NCT00910390

Brief Summary

This randomized study compares three different freezing methods to store human in vitro fertilization (IVF) embryos: vitrification with two commercial kits or slow freezing. After information, all patients undergoing IVF treatment can be included in the study. If qualified, embryos at different developmental stages will be allocated between the three methods. At the end of the first year survival and developmental rates, and implantation and pregnancy rates will be analyzed in order to determine the best method.

Study Arms (3)

Slow Freezing

PLACEBO COMPARATOR

Standard freezing protocol (slow freezing) of preimplantation embryos

Other: Slow freezing

VIT-Irvine

EXPERIMENTAL

Vitrification with Irvine solution (rapid freezing) of preimplantation embryos

Other: VIT-Irvine

VIT-Vitrolife

EXPERIMENTAL

Vitrification (rapid freezing) with Vitrolife solution

Other: Vit-Vitrolife

Interventions

Embryos at different developmental stages will be frozen using a solution that contains propanediol and sucrose, individually placed in high security straws, cooled with a programmator and stored in liquid nitrogen.

Also known as: Home-made solutions, propanediol
Slow Freezing

Embryos at different developmental stages will be frozen using the vitrification solution according to the manufacturer's instructions, individually placed in high security vitrification devices and plunged directly in liquid nitrogen for storing.

Also known as: IRVINE, California, ethylene glycol, DMSO
VIT-Irvine

Embryos at different developmental stages will be frozen using the vitrification solution according to the manufacturer's instructions, individually placed in high security vitrification devices and plunged directly in liquid nitrogen for storing.

Also known as: VITROLIFE, Sweden, ethylene glycol, propanediol
