Scientist Makes Lesbian Mice Gives Birth without The Help of Male Mice (Photo)

Using gene editing and stem cells, researchers in China have helped mice of the same sex give birth without a father, but 2 mothers.

While this feat has been accomplished before with mouse moms, the new study marks the first time that pups from pairs of male mice were also carried to full term.

The technology is far from ready for the leap to humans.

Though mice pups born from two mothers appeared healthy, pups with two fathers died soon after birth.

Of the 12 born, just two survived more than 48 hours.

Still, the new study was recorded as an encouraging step toward a better understanding of the barriers that prevent such genetic coupling between individuals of the same sex.

The work also raises a slew of ethical questions among experts, with the health of future offspring being the primary concern.
