Abstract
The degree of cervical ripeness correlates with the ease of
induction and the duration of labor (Bishop, 1964). A score of
at least 6 is considered favorable and more likely to result in a
successful labor. Cervical ripening does not only occur as aresult
of uterine contractions but also due to an active ripening
process within the cervix.
Methods to ripen the unfavorable cervix include extraamniotic
balloon stretching, Jaminaria, prostaglandin E2 gel
and porcine relaxin (Rayburn and Russ, 1986). The ripening
process is probably controlled by the same hormones that play a
role in triggering uterine contractile activity, in particular prostaglandin
E2 (PGE2) (Garfield, 1987). Many double blind investigations
have demonstrated the value of PGE2 for cervical
ripening and induction oflabor (Rayburn, 1989). Cervical ripening
