The behavior of follicle cysts formed after long-acting gonadotropin-releasing hormone analog administration in patients with polycystic ovarian syndrome

Outcomes from ovarian hyperstimulation following the sole administration of gonadotrophin-releasing hormone agonist in the context of in vitro fertilization: report of two cases and review of the literature

OBJECTIVE

To report the outcomes from two cases of ovarian stimulation following the sole administration of gonadotrophin-releasing hormone agonist (GnRHa) in the context of in vitro fertilization (IVF).

DESIGN

A case study was conducted.

SETTING

National Referral Unit of Reproductive Medicine.

PATIENTS

Two infertile women undergoing IVF participated in the study.

INTERVENTIONS

Controlled ovarian hyperstimulation using a long protocol. GnRHa (Buserelin) was started in the luteal phase, in a dose of 600 µg/day, for 12 days.

MAIN OUTCOME MEASURES

Number of retrieved oocytes, fertilization rate, number of embryos transferred, implantation rate, ongoing pregnancy, and live birth.

RESULTS

Both women underwent egg retrieval and transfer of good quality embryos. One of them conceived and recently gave birth to a healthy full-term baby.

CONCLUSIONS

The ovarian hyperstimulation after the sole administration of GnRHa is a rare condition. Oocyte retrieval may be a reasonable treatment under these circumstances instead of cycle cancellation. As far as it is known, this is the third case reported of a live birth following the sole administration of GnRHa in the context of IVF.
