Introduction  . .  some genes from babies conceived by means of IVF show a gene expression pattern that is different from naturally conceived children (Katari et al., 2009). . .  this mechanism could put children conceived by means of assisted reproduction treatment (ART) at a greater risk of diseases, such as diabetes and obesity, later in life.
Epigenetic deregulation already received increasing attention as a possible common cause of adverse ART outcomes, since the incidence of disorders that involve imprinted genes, especially the Beckwith–Wiedemann syndrome (BWS), is often reported to be increased in the offspring (Amor and Halliday, 2008, et al).
Conclusions . . ART can induce epigenetic variation that might be transmitted to the next generation. 
Key words, assisted reproduction,  epigenetics,  human,  genomic imprinting,  transgenerational epigenetic inheritance.
