Abstract

To determine whether the short or long protocol for controlled ovarian hyperstimulation works better in older patients undergoing IVF. Controlled, randomized study. A single private IVF center. Two hundred twenty infertile women aged > or = 40 years undergoing IVF. At their first IVF cycle, the women were randomized into two study groups according to a computer-generated number sequence: 110 patients were treated with a long protocol, and the other 110 were treated with a short protocol for controlled ovarian hyperstimulation. Days of stimulation, E2 level at the day of hCG administration, amount of FSH administered, number of oocytes collected, number of embryos obtained, pregnancy rate, implantation rate. Patients treated with a long protocol showed a significantly higher number of oocytes retrieved, a higher number of embryos obtained, and a higher pregnancy rate, both for cycle and transfer, compared with the short-protocol patients. The other parameters evaluated did not show any statistically significant differences. Our study showed that the long protocol performed better than the short protocol in older women. Our findings demonstrated that flare-up in older women might be detrimental.
