Infertility treatment could be more
effective in the future, as scientists working at the University of Bristol
believe they have found the optimum number of embryos to implant during
assisted conception.
The team studied data from the UK Human Fertilisation and Embryology Authority
(HFEA) and found that the live birth rate with the transfer of two embryos is
higher than when only one is implanted.
However, the correlation between number and success does not continue
indefinitely.
"Transfer of three embryos did not increase the live birth rate over that
seen after transfer of two embryos, but was associated with an increased risk
of adverse perinatal outcomes," said the authors of the study, professor
Debbie Lawlor from the University of Bristol's School of Social and Community
Medicine and professor Scott Nelson from the University of Glasgow's Centre for
Population and Health Sciences.
The HFEA said a multiple birth is the biggest risk to those couples who are
undergoing IVF treatment.
