Causes of male infertility

Two reports from physician-scientists at NewYork-Presbyterian Hospital/Weill Cornell Medical Center shed new light on male infertility.

Defects in Jhdm2a gene could be the cause for some cases of male infertility

Scientists at the University of North Carolina at Chapel Hill have identified a gene crucial to the final step of the formation of a functional sperm cell.

Study looks at mitochondrial variation in sperm traits and sperm competitive ability

University of Nevada, Reno researchers Jeanne and David Zeh of the Department of Biology have received a five-year, $650,000 grant from the National Science Foundation to investigate the effects of natural mitochondrial variation on sperm traits and sperm competitive ability.

New cell death pathway involved in sperm development

Heavy and bulky sperm would not be good swimmers. To trim down, sperm rely on cell death proteins called caspases, which facilitate the removal of unwanted cellular material and radically remodel these cells into their sleek, light shape.

Men physcologically affected by fertility problems as much as women

Although most psychosocial research into infertility is centred round the unhappiness it causes women, men suffer just as much, a scientist will tell the 23rd annual conference of the European Society of Human Reproduction and Embryology today (Wednesday 4 July).

Discovery of gene and mechanism essential to the embryonic development of the epididymis

Human sperm cells travel up to 6 meters in their transit from testes to penis, and most of that journey occurs in the epididymis, a tightly coiled tube that primes the cells for their ultimate task: fertilization.

Cornell University establishes Center for Reproductive Genomics

Cornell University has established the Center for Reproductive Genomics, which will combine basic research in reproductive sciences on Cornell's Ithaca campus with one of the country's leading fertility clinics at Weill Cornell Medical College (WCMC) in New York City.

Novel two-step mechanism ensures that all cilia beat in unison

Cilia, tiny hair-like structures that propel mucus out of airways, have to agree on the direction of the fluid flow to get things moving. Researchers at the Salk Institute for Biological Studies discovered a novel two-step mechanism that ensures that all cilia beat in unison.

Genetic mutation that prevents sperm production found

Up to 15 percent of couples of childbearing age struggle with the heartache of infertility.

Would be dads advised to stay out of the hot tub

The team led by Dr. Paul J. Turek, a urologist and professor at the University of California, San Francisco, say hot baths can lead to male infertility.

Newborns with respiratory distress should be evaluated for primary ciliary dyskinesia

Reviewing published reports, Ferkol and Margaret Leigh, M.D., professor of pediatrics at the University of North Carolina at Chapel Hill (UNC), found that neonatal respiratory distress was a common clinical symptom of PCD, a chronic airway disease that affects about 1 in 15,000 children.

World-first stem cell research may help male infertility

Scientists have shown for the first time that sperm grown from embryonic stem cells can be used to produce offspring.

Mice sperm grown in a lab produces baby mice

In ground breaking research scientists have for the first time produced mice using sperm grown in the laboratory from embryonic stem cells.

Study links high levels of nitric oxide to infertility and sperm DNA damage

Iranian scientists have linked a chemical that plays an essential role in many bodily functions to sperm DNA damage and male infertility, the 22nd annual conference of the European Society of Human Reproduction heard.

19 Jun 2006

New tool helps predict pregnancy outcomes

Physicians must consider a number of variables when treating couples who cannot naturally conceive because of factors involving both the woman and man.

23 Feb 2006

New understanding of the molecular genetics of successful fertilization

A new paper in the February 15th issue of Genes & Development lends novel insight into the cellular changes that occur in sperm while they reside in the female reproductive tract - providing a new understanding of the molecular genetics of successful fertilization.

14 Feb 2006

Chinese medicine shows promise as treatment for sperm genetic abnormalities

Bioscientists from the University of Kent have called for clinical trials to further investigate how traditional Chinese medicine (TCM) may have a positive effect on sperm genetic abnormalities, and thereby influence the success rate of male infertility treatment.

Protein amplifies DNA injury signals - cues genetic repair mechanism to prevent tumors

A Mayo Clinic-led research collaboration has discovered that the protein MDC1 amplifies weak DNA injury signals so genetic repair can begin.

Acupuncture may help some men overcome infertility

Researchers found five weeks of acupuncture treatment reduced the number of structural abnormalities in sperm and increased the overall number of normal sperm in a group of men with infertility problems.
