Study: Threatened miscarriages complicate 20% of all pregnancies

Dr Kaltum Adam, an honorary clinical research fellow at St Mary's Hospital in Manchester (UK), told the annual meeting of the European Society for Human Reproduction and Embryology that around 20% of all pregnancies were complicated by threatened miscarriage, and up to 20% of these would miscarry.

Cleavage stage embryo with aneuploidy can undergo genetic normalisation process

Professor William G. Kearns told the annual meeting of the European Society of Human Reproduction and Embryology that a three-day-old embryo with an incorrect number of chromosomes was capable of undergoing "a dynamic process of genetic normalisation" so that by day five, when it had developed to the blastocyst stage, it had become euploid, with the correct number of chromosomes.

Early childbearing impedes education among women

In almost every country, women with more education have fewer children. But does education reduce childbearing, or does childbearing get in the way of education, or both? New research by Joel E. Cohen and colleagues in Norway found that, at least among a population of Norwegian women, childbearing impeded education more than education impeded childbearing.

New model may help reduce multiple pregnancies in women

Dr Jan Holte told the annual meeting of the European Society for Human Reproduction and Embryology, that if this model were to be applied in all fertility clinics, it had the potential to reduce the twin rates to the level of just under two percent seen in the normal population. Already, another four clinics have started to use the model.

New insight into oocyte chromosome abnormalities

Ovarian stimulation undertaken by women of advanced maternal age receiving fertility treatment may be disrupting the normal pattern of meiosis - a critical process of chromosome duplication followed by two specialised cell divisions in the production of oocytes and sperm - and leading to abnormalities of chromosome copy numbers that result in IVF failure, pregnancy loss or, more rarely, the birth of affected children with conditions such as Down's syndrome, which is caused by the inheritance of three copies of chromosome 21.

Girl's Book Project delivers critical information about puberty and health

The onset of puberty is a critical moment for reaching girls with health messages and information, and the stakes are particularly high in countries where the HIV/AIDS epidemic rages and where threats to female reproductive health abound. Yet to date, the healthcare community in low-resource countries has tended to neglect this opportunity and instead concentrate efforts on young women who are older and of reproductive age.

BPA “de-masculinizes” male mice: Study

Laboratory studies have shown that male mice who are exposed in the womb to bisphenol A, or BPA, a chemical compound found in some hard plastics and can linings, appear to be less masculine and less attractive to females once they mature. This raises controversies that human boys could be similarly affected. The findings were published Monday on the website of the journal Proceedings of the National Academy of Sciences.

Healthy diet, antioxidants, critical nutrients and activities may provide the foundation to youthful living

As the baby boomer generation continues to increase in age, so does its passion to remain youthful, both inside and out. Beating the clock is now a multi-faceted, science-driven industry. From its age-old quests to find the elixir of life, to modern exploration of how microcellular activity contributes to metabolic breakdown, scientific research continues to advance its goals to enhance bodily energy, vigour and performance, and fade or stall the visible signs of aging.

Overactive mTOR can result in serious disruption of kidney filter in diabetes patients

Diabetes mellitus is one of the most common secondary diseases in modern society. And because it is on the rise, it is also one of the greatest challenges facing medicine today. Diabetes patients do not die as a direct result of the increase in blood sugar, but from the long-term complications of their disease, in which the increase in blood sugar causes damage to blood vessels and organs.
