In the UK, begin the tests "silicon womb" for IVF

British independent biopharmaceutical company with CARE Fertility begins clinical trials 'Silicon womb' for in-vitro fertilization (IVF) was developed. It is believed that the new device is to improve the viability of the fetus, and the chances of a successful conception of a child, according to the magazine New Scientist. The unit of the Swiss company Anecova developed a perforated silicone capsule length of five millimeters. The embryo of the "tube" in the laboratory, inside the capsule, the closed ends placed. After the "Silicon uterus" placed in the uterus of the patient and fixed by a flexible wire and yarn are shown in the ends of the cervix. After 1-5 days, the capsule is taken, opened, and the selection of experts make the best quality embryos for subsequent transplantation into the uterus of the patient. Currently for IVF embryos cultured in a test tube in a laboratory until they are in the womb transplant patients. In this case, produce every few hours specialists spare ground for embryo - add the ingredients and remove the harmful byproducts of metabolism. According to the creators, "The use of 'Silicon womb allowing embryos in an environment close to nature that will grow to improve their chances of survival. In a small pilot study in Belgium, scientists were encouraging but inconclusive results. In the British study, 40 women. From each of them will receive 8.12 of eggs used for fertilization "in vitro". Half the embryos are cultured in the laboratory, and the rest will be placed in the "Silicon uterus' which is in the uterus of patients in two to four days. Then experts compare the embryos cultured on both types, the presence of test of congenital defects, the best embryos are transplanted into the uterus of the patient. study leader Simon Fishel (Simon Fishel) expects that the embryos of "silicon womb" to be more viable. In the future, this will reduce the number of eggs for IVF necessary , reducing the risk of complications arising from hormonal stimulation of the ovaries. Meanwhile, a number of British experts were skeptical about the idea of a "silicon womb". particular put Lawrence Shaw (Laurence Shaw) of the London fertility clinics Bridge Centre, that in vivo first seven days of life holds no embryo in the womb, but moved to the fallopian tube. Accordingly occurs development in different conditions. Braud supported scientist Peter (Peter Braude) from King's College London, who, two days after the implantation of the embryo conception in the womb of a maximum of 30% of cases lasts said.
