Muscle Strength and Cardiorespiratory Fitness in Minors Conceived through Assisted Reproductive Technologies: Insights from the Munich heARTerY Study

Background: More than 200,000 children are conceived through assisted reproductive technologies (ART) every year in Europe. In the literature, an altered vascular function in the ART offspring is discussed. Within the general population, elevated vascular morbidity is associated with lower cardiorespiratory fitness. This study aimed to evaluate whether minors conceived through ART show reduced muscle strength and cardiorespiratory fitness compared to spontaneously conceived peers.
