Scripps research scientists identify infertility molecule
Scientists at The Scripps Research Institute are reporting that mice created to lack a certain type of molecule known as an LPA receptor have fertility problems, which suggests that these receptors play a major role in conception. In the latest issue of the journal Nature, the scientists detail how mice that lack LPA receptors, which normally appear on the surface of cells in a mouse's wo...New Discovery May Help Doctors Treat Infertility
New research suggests that medications commonly referred to as fertility drugs may be ineffective for women who lack a gene called the estrogen receptor beta. The study showed that fertility drugs did not improve ovulation rates in mice that were genetically engineered to lack estrogen receptor beta. The estrogen receptor beta is one of two estrogen receptor proteins which mediate the effects of...Absence of critical protein linked to infertility
The absence of a key protein may lead to infertility. Researchers at the University of Illinois at Urbana-Champaign report that experiments involving mice -- to be detailed in the Proceedings of the National Academy of Sciences -- indicate that the transcription factor protein C/EBPb must be present in the uterus for pregnancy to occur. The study appears online this week at the PNAS Web si...Injection may prevent infertility in men receiving cancer chemotherapy
It may be possible to protect the testes of cancer patients against the loss of fertility caused by chemotherapy, a scientist told the 22nd annual conference of the European Society of Human Reproduction and Embryology in Prague, Czech Republic on Tuesday 20 June 2006. Mr. Alon Carmely from Bar-Ilan University, Ramat Gan, Israel, said that his work showed for the first time that the injection o...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 today (Monday). Dr Iraj Amiri, embryology laboratory director at the IVF Centre, Fatemieh Hospital, Hamadan, Iran, said: "In recent years nitric oxide (NO) has been recognised...Infertility linked to lawn chemicals by Marshfield Clinic researcher
Marshfield, Wis. Low-dose exposures to agricultural and lawn care pesticides may cause injury to developing embryos before a pregnancy is even noticed, according to a , and bein...Male infertility in relation to cancer
Researhers from Britain examining the relationship between increasing rates of testicular cancer and decreasing sperm quality, have concluded men who have infertility problems have an increased risk of developing cancer. As reported in the issue of the British Medical Journal (BMJ), the study found a strong association between men with infertility problems and the subsequent risk of...Male infertility in relation to pesticide
Exposure to pesticides and solvents can further lower fertility among infertile men, a new report suggests.The study shows these chemicals may worsen the effect of pre-existing genetic or medical risk factors for infertility. The authors stress the findings should be treated with caution because they involved a selected population of infertile men, from a productive farming region in A...Infertility in relation with virus
German scientists reveal that a virus is possibly resposible for infertility.The virus is called adeno-associated virus (AAV) and was found in samples of testicular tissue taken from men whose semen was abnormal. The virus was found in these men far more frequently than in those with normal semen. Dr Jorg Schlehofer, from the Deutsches Krebsforschungszentrum in Heidelberg, which condu...How to repeal male infertility?
Researchers from the Hopkins University say that they may one day be able to reverse some cases of male infertility. The announcement is based on findings from an animal study that show infertile male mice treated with gene therapy are able to go on to produce offspring.// According to researchers, up to 30 percent of couples worldwide are infertile. Between 20 percent and 40 percent...Knowledge Of Infertility Gets New Inputs
Women who may lack a gene called estrogen receptor beta and not react to medications that can cure infertility.// In a research funded by National Institute of Environmental Health Sciences reported that the gene called estrogen receptor beta plays an important role in moving the egg outside the ovary to be fertilized. If women are lacking in this particular gene, which is found otherw...
