Can IVF choose twins?
IVF technology has brought hope to many infertile couples, so that people who cannot conceive naturally can become parents. However, for some people, they may wish to have twins to meet their family expectations and needs. So, can IVF choose twins? This article will elaborate on this from four aspects.
1. Does IVF technology support the selection of twins
IVF technology includes in vitro fertilization (IVF) and embryo transfer, which directly determine whether twins can be selected. During in vitro fertilization, surplus embryos can be frozen. If the patient wants to have twins at the same time, they can transfer two embryos to the mother at the same time in the embryo transfer stage to increase the chance of pregnancy. However, this also increases the risk of multiple pregnancy, which may lead to a higher incidence of complications.
In order to avoid the risk of multiple pregnancy as much as possible, some countries and hospitals have formulated some regulations, such as allowing multiple embryos to be transferred only under specific circumstances, and limiting the number of transfers. Therefore, IVF technology itself supports the selection of twins, but it needs to be carried out under the restrictions of laws and hospital policies.
2. Medical ethics and social factors
It is a complex problem whether the selection of twins is in line with medical ethics and social morality. On the one hand, twins may increase the burden of care and education for couples, which may affect the family's economic and social conditions. On the other hand, some couples may wish to have twins to meet their family wishes out of the expectation of sibling relationship.
Therefore, when choosing twins, doctors and hospitals should carefully evaluate the couple's motives, and provide advice and guidance to ensure that they make wise decisions. In addition, the society also needs further discussion and reflection to balance the relationship between individual choices and public interests.
3. Risk of multiple pregnancy
Selection of twins by IVF technology may increase the risk of multiple pregnancy. Multiple pregnancy is associated with a higher incidence of complications, including premature delivery, low birth weight, birth defects, etc. At the same time, it will also bring certain risks to the mother's health, such as uterine bleeding, hypertension, etc.
In order to reduce the risk of multiple pregnancy, some countries and hospitals have formulated policies and guidance to limit the number of embryo transfers and encourage single embryo transfers. This can reduce the incidence of multiple pregnancy and protect the health of mothers and infants.
4. Mental health of twins
Twin infants are different from singleton infants in many aspects. They may face higher competition and comparison, and may even have rejection and hostility. The mental health of twin infants also needs attention and monitoring.
Therefore, the choice of twins needs to consider the child's future development and happiness. Parents and society should provide good education, environment and support to help twins grow up healthily.
Summary
IVF technology itself supports the selection of twins, but it needs to be carried out under the restrictions of laws and hospital policies. The medical ethics and social factors in selecting twins need to be considered and evaluated. The risks of multiple pregnancy need to be paid attention to and managed. The mental health of twin infants also needs attention and support. Therefore, when selecting twins, it is necessary to comprehensively consider multiple factors to make the most appropriate decision.
