Experts say the figures point to the responsibility of drugs used to increase the chances of pregnancy for the high numbers of multiple pregnancies, twins.The data revealed the UK Office for National Statistics that since 2001 the multiple birth rate rose by 8.8%.
Despite official policies that limit the birth of the twins, has recorded an increase in fertility clinics triplets rates, while at the same time data show the power fertilization and embryo decline in the number of British twins in IVF clinics, which means that the increase caused by the drugs stimulate the ovaries.
The multiple births a great danger to the mother because of the increased risk of health complications, and increase the likelihood of disability in embryos.
Said Dr. Jacob behind consultant gynecologist at the unit pregnancy Hospital Jay and St. Thomas, the unregulated use of drugs activate the ovaries is responsible for this rise, doctors prosecutors and consultants in hospitals prescribe these drugs excessively, leading to increased cases of multiple pregnancies.
But other factors may play a role in increasing the incidence of twins, including travel a lot of women abroad for treatment where no specific controls for doping ovaries and they received fertility treatment there, and increase the rate of pregnancy in women over the age of forty who rises have the possibility of multiple pregnancy, in addition to planting more of Jenin in the process of in vitro fertilization.Vitro fertilization or "test-tube babies" is a technique used to overcome some of the problems that prevent pregnancy, such as poor man's sperm count or low numbers, and the presence of uterine problems in women, such as blockage of the fallopian tubes.And are in the IVF technique to extract egg from a woman's uterus and fertilizing in the external environment and then re-injected into the uterus to attach themselves to Bbtanth and grow up to become an embryo. Usually doctors resort to vaccinate more than one egg to increase the probability of success of the operation if it fails one of the eggs fertilized, and multiple pregnancy occurs when the success of more than one egg.
Since 2009 Britain has taken a policy of encouraging women to grow one egg in each fertilization attempt, which led to a steady decline in cases of multiple pregnancies from 26.6% in 2008 to 20.1% in 2011.
In half of the cases of multiple pregnancy increases the risk of complications such as pre-eclampsia in the mother and child's cerebral palsy, also brings the infant mortality rate of twins five times.
He called back to the establishment of new recommendations governing the use of drugs stimulate the ovaries which reflects positively on the health of mother and child.Source: The Daily Telegraph
