Saltillo, Mexico - According to the country's main television news broadcaster, a Mexican woman identified as Karla Vanessa Perez is pregnant with nine babies - 6 girls and 3 boys.

Perez, whose age was not given, is currently being treated at a hospital in the city of Saltillo, state capital of the northeastern state of Coahuila where she lives. She had fertility treatment leading to the multiple pregnancy.

State-owned news agency Notimex also reported the pregnancy, saying Perez was due to give birth on May 20th. "It's very early to think of names for the babies," she said in an interview, "first I hope that everything goes well."

A successful delivery of nonuplets would be one of the highest multiple births ever recorded. In 2009, Nadya Suleman gave birth to eight babies - six boys and two girls. At the time they were called the longest surviving set of octuplets in US history. In 2011, Dr. Michael Kamrava, the fertility doctor who implanted Suleman with 12 embryos had his license revoked by the medical board of California.

Fertility doctors performing in vitro fertilization have been urged to limit the number of embryos they implant to one or two, in order to reduce the risk of pre-term birth and increase infant survival. Recent research found that babies conceived through fertility treatments are more likely to have a birth defect than babies born without technological intervention.
