A clinical team Nurture Fertility in Nottingham have shown that in vitro fertilization is little better. In fact, the implantation of an embryo with another weaker lowers by 27% the chances that the pregnancy is successful. A very high probability, if you think that about 1 out of 4 embryo is probably too weak to develop.

Researchers have observed about 1,472 embryos implanted in women of all ages five days after fertilization. They analyzed the survival rate of embryos implanted alone, compared with those implanted with another less strong. The possibility to develop the first group were found to be far higher.

Scientists speculate that the body is concentrated weaker embryo, trying to expel him to put an end to the pregnancy. This has consequences also healthy embryo, which undergoes in turn the body's hostile environment. It would be for this reason that the embryos installations in torque would have a lower success rate of 27%, with respect to those instead implanted alone.

The team also analyzed the success rate of pairs of embryos that are both healthy. Even in these cases, it was less than that of embryos implanted individually. Researchers suspect that the body always tends to tararsi embryo with less chance of success. This process would compromise the healthiest embryo chance, even where the two embryos would have a chance to develop, if implanted alone.

The study concludes that for most adult women is best to proceed with an implant the desire, perhaps accompanying it with appropriate methods of prenatal screening

Anastassia Ontuoi, 67, became the oldest surrogate mother in the world. He has indeed lent the uterus to her daughter, who had conceded seven spontaneous abortions and that doctors had said they would never be able to conceive. The baby was born six weeks premature and by caesarean section. Although she weighed just 1.2 kg was fine.

Constatina was 43 years old and had a long and painful list of miscarriages. After yet another attempt failed, the mother had proposed to be her surrogate mother. A crazy proposal is the second woman is according to doctors. Dr. Constantinos Pantos has however supported the decision, and the two women followed throughout the process.

The choice of the woman was risky for her and the baby. The higher the age of the mother, in fact, more are the chances of running into conditions such as diabetes and high blood pressure. also increase the risk of miscarriage and complications during childbirth. Nevertheless, Anastassia Ontuoi went on their separate ways.
According to international registries, Ms. Ontuoi is now the oldest woman to have done as surrogate mother. Before her there was Carmen Bousada Lara, who had given birth to twins in the early 2000 and died of cancer in 2009.

A research of the Autonomous University of Barcelona reveals that pregnancy changes not only the body, but also the head of a woman. Hormonal changes affect the brain from a physical point of view, even reducing the volume of some regions. According to the study, just then an MRI to see if a woman has had children.

The researchers subjected 25 women to magnetic resonance imaging before, during and after the first pregnancy. They then compared the results with the MRIs of 19 men just become father of 17 childless men and 20 women who had never given birth.

The analyzed men showed no change. Pregnant women have instead shown a reduction in brain regions linked to the ability to attribute mental states. This can be associated with a greater difficulty in building a representation of thoughts, feelings, and of its intentions and the others. The resonances have also expressed an increased neuronal activity, which makes pregnant women more susceptible to images of infants.

Research has documented the conditions of women in the following years at first pregnancy. It was found that the structural changes will hold for two years, which allows to recognize the magnetic resonance of a woman who has given birth. But it is not yet clear the reason for these changes.

According to the researchers, there are several possible causes for the alterations to the brain structure. A could be a reduction of synapses, or in the number of glial cells. Another explanation brings into play the amount of blood that reaches the brain. What is clear is that hormonal surges and physical changes also lead to important neuronal changes. In all likelihood, each change has the function of preparing the woman to motherhood.

To check the health of the unborn child can undergo several examinations of prenatal screening, including the fetal DNA testing.

Several studies have already proven the importance of proper intake of vitamin D during pregnancy. The deficiency can lead to the development of malformations in the fetus, as well as diseases that sometimes manifest themselves only in adulthood.

An Australian study has found a link between vitamin D deficiency during pregnancy and autism. It seems that a vitamin deficiency in the first 20 weeks of gestation increases the risk of neurological damage in children.

Researchers at the Brain Institute at the University of Queensland, along with those of the Erasmus Medical Centre, analyzed the blood samples of 4200 mothers and their babies. They then separated the samples with less than 25 nmol / L of vitamin D, belonging to subjects with a deficiency of the substance. From observations it showed that a vitamin D deficiency in the mother is relatable to a higher rate of problems in neurological development. This means that, where necessary, it is advisable to take supplements that allow you to align the values ​​of vitamin D than normal.

Before this study, it was already known the role of vitamin D in the development of bones and nervous system. Beyond the diseases detectable with prenatal screening, more research they had connected the onset deficits of schizophrenia in predisposed individuals.
