| World Health Organization (WHO) | Lynestrenol, a synthetic progestogen, was introduced in the early1960s as a component in oral contraceptive preparations. In 1967, as a result ofnew regulations required by the United States Food and Drug Administration,lynestrenol was submitted to long-term toxicity studies and by the early 1970s itwas shown to be associated with an increased incidence of mammary tumours inbeagle bitches which led to its withdrawal by at least one regulatory authority.Subsequently the validity of the beagle bitch model as a predictor ofcarcinogenicity of steroid contraceptives has been contested by many nationalregulatory authorities and lynestrenol remains available in some countries forcontraceptive and other purposes.(Reference: (WHODI) WHO Drug Information, 1-3, 5-7, 1984) |
| Safety Profile | An experimental teratogen.Experimental reproductive effects. Human reproductiveeffects by ingestion and implant routes: menstrual cyclechanges or disorders, female fertility index, other fertilitychanges and effects on females. Questionable carcinoge |
