IVF has no advantages or disadvantages like the intelligence of a naturally conceived child. In IVF, a woman’s eggs and a man’s sperm are screened, and special treatment is required to select high-quality eggs and sperm to be combined and cultured, and later transplanted into the uterine cavity. Therefore, most IVF babies are not very different from naturally conceived babies, and are usually well developed and have normal IQs. If the growth and development of blastocysts in the uterine cavity is affected by various pathogenic factors, such as environmental factors, genetic factors, drug factors, etc., which cause abnormal growth and development of the fetus, it may be accompanied by a decrease in IQ, but IVF itself will not lead to IQ problems.
