Philosopher opposes 'rhythm method'

A British philosopher at the London School of Economics is drawing criticism from abortion opponents by opposing the "rhythm method," a report says.

The New York Times said Luc Bovens argues in the Journal of Medical Ethics that couples who use the rhythm method to avoid pregnancy may be more at risk of producing underdeveloped embryos.

The rhythm method refers to the practice of couples preventing pregnancy by avoiding sex during the woman's most fertile time of the month. If this is correct, he writes, "millions of rhythm method cycles per year globally depend for their success on massive embryonic death," the Times said.

Bovens asserts that those concerned about early embryonic death should be just as worried about the rhythm method as they would be over other forms of contraception.

Bovens's comments have drawn controversy in the United States and Britain from abortion opponents who advocate the rhythm method, or what is commonly known as natural family planning, the Times said.

Fertility experts say that although there are implications to its validity, there is little evidence to support Bovens's assumption.
