The pregnancy rate of IVF-ET varies slightly from center to center, mainly because the age of the patients included in each center, the basal FSH value, and the number of previous IVFs all vary. And the main factors affecting IVF-ET success at a center include the age of the woman, response to the superovulation protocol, number of eggs obtained and treated, sperm quality, and number and quality of embryos transferred. Some patients are very worried after the transfer and think that being bedridden all day and night will help increase the pregnancy rate, when in fact studies have shown that being bedridden for 14 days after the transfer is no different from not being bedridden. Some people think that they can’t eat a lot of vegetables and fruits after transplantation, but there is no scientific basis for that either. Don’t be too nervous after transplantation, but a reasonable diet and a happy mood will be beneficial for pregnancy.
