Embryo implantation is achieved upon successful interaction between a fertilized egg and receptive endometrium and is mediated by spatiotemporal expression of implantation-associated molecules including leukemia inhibitory factor (LIF). Here we demonstrate, in mice, that LIF knockdown via a photoactivatable CRISPRCas9 gene editing system and illumination with a light-emitting diode can spatiotemporally disrupt fertility. This system enables dissection of spatiotemporal molecular mechanisms associated with embryo implantation and provides a therapeutic strategy for temporal control of reproductive functions in vivo.
