The effect of growth hormone addition protocols to poor ovarian responders in <i>in vitro</i> fertilization cycles

Abstract

OBJECTIVE: In vitro fertilization failure (IVF) is high in women with poor ovarian response or non-responder. For this reason, the addition of adjuvant treatments to IVF protocols has come to the fore. We assessed to investi-gate the effects of adjuvant GH therapy initiated in the mid-luteal phase on IVF success in poor ovarian response or non-responder women. PATIENTS AND METHODS: A retrospective study was performed in 93 poor ovarian response or non-responder women from a single center. GH treatment was added (GH-plus group) in the mid-luteal phase of the previous menstrual cycle to 47 of the women who underwent con-trolled ovarian stimulation with the flexible antagonist protocol. 46 women, as another group, were applied to a flexible antagonist-only protocol (GH-free group). The IVF outcome results were evaluated and compared within the groups. RESULTS: The number of retrieved oocytes was statistically significantly higher in the GH-plus group (2.28 +/- 1.975) than in the GH-free group (1.24 +/- 1.728) (p=0.01). Although statistically in-significant (p=0.55), the clinical pregnancy rate was higher in the GH-plus group [(8/47), 17%] than in the GH-free group [(5/46, 11%]. The cancellation rate was statistically significantly higher in the GH-free group (65.2%) than in the GH-plus group (44.7%) (p=0.04). No oocyte retrieved cycle rate was higher in the GH-free group (56%) than in the GH-plus group (25%) (p=0.002). CONCLUSIONS: Adjuvant GH therapy administration to IVF protocol in the mid-luteal phase gives poor ovarian response or non-responder women a chance to have a baby.
