STUDY OF IN VITRO FERTILIZATION AND THE IMPACTS OF MATERNAL AGE

Abstract

The postponement of motherhood is an increasing phenomenon in contemporary societies, influenced by social, economic and professional factors. In this context, in vitro fertilization (IVF) has become one of the main alternatives for couples facing reproductive difficulties. However, advanced maternal age remains a determining factor for the success of the technique, as it directly impacts oocyte quality and quantity, fertilization rate, embryonic competence and pregnancy outcomes. This study aims to analyze the influence of maternal age on IVF results, based on scientific evidence. Articles from recognized databases such as SciELO, PubMed, Oxford Academic and BioMed Central were used as sources of data. Results show that women over 35 years old present a progressive reduction in ovarian reserve, lower pregnancy rates and higher obstetric risks, even when undergoing IVF. Strategies such as oocyte cryopreservation, preimplantation genetic testing (PGT-A) and personalized ovarian stimulation protocols are effective alternatives to mitigate the effects of reproductive aging. It is concluded that although IVF represents a significant advancement, maternal age remains the main biological limitation, making reproductive planning essential for better outcomes.
