Women who opt IVF method to have baby should be aware that will more likely to have baby boy than a girl, discovered Australian researchers. They believe that IVF process can affect the sex ratio. It could be due to male embryos which can somehow be better prepared to survive in the process.
Another assisted reproductive method compared with standard IVF is known as ICSI (intracytoplasmic sperm injection) in which sperms are directly injected into the eggs because normally sperm may be too weak to infiltrate the egg naturally. They also considered how precisely when the embryo was implanted into the womb.
They observed almost fourteen thousand babies born to women who underwent the transfer of a single embryo, reported the study published in the British Journal of Obstetrics and Gynecology. The overall male ratio of babies born was more than fifty percent. Nevertheless, the study found specific IVF systems altered the equilibrium.
When compared with IVF process, ICSI fashioned a lower ratio of male babies and standard IVF a higher ratio. In IVF egg is taken from the woman and mixed with male sperm in the lab for fertilization, before implanting the womb. While in ICSI process a single sperm is chosen for injection and fertilization.
This process inclines towards the odds of having a baby girl. In IVF where the embryo was implanted after five days, more than fifty per cent of births were boys. But when ICSI embryos were implanted at two to three days, les than fifty percent of babies were boys as compared to girls.
The use of IVF help childless couples may have wellbeing and social insinuations, said Professor Philip Steer, BJOG’s editor-in-chief. Researchers studied all live births following fertility treatment in clinics in Australia and New Zealand between 2002 and 2006.
