The scientists revealed today that the couples, who are making visits to IVF clinics for getting treated for infertility, are at the risk of delivering babies who are infertile too.

Such clinics use a radical male infertility treatment repeatedly without caring much about the health of the babies conceived by using such methods.

An Intracytoplasmic sperm injection is used for the procedure. In it, individual sperm cells are injected into an unfertilised egg to develop the chances of producing an embryo which can be implanted into the womb of a woman. It also brings with it the risk of multiple births as well as medical complications.

According to Andre Van Steirteghem, of the Brussels Free University Centre for Reproductive Medicine, the technique is very useful in treating infertile couples, but it should be opted only after a doctor recommends it.

About 3 million children have been conceived using this technique throughout the world. The use of ICSE has grown by leaps and bounds which led to half of all test-tube conceptions in Britain and two-thirds of the same in Europe.

Dr Van Steirteghem said, "The health of children has to be considered the most important outcome of artificial reproductive technology treatment. It's fair to say that overall these children do well [but] there a few more problems with these children".
