USE
Lynestrenol, a synthetic progestogen, was introduced in the early
1960s as a component in oral contraceptive preparations. In 1967, as a result of
new regulations required by the United States Food and Drug Administration,
lynestrenol was submitted to long-term toxicity studies and by the early 1970s it
was shown to be associated with an increased incidence of mammary tumours in
beagle bitches which led to its withdrawal by at least one regulatory authority.
Subsequently the validity of the beagle bitch model as a predictor of
carcinogenicity of steroid contraceptives has been contested by many national
regulatory authorities and lynestrenol remains available in some countries for
contraceptive and other purposes.
