The Medical Board of California said it was necessary to revoke Dr. Michael Kamrava's license to protect the public. The revocation takes effect July 1.

The Beverly Hills fertility doctor has acknowledged implanting 12 embryos into Suleman prior to the pregnancy that produced her octuplets. It was six times the norm for a woman her age.

That was a mistake, according to the board.

``While the evidence did not establish (Kamrava) as a maverick or deviant physician, oblivious to standards of care in IVF practice, it certainly demonstrated that he did not exercise sound judgment in the transfer of twelve embryos to (Suleman),'' the board said in its 45-page decision.

Since Suleman's octuplets were born in January 2009, the medical community and public have puzzled over how a doctor could have implanted so many embryos into a patient and how the babies were carried to premature birth.

In practice, fertility doctors avoid mega-births, as high number multiple births are sometimes called, because the process can put the mother at risk for serious complications and death. Crowding in a mother's uterus could also result in premature birth, cerebral palsy, developmental delays or other health problems for the babies.

To date, Suleman's octuplets are the world's longest surviving set.

Kamrava's lawyer Henry Fenton did not return phone calls seeking comment.

With a tearful apology, Kamrava testified at his hearing last year that he implanted Suleman with 12 embryos because she consented to undergoing fetal reduction if too many of the babies became viable.

Kamrava said that months passed after the treatment, and he never heard from her, despite efforts to contact her. He says he only heard from Suleman again after the babies were born.

The state also found that Kamrava was negligent in the care of two other patients _  a major factor in the decision to revoke his license.

``This is not a one-patient case or a two-patient case; it is a three-patient case and the established causes of discipline include repeated negligent acts,'' the board decision reads.

Kamrava was found to have implanted seven embryos in a 48-year-old patient, resulting in quadruplets. One fetus died before birth.

Kamrava said at his hearing that he recommended four embryos be implanted, but he implanted seven because the patient insisted.

In another case, Kamrava went ahead with in vitro fertilization after tests detected atypical cells, which can indicate the presence of a tumor. The patient was later diagnosed with stage-three cancer and had to have her uterus and ovaries removed before undergoing chemotherapy.

Kamrava said he should have referred her to a gynecological oncologist but simultaneous to her treatment, news broke about Suleman's octuplets and he became too distracted to follow up the patient's care.

In February, a judge recommended the board put Kamrava on five years of probation, but the ultimate licensing decision belonged to the board. Citing negative publicity surrounding Suleman's case, the judge had said it was unlikely Kamrava would make similar mistakes again.

The board ``adamantly'' disagreed with that assessment, saying the doctor had already used bad press as an excuse for failing to care properly for the fertility patient who should have been referred to a cancer specialist.

``Accordingly, the board is not persuaded that relying on the public or the media to fulfill or supplement the board's public protection role is sound policy,'' the decision reads.
