LOS ANGELES (Reuters) - The doctor who implanted 14 embryos into California’s so-called “Octomom” should have his medical license revoked for ignoring standard guidelines, a lawyer for the state’s medical board said on Monday.

Beverly Hills fertility specialist Dr. Michael Kamrava should also have referred Nadya Suleman to a mental health specialist when she came to him saying she wanted more babies to add to her brood of six, according to an official complaint by the California medical board.

Suleman, an unemployed single mother, gave birth to octuplets in January 2009, making international headlines when it became clear that she already had six young children.

The California medical board later complained that Kamrava’s treatment of Suleman had endangered her health and that of her babies. Kamrava implanted 14 embryos into Suleman over 12 years.

The negligence complaint also alleges that Kamrava improperly implanted another patient, aged 48, with seven embryos. This patient was not named.

Monday’s hearing before an administrative law judge could lead to the loss of Kamrava’s medical license. The judge will later make a recommendation to the California Board of Medical Examiners on whether the license should be suspended or revoked.

Kamrava’s attorney said on Monday his client strictly followed guidelines for fertilization and showed great concern for his patients.

Suleman, now 35, was dubbed “Octomom” after public joy over the live birth of only the second full set of octuplets in the United States turned sour when her personal circumstances were revealed in the media.

Suleman has made multiple TV and media appearances but has struggled to keep up mortgage payments on her home.
