Older IVF: Advantages and Disadvantages of Single vs Twin
With the progress of modern medicine, more and more couples choose IVF to achieve their fertility aspirations. However, in the process of selecting in vitro fertilization, an important question is whether to choose singleton or twins. This article will discuss the advantages and disadvantages of singleton and twins in older IVF from many aspects.
1. Pregnancy risk
The biggest difference between multiple pregnancies is risk. In IVF, twins are often produced by simultaneous transfer of multiple embryos. The risk of twin pregnancy is higher than that of singleton pregnancy. First of all, multiple pregnancy increases the risk of maternal pregnancy induced hypertension and diabetes. Secondly, the preterm birth rate of twins is high, which may lead to low birth weight and other related complications. In addition, twin pregnancy also increases the risk of twin to twin communication syndrome and early placental abruption.
However, single pregnancy is not without risks. Although the risk of singleton pregnancy is low, women's older childbearing itself has increased the probability of pregnancy complications, such as pre eclampsia and placental dysfunction. Even single pregnancy, if there are other potential health problems, it still needs special attention and careful treatment.
2. Pregnancy success rate
The choice of singletons or twins also has a direct impact on the success rate of IVF. The success rate of singleton pregnancy is usually higher, because each embryo has more opportunities to successfully implant into the uterine wall. On the other hand, although twin pregnancy can increase the chance of successful implantation of at least one embryo, the success rate may be low due to competition between embryos.
In addition, twin pregnancy also increases the risk of early abortion. If multiple embryos are successfully implanted, the selectivity of multiple pregnancy may be reduced. Therefore, when considering the pregnancy success rate, it is necessary to comprehensively consider the difference between single and twin pregnancies.
3. Twin rearing challenges
Once the pregnancy is successful, twin rearing will face greater challenges. Twins need parents to invest more time and energy, and may increase the financial burden. The competition and struggle between twins may also lead to disharmony in the family environment. In addition, there may be differences in the individual development of twins, which requires parents to adopt different education and training methods.
In contrast, single pregnancy is easier to manage and care for. Parents can better concentrate on taking care of a child and provide him with more comprehensive care and education.
4. Psychological and emotional influences
Whether choosing single or twin pregnancy, couples will be accompanied by a variety of psychological and emotional effects. For some infertile couples, they may be excited and satisfied with the success of IVF. However, for some couples who have experienced multiple failures of IVF or other difficulties, choosing single or twin babies will become a more complex decision.
No matter which way they choose, couples should understand and accept its positive and negative effects. They can make decisions by consulting professional doctors, communicating with other couples with similar experiences, and their own values and lifestyles.
summary
Single and twin pregnancies of older IVF infants have their own advantages and disadvantages. Single pregnancy has low risk, high success rate and relatively easy rearing. However, twin pregnancy increases the risk, the success rate may be low, and parenting needs to face greater challenges. Couples should make choices based on their personal circumstances and values, and fully understand and accept the impact of the selected way.
