Two sets of sextuplets were born in Arizona and Minnesota last June 11 and 12.

Brianna Morrison, 24 and Jenny Masche, 32, mothers of the 2 sets of sextuplets gave birth to their children 10 hours apart. Both sought artificial methods of conceiving babies through fertility drugs and artificial insemination.

Morrisson gave birth to four boys and two girls only after 22 weeks. While Masche gave birth to three boys and three girls that were 10 weeks premature.

Doctors says that these occurrence would become more common, as more couples seek ways of conceiving babies through artificial means.
