ABSTRACT
BACKGROUND:
This study evaluated the predictive value of serum and follicular fluid (FF) concentrations of anti-Müllerian hormone (AMH) with respect to treatment outcome variables in an IVF cycle.METHODS:
A retrospective analysis was performed with data from 731 normogonadotrophic women undergoing controlled ovarian stimulation after stimulation with highly purified menotrophin (HP-hMG) or rFSH following a long GnRH agonist protocol.RESULTS:
In both treatment groups, the serum AMH concentration at the start of the stimulation was significantly (P < 0.001) positively correlated with the serum levels of estradiol (HP-hMG r = 0.45; rFSH r = 0.55), androstenedione (HP-hMG r = 0.50; rFSH 0.49) and total testosterone (HP-hMG r = 0.40; rFSH r = 0.36) at the end of the stimulation as well as the number of oocytes retrieved (HP-hMG r = 0.48; rFSH r = 0.62), the AMH concentration in FF (HP-hMG r = 0.55; rFSH 0.61) and the serum progesterone concentration (HP-hMG r = 0.39; rFSH r = 0.50) at oocyte retrieval. For both treatments, serum AMH at the start of the stimulation was a good predictor of the need to increase or decrease the gonadotrophin dose on stimulation day 6 and of ovarian response below (<7 oocytes) or above (>15 oocytes) the target. No significant relationships were observed between serum AMH and embryo quality or ongoing pregnancy.CONCLUSION:
The serum AMH concentration at the start of the stimulation in IVF patients down-regulated with GnRH agonist in the long protocol revealed a positive relationship with ovarian response to gonadotrophins in terms of oocytes retrieved and accompanying endocrine response. AMH is a good predictor of the need for gonadotrophin-dose adjustment on stimulation day 6 for patients with a fixed starting dose, but a poor predictor of embryo quality and pregnancy chances in individual patients.
