Child Follow-up in Women Treated With Conventional IVF or ICSI

Overview

To compare the physical, mental and motor development of babies born from pregnancy using ICSI technique and and conventional IVF in non-male factor infertile couples. Based on our previous RCT (NCT03428919), the non-male factor couples were randomly assigned to IVF or ICSI, which leads to the similarity in characteristics of these two groups. Hence, the result of analyzing these offsprings would be preciously valuable.

Over the past two decades, intracytoplasmic sperm injection (ICSI) indications have been extended and routinely applied to all cases of assisted reproductive techniques: unexplained infertility, poor-quality oocytes, low oocyte yeild, advanced marternal age, prior failed fertilization with conventional insemination, after in-vitro maturation of oocytes and for cases of cryopreserved oocytes (Practice Committees of the American Society for Reproductive Medicine, 2020). In 2004, fertilization using ICSI accounted for nearly 60% of all aspirations globally. In the Middle East, the number of ICSI cycles increased rapidly from 2000 (47.6%) to 2007 (65.2%), and reached 97.8% in the Middle East in 2007 (Ishihara et al, 2015). Another survey recorded in Europe in 2011, out of a total of 437,510 cycles of fresh embryo transfer, 68% of cycles were performed using ICSI techniques. In male infertility cases, the rate of implementation of ICSI increased from 76.3% to 93.3%. In particular, in cases of non-male-factor infertility, the incidence of ICSI also increased from 15.4% to 66.9%. From 2008-2012, of 494 907 treatment cycles, 74.6% used ICSI. In which, ICSI accounts for 92.9% of the cycle of male infertility and 64.5% of the cycle of non-male-factor infertility (Boulet, 2015). However, ICSI is an invasive technique that bypasses the natural barriers of fertilization. This has led to concern about an increase in the incidence of anomalies in ICSI-born babies as this technique is increasingly being used in all cases of contraception. In contrast, there are studies that have also compared IVF with ICSI and show that in the ICSI cycle, the incidence of multiple pregnancies and low birth weight infants is lower than that of IVF, although there is no difference in infant survival between the two groups (Boulet et al, 2015). In addition to the short-term outcomes, the investigators also have to consider the long-term maternal and neonatal outcomes. There is still not much evidence comparing the effects of the above methods, if any, on the psychomotor development in children. Therefore, the investigators decide to conduct a study to compare the physical, mental and motor development of babies born from pregnancy using ICSI technique and and conventional IVF in non-male factor infertile couples.
