weight and full gestation.

Lifetime tool for families created through sperm donation

Starting a family the "old-fashioned way" is becoming less common. Only 25% of American households are made up of a husband, wife, and a child. The fertility field is continually growing with advances in scientific technology, and infertile patients have more options for conceiving -- including the use of donor sperm. Along with the medical advances comes the continual need for emotional support for both the parent and children.

Researchers identify gene mutation for that is essential for correct protein-processing in cells

A Jackson Laboratory research team led by Professor Patsy Nishina, Ph.D., has identified a mutation in a gene that's essential for correct protein-processing in cells. Defects in protein folding are associated with a variety of abnormalities and diseases.

First step in development of artificial human testicle

After more than 30 years of unsuccessful efforts by numerous investigators, researchers have now found a way to propagate primary human Sertoli cells in the laboratory. Derived from the testis, it has been difficult to maintain Sertoli cells, the "nurse" cells responsible for overseeing sperm production, outside of the human body.
