This study demonstrates that a daily dose of cetrorelix 0.2 mg is able to prevent premature LH surge.

In multifetal reduction to twin pregnancies, the maternal serum levels of inhibin A decrease to the level of twin pregnancies during the second trimester. Therefore, inhibin A may be effectively used as a marker for Down syndrome screening in cases of twin pregnancy following multifetal reduction.

Increasing the cetrorelix dosage from 0.125 to 0.250 mg/day when the follicular size is appropriate can prevent a prematureLH surge.

An unusual case of a heterotopic cervico-isthmic pregnancy after IVF treatment occurred in a 34-year-old woman. Transvaginal ultrasound-guided aspiration of the gestational sac for embryo reduction was safely used to manage the pregnancy and preserve the intrauterine fetus.
