Common pesticide may reduce fertility in women
Methoxychlor (MXC), a common insect pesticide used on food crops, may interfere with proper development and function of the reproductive tract, leading to reduced fertility in women, researchers at Yale School of Medicine write in the August issue of Endocrinology. view more (2005-09-13)
Study of Scottish Male Reproductive Health
A group of scientists and doctors from the Medical Research Council's Reproductive Biology Unit in Edinburgh are collaborating with colleagues in Public Health Sciences, The University of Edinburgh, in a study which forms part of a three year research programme on male reproductive health, jointly funded by the UK Department of Health, Department... view more...

No test needed for hand-foot genital syndrome in women without HOXA13 gene mutation
Hugh S. Taylor, M.D., professor in the Department of Obstetrics, Gynecology & Reproductive Sciences at Yale, and colleagues have found that women without mutations of the HOXA13 gene do not need to be subjected to x-rays and other tests for a rare condition called hand-foot genital syndrome. view more (2009-10-20)
Irresponsible use of fertility techniques will jeopardise the future of reproductive medicine warns new ESHRE president
Lausanne, Switzerland: The new president of the European Society of Human Reproduction and Embryology has warned that the future of reproductive medicine and the hopes of infertile couples could be put in jeopardy by the abusive use of fertility techniques. Professor Hans Evers from Academisch Ziekenhuis, Maastricht in the Netherlands, who takes... view more... (2001-07-04)
Fetal study highlights impact of stress on male fertility
Exposure to a combination of excess stress hormones and chemicals while in the womb could affect a man's fertility in later life, a study suggests. view more (2009-10-22)
Stress delays puberty
NWO research at Utrecht University has shown that when carp are subjected to stress, the development of their genital organs is delayed, so that they reach puberty later. It is likely that the stress hormone cortisol plays a major role in delaying puberty. Changes in water temperature produce stress in fish. Dimitri Consten of Utrecht University... view more...

Balancing male fertility and disease resistance
An international collaboration of researchers, headed by Dr. Shiping Wang (Huazhong Agricultural University, China) has discovered that a single gene in rice regulates both male fertility and pathogen resistance, providing an unexpected genetic link between reproductive success and the disease resistance. view more (2006-05-08)
Alcohol dependence among women is linked to delayed childbearing
Alcohol use during the teen years can not only lead to subsequent alcohol problems, it can also lead to risky sexual behavior and a greater risk of early childbearing. An examination of the relationship between a lifetime history of alcohol dependence (AD) and timing of first childbirth across reproductive development has found that AD in women is... view more...

Grandma, not mum, knows best
Research at the University of Sheffield, published today in Nature, has solved the mystery of why women live so long after their reproductive years have ceased. Basically, grandmothers can ensure the success of their own family by helping to increase the reproductive success of their adult children, thus propagating their own genes. Dr. Virpi... view more...

Social life-history response to individual immune challenge of workers of Bombus terrestris: a possible new cooperative phenomenon
Solitary organisms can minimise fitness loss from parasitism with a facultative change to an earlier reproduction. Such a shift of the reproductive effort gives the host a chance to compensate for the cost on future reproduction resulting from the infection. In the case of social insects, where brood care and reproductive effort are shared between... view more... (2004-02-05)
ESHRE continues ban on human reproductive cloning
"Irresponsible and unethical" says ESHRE The European Society of Human Reproduction and Embryology, which represents more than 4,000 international fertility experts, has renewed its moratorium on the cloning of human babies. The organisation first took a decision in 1999 to implement a five-year voluntary moratorium on reproductive cloning when it... view more... (2003-06-29)
Delayed breeding is not necessarily costly to lifetime reproductive success
Using 24 years of data from the longest-running study of a cooperative bird species on the African continent, researchers at the Universities of Bristol and Cape Town have cast doubt on one of the biggest assumptions in behavioral ecology: that a delayed start to breeding is necessarily costly to reproductive success. view more (2007-04-06)
Trends in prescription medication sharing among reproductive-aged women
Borrowing and sharing of prescription medications is a serious medical and public health concern. view more (2008-08-26)
Protein translation in sperm
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. view more (2006-02-15)
Males with elevated levels of testosterone lead shorter lives but have more success siring offspring
Comparative studies have studied testosterone levels and related them to mating systems and aggression, but very few studies have attempted to relate testosterone to fitness, that is, the combination of lifetime reproductive success and survival, in the wild or experimentally. view more (2006-04-13)
Procedure predicts embryos most likely to result in pregnancy
To address the high rate of multiple births resulting from in-vitro-fertilization (IVF), researchers at Yale School of Medicine and McGill University have developed a procedure that estimates the reproductive potential of individual embryos, possibly leading to a decrease in multiple-infant births and a higher success rate in women undergoing IVF. view more (2007-03-19)
Human Reproductive And Therapeutic Cloning
For Immediate Release Monday, 22 September 2003 International Scientific Body Calls For Ban On Human Reproductive Cloning More than 60 science academies from every continent in the world have called on the United Nations to adopt a ban on human reproductive cloning. The statement was issued by the InterAcademy Panel on International Issues (IAP),... view more... (2003-09-22)
New Research Finds Summer-Born Women Have Fewer Children
Women born in the summer have fewer children on average than women born at other times of the year, according to research published today (Thursday 29 April) in Europe's leading reproductive medicine journal Human Reproduction[1]. The findings, from a study of more than 3,000 Austrian women, show that despite the advent of modern contraception a... view more... (2004-04-26)
Human clones could be ticking time bombs, warns ethics expert
Lausanne, Switzerland: Cloning of adults or children for reproductive reasons should be ruled out completely until researchers have discovered ways of counter-acting the health risks associated with the procedure, an expert on the ethics of cloning said today (Wednesday 4 July). Dr Guido de Wert, a senior research fellow in Biomedical Ethics from... view more... (2001-07-04)
Stem-cell research and reproductive cloning laws should be separate (p 209)
The author of a Public Policy article in this week's issue of THE LANCET discusses recent failures of international organisations to establish clear policies with regard to stem-cell research and reproductive cloning. This will have implications for research scientists who will not be clear about the type of research programmes that could be... view more... (2004-07-07)
