Abstract

The cytological effects of the contraceptives Conovid E and Lyndiol were studied onAllium root tips. In the stronger concentrations Conovid E has a pronounced stathmokinetic effect, producing polyploidy, possibly aneuploidy, star metaphases, anaphase bridges. Lyndiol did not have any effect on metaphase, although anaphase irregularities were observed. The difference between the two substances is explained at least in part by the presence of an O=atom in the progesteron component of Conovid, which is not present in the progesteron component of Lyndiol.
