Abstract/OtherAbstract:
OBJECTIVE: To analyze the impact of LH administration on cycle outcome in ovarian stimulation with GnRH antagonists.
DESIGN: Randomized, open-label, controlled trial performed in two age subgroups. Recombinant (r) FSH versus rFSH + rLH administration was compared.
SETTING: University-affiliated private infertility clinic.
PATIENT(S): Up to 35 years old (n = 380) and aged 36 to 39 years (n = 340), undergoing their first or second IVF cycle.
INTERVENTION(S): Recombinant LH administration since stimulation day 1.
MAIN OUTCOME MEASURE(S): Implantation rate, ongoing pregnancy rate.
RESULT(S): In the young population, implantation rates were similar: 27.8% versus 28.6%, odds ratio (OR) 1.03 (95% confidence interval [CI] 0.73-1.47), as was the ongoing pregnancy rate per started cycle: 37.4% versus 37.4%, OR 1.0 (95% CI 0.66-1.52). In older patients, the implantation rate was significantly higher in the rFSH + rLH group: 26.7% versus 18.6%, OR 1.56 (95% CI 1.04-2.33). Ongoing pregnancy rates per started cycle were 33.5% versus 25.3%, OR 1.49 (95% CI 0.93-2.38).
CONCLUSION(S): Recombinant LH administration significantly increased the implantation rate in patients aged 36 to 39 years. A clinically relevant better ongoing pregnancy rate per started cycle was observed, although the difference was not statistically significant. Patients younger than 36 years do not obtain any benefit from rLH administration.
