A recent Swedish study has revealed that it is riskier for the mother and babies in case an In-Vitro-Fertilization-IVF procedure results in twin conceptions as compared to two singletons using the same procedure twice.
Multiple births by themselves come with extra concerns and risks. Although most fertility clinics have stopped implanting more than one embryo in IVF procedures , the debate on whether it is bad to have twins using IVF for desperate couples is still on.
Dr. Lynn Westphal , Women's' Health and Fertility Specialist at the Stanford University Medical Center, California said that many women suffering infertility for prolonged periods consider it bonus a to conceive twins using IVF procedure. Dr.Antonina Sazonova from Sahlgrenska University Hospital, Gothenburg led the study.
She and her team analyzed data colleted about fresh and frozen embryo transfers done at the IVF Clinics in Sweden between 2002 and 2006. Records included 991 women who delivered twins after double embryo transfer and 921 mothers who delivered two babies through two separate IVF procedures.
The team reported that 47 percent twin babies were born prematurely and 39 percent had low birth weight as compared to seven percent single babies born prematurely and less than five percent having low birth weight. Both, twin babies and their mothers had complications compared to single babies and their mothers.
The twin babies were prone to having breathing complications, jaundice or sepsis while twin –babies' mothers were two to three times more likely to have preeclampsia or high blood pressure , protein traces in their urine or four times more likely to require C-Section as compared to mothers who had single babies.
But there was no difference in twin or single babies in their chances of having severe malfunction or other life-threatening health problems. Westphal and her colleagues have since been counseling women to have single embryo-transplants especially if the parents are younger and having better fertility.
Keeping the cost of the procedure in mind, there could still be fewer takers for undergoing transplants twice especially if they were bearing the cost of the treatment.
