Data from three independently conducted epidemiological studies
have raised the problem of thromboembolic risks associated with combination oral
contraceptives containing desogestrel or gestodene (so-called third generation
oral contraceptives) in comparison with the same type of risk associated with the
levonorgestrel-containing oral contraceptives (so-called second generation
contraceptives). There are differences between countries in the evaluation of risks
associated with different combination oral contraceptives. There is no plausible
biological explanation for the differences between the two groups of oral
contraceptives; however, inherent biases cannot be excluded. Thus the matter
remains open.
