A study looked at kids born from frozen embryo transfers, fresh embryo transfers, and natural pregnancies to see if the way they were conceived affects their size at age 12. The research found that children from frozen embryo transfers tend to be slightly larger than those from fresh transfers or na
The study looks at how many embryos—one or two—are transferred during fresh IVF cycles when the embryos are at the cleavage stage. Researchers used a statistical method called propensity score matching to compare success rates and risks between the two groups. First, they gathered data from a large
Scientists wanted to see if certain markers in the uterus could help predict how well frozen embryo transfers would work. Specifically, they looked at BCL6 and SIRT1, two proteins that play a role in cell function. The study focused on the mid-luteal phase, a crucial time in the menstrual cycle for
