Congress will leave in place a ban on genetically modified human embryos, despite a push to overturn it, Stat News reports.

Where it stands: Since 2015, Congress has effectively banned a procedure that combines genetic material from a mother, father and female donor.

A group of scientists, patient advocates and bioethicists are pushing for Washington to lift the ban on mitochondrial replacement therapy, a procedure that combines genetic material from a mother, father and female donor, Stat News reports.

The big picture: Advocates for the procedure say it helps women who carry genetic diseases have healthy children that are biologically related to them. Opponents cite safety, ethical and religious concerns.
