The difference between IVF babies and naturally conceived babies is only in the location of fertilization. In IVF, fertilization of the egg and sperm occurs in a laboratory environment, and then the embryo is transferred to the mother’s womb. In contrast, in natural pregnancy, fertilization happens naturally inside the mother’s body.
The difference regarding the genetic content between IVF children and naturally conceived children
Regarding the genetic content, it is important to note that in both types of pregnancies—whether fertilization occurs inside the body or in a laboratory—the genetic material comes from the parents and there is no difference. The methods of infertility treatment do not increase the risk of fetal abnormalities, and advancements in embryo preservation techniques through freezing have increased the likelihood of successful fertilization per stimulated ovulation cycle. As a result, the first children born from frozen embryos in Iran are now about 15 years old, and studies in this group have shown that the risk of fetal abnormalities has not increased. Consequently, the difference between IVF babies and naturally conceived babies lies not in their genetic content but in the method of their formation and fertilization.
The difference in intelligence quotient (IQ) between infants conceived naturally and through IVF
You may wonder whether there is a difference in the intelligence quotient (IQ) of IVF babies compared to those conceived naturally. Numerous studies have been conducted to determine the differences between children born through IVF and those conceived naturally. It has been established that there is no significant difference in the IQ of children born through IVF and those born through natural conception. In both cases, the infants carry genetic content from their parents, whether conceived naturally or through IVF.
The difference in miscarriage rates between natural pregnancy and IVF
The risk of miscarriage in pregnancies resulting from IVF treatment is slightly higher compared to natural pregnancies. This risk is not related to the fertility treatment methods themselves but rather to the underlying infertility and the patient’s ability to conceive. However, if the conditions for embryo formation and fertilization are good, as well as the quality of the embryo being well-controlled, the incidence of miscarriage will be lower.
Conclusion
All in all, there are no fundamental differences between children conceived through IVF and those conceived naturally. They are similar in terms of growth, development, physical and mental health, and abilities. The only minor differences include a higher likelihood of multiple births in IVF, small differences in birth weight, and a slightly increased risk of congenital abnormalities in some IVF cases, which can be managed with genetic counseling. The most important point is that both methods of conception can lead to the birth of healthy and happy babies.
