Cross-over Study to Prove Bioequivalence Between Two Oral Formulations of Levonorgestrel

A single dose, two treatments (Postday and Opxion), two periods, two sequences, crossover, randomized, prospective design was chosen with a washout of 21 days between the two study periods. Treatment groups were balanced with the same number of male healthy volunteers who were randomly assigned to the study drug administration sequences.
