Latest findings in male reproduction research

The XVIII North American Testis Workshop, chaired by Population Council senior scientist Matthew Hardy, will be held 30 March - 2 April in Seattle, Washington. Participants will discuss findings from the large body of recent research on male reproduction.

Public concerns show need for independent fertility regulation as great as ever

The public concerns and future developments which underpin the need for ongoing independent regulation of fertility treatment and research were spelt out in a keynote speech by Angela McNab, Chief Executive of the Human Fertilisation and Embryology Authority, at the HFEA’s annual conference this week (15 March).

Innovative computer modeling technique predicts how protein molecule behavior in response to environmental conditions

In a development that could have great significance for efforts to understand how the basic molecular machinery of life works, researchers at the University of Texas Medical Branch at Galveston (UTMB) have successfully applied an innovative computer modeling technique to predicting how protein molecules will behave in response to different environmental conditions.

Most infertile women want to choose the sex of their child

Many women being treated for infertility would choose the sex of their next child if given the option and those who were childless would choose baby girls and boys in approximately equal numbers.

Significant number of women being treated for infertility would choose the sex of their next child

A new survey says a significant number of women being treated for infertility would choose the sex of their next child if given the option -- and those as yet childless would choose baby girls and boys in approximately equal numbers.

Protein circulating in the blood delivers selenium to germ cells, enabling normal development of sperm

A paper to be published in the journal Biology of Reproduction offers evidence that a protein circulating in the blood of mammals delivers the dietary micronutrient selenium to germ cells, enabling these cells to develop into normal sperm.

Way to detect early signs of testicular cancer

Danish researchers have discovered a way to detect early signs of testicular cancer before it has started to spread. Their findings are the first step towards developing a simple screening test for men at risk of the disease.

Genetic manipulation cuts nerve damage, boosts life span

A novel genetic manipulation significantly extends the life spans of flies by reducing the amount of wear and tear suffered by nerve cells in adults, according to new work published in Cell Metabolism. The findings support the idea that therapies designed to protect the adult nervous system by curbing the production of damaging free radicals might effectively increase longevity in other animals, including humans, the researchers said.

US rates of early death and disability from sexual behaviour triple those of other wealthy nations

The rates of premature death and disability attributable to sexual behaviour in the United States are triple those of other wealthy nations, suggests research in Sexually Transmitted Infections.

Increasing trend in society to be more open about the use of sperm donors

Two studies to be published tomorrow (Thursday 27 January) in Europe's leading reproductive medicine journal, Human Reproduction provide a generally optimistic picture about attitudes towards the increasing trend in society to be more open about the use of sperm donors.

Researchers have uncovered evidence of sexual reproduction in a single-celled organism long thought to reproduce asexually

The finding by John M. Logsdon, Jr., assistant professor in the UI College of Liberal Arts and Sciences Department of Biological Sciences and the Roy J. Carver Center for Comparative Genomics, and colleagues from the UI and Roanoke College (Virginia), provides the first clear evidence that meiosis arose very early in eukaryotic evolution, bringing science one step closer to understanding the mystery of sexual evolution.

Now significantly easier to search long stretches of DNA for genetic changes associated with disease

The researchers developed a method called direct genomic selection that accelerates the transition between family or population-based studies of disease inheritance patterns and identification of genetic variations that may contribute to disease.

Notebook computers can have a negative effect on male fertility

US fertility experts are warning teenage boys and young men to consider limiting the time that they use notebook computers positioned on their laps, as long-term use may affect their fertility.

Human endogenous retroviruses (HERVs)

Human endogenous retroviruses (HERVs) have been the subject of a great deal of investigation in recent years. It has been established that HERVs cause some genetic diseases and there is strong circumstantial evidence for a link to some types of cancer and autoimmune diseases, but what else do we need to know about these unique organisms?

Study gives U.S.a 'C' grade for reproductive health

In a comprehensive study released today by Population Action International (PAI) - an independent policy and research organization based in Washington, D.C. - the United States ranks 16th and receives a "C" on a list of 21 donor countries graded according to their financial and political support for international reproductive health and population programs.

Women with recurrent miscarriage and infertility are undergoing tests and treatments that have no scientific rationale

Women with recurrent miscarriage and infertility are undergoing tests and treatments that have no scientific rationale and are linked with known risks to mother and fetus, warn researchers in this week's BMJ.

Patented fibrin-based matrices and tissue may open doors for tissue and organ engineering

Virginia Commonwealth University engineers and scientists have developed and patented a unique technique to grow three-dimensional tissues and organs in a mold made from material the human body naturally uses to repair wounds, potentially eliminating the chance for rejection.

Safe, effective and reversible alternative contraceptives for men

Most men know when their family is complete, and vasectomy remains the most effective and safest form of sterilization. Around 10% of vasectomized men in the U.S desire vasectomy reversal due to the high divorce rate in this country and other life circumstances.

Five advanced tests provide answers to couples with unexplained infertility

For couples struggling with infertility, "all routine tests came back negative" are not the words they want to hear. With up to 15% of couples with "unexplained infertility" and another 3% struggling with recurrent pregnancy loss, advanced tests help doctors find answers for their most challenging cases.

Shp2 protein plays a critical role in obesity

A team of researchers led by The Burnham Institute's Gen-Sheng Feng, Ph.D. has discovered that a protein called Shp2 plays a critical role in obesity.
