Un estudio analizó la edad biológica de más de 1.700 participantes utilizando seis relojes epigenéticos diferentes. Los resultados mostraban que cada embarazo individual reportado por una mujer se correlacionaba con un envejecimiento biológico adicional de dos a tres meses. Estos efectos persistían incluso cuando se tenían en cuenta el estatus socioeconómico, el tabaquismo, la variación genética y la urbanidad del entorno de los participantes. El estudio se publica en PNAS. 

A study published in the journal PLOS Medicine concludes that the development and academic outcomes of girls and boys conceived with in vitro fertilisation (IVF) are no different from those of children conceived naturally. The analysis is based on data from two national assessments in Australia, including more than 585,000 children born between 2005 and 2014 (more than 11,000 conceived by IVF). The first assessment measured the physical and emotional and cognitive health of children aged 4-6 years; the second focused on the numeracy and verbal skills of schoolchildren aged 7-9 years.
