Controlled <scp>O</scp>varian <scp>H</scp>yper‐stimulation during <scp>IVF</scp> treatment does not increase the risk of preterm delivery compared to the transfer of frozen–thawed embryos in a natural cycle

While a woman's response to COH was weakly negatively correlated with gestation at delivery, this relationship was not of major clinical importance as the rate of preterm delivery and the median gestation at delivery were not significantly different between pregnancies resulting from fresh or FETs in our study cohort.
