In general, it is a very happy event for a couple to have twins, so many infertile couples try IVF twins. For young couples, their infertility is not serious and their uterus has a good environment for conception, they can try to have twins, but not everyone is suitable to have twins, whether they can have twins or not is based on the size of the uterus and the endometrium of the uterus in all aspects to decide, and twins are not recommended for women of advanced age. Are baby twins good? Having twins is a good thing, but there are many risks for both mother and baby. Mothers who are pregnant with twins and multiple babies are more likely to develop high blood pressure and diabetes during pregnancy, and may bleed more during labor, which is a high risk. And for the reborn child, the diseases formed by prematurity and congenital lung disease may follow the child for life, which not only increases the economic burden on the family, but also on society. Is it good to have twins with IVF? In general, the birth of a couple with twins is a very happy event, so much so that many infertile couples request their doctors to implant at least two embryos when they undergo IVF technology, as they want to have one more child through IVF. However, fertility experts believe that twin and multiple births brought about by assisted reproduction techniques should be prevented as much as possible. In medical terms, multiple births of medical origin are considered to be a failure of assisted reproduction, experts say. What are the chances of IVF twins The IVF technique uses ovulation promotion to obtain more eggs, embryo cases, and transfer 2 to 3 embryos to the uterus to complete conception. IVF with ovulation promotion has greatly improved the success rate of IVF, and after all these years of development, the technology is now quite mature. IVF without ovulation stimulating drugs is done by monitoring the follicles and serum hormones during the natural cycle and retrieving the eggs before ovulation is imminent and doing in vitro fertilization. The advantage of natural cycle egg retrieval is that it avoids stimulation of the ovaries by drugs, reduces patient costs and avoids multiple pregnancies, but the clinical pregnancy rate is much lower than using ovulation promotion, therefore, the vast majority of fertility centers currently use IVF under ovulation promotion cycles. What are the chances of IVF twins? It is easy to have twins with IVF The current global annual output rate of twins and multiples among newborns has reached 20% in some countries with high birth rates. Having twins is certainly a joyous occasion, but multiples are more risky than singletons, and this risk exists for both the mother and the child. Mothers of multiples are more likely to develop gestational syndromes such as diabetes and hypertension during pregnancy, and have a higher probability of postpartum hemorrhage, as well as being more prone to premature birth. Therefore, once a multiple pregnancy is detected, IVF patients must follow the advice of their fertility doctor to perform a reduction, which is mandatory for three or more pregnancies and recommended for twins.
