Examination of the rebound effect of biphasic oral contraceptives

Attempt has been made to induce ovulation with temporary Anteovin administration, that is with the rebound effect following the discontinuance of treatment in 34 women with anovulatory cycles who suffered from functional sterility. Ovulation could be induced in 9 cases and among the women whose cycles had become biphasic 3 became pregnant and 2 delivered normal healthy babies before closing the study. The results proved that rebound effect may be expected even following the use of Anteovin which is satisfactory from the aspect of a future fertility in women taking the tablet for cotraception.
