C. Albano et al., Avoidance of multiple pregnancies after ovulation induction by supernumerary preovulatory follicular reduction, FERT STERIL, 76(4), 2001, pp. 820-822
Objective: To evaluate the effect of supernumerary preovulatory follicular
reduction as an approach to avoid multiple pregnancies in ovulation inducti
on or superovulation cycles.
Design: Retrospective study.
Setting: Tertiary referral center.
Patient(s): In 26 cycles, 24 patients underwent ovulation induction or supe
rovulation with either clomiphene citrate or hMG.
Intervention(s): Selective follicle aspiration was performed before hCG adm
inistration.
Main Outcome Measure(s): Clinical pregnancy rate and numbers of multiple pr
egnancies.
Result(s): A mean number of 4.5 follicles with a diameter greater than or e
qual to 15 mm. and a mean number of 4.5 follicles with a diameter less than
or equal to 14 mm were observed before hCG administration. A mean number o
f 2.3 follicles with a diameter greater than or equal to 15 mm and a mean n
umber of 1.8 follicles with a diameter less than or equal to 14 nun were as
pirated before the hCG administration. Seven singleton pregnancies (26.9% p
er cycle) ensued from the treatment.
Conclusion(s): Aspiration of supernumerary follicles after ovulation induct
ion or superovulation seems to be a valid approach to avoid multiple pregna
ncies without affecting pregnancy rate. (Fertil Stetil(R) 2001;76: 820-2. (
