Indore: With increasing cases of consanguineous marriage, i.e. marriage in blood relation, experts raised an alarm over increasing infertility and other disorders in conceiving among young couples.
“Most of us do not even recognise the pros and cons of such marriages but research and studies have proved that cousins who marry among themselves run double the risk of birth defects in their children. Genetic/chromosomally abnormalities are often found in such children that can have long term consequences,” IVF consultant of Manipal Fertility Dr Jyoti Karande said.
Warning the increasing trend of getting married to blood relations, Dr Karande said that assessing the consequence of consanguineous against non-consanguineous marriages in health and disease, several scientific studies have shown that consanguinity leads to death of infants before, during or immediately after birth, increased incidence of birth defects, genetic diseases including blinding disorders, blood cancer (acute lymphocytic leukaemia), breathing problems for children at birth (apnea), increased susceptibility to disease etc.
“Babies born out of such wedlock could have a multiplicity of congenital problems including heart problems, still births, lung issues, nervous disorders and other genetic abnormality like Down syndrome and others. The problem in such close relative marriages surfaces when one of the partners carries a defect in any of the genes associated with some form of illness,” she added.
Talking about the reasons of genetical disorders Dr Karande said, “When you marry within the community with one who may also have such a family defect, the child inherits two copies of this faulty gene and thus has the defect. But when you marry outside the community, you bring in genes from a much larger gene pool and the odds that the child will inherit the problem reduce remarkably.”
Dr Karande also stated that number of such cases has been increasing in the city as well as in the state as 8-10 couple are approaching them every month.
