Comparison of two media for sequential culture after IVF and ICSI shows no differences in pregnancy rates: a randomized trial.

Background: Optimal culture conditions are crucial for embryonic development and blastocyst formation after in vitro fertilization (IVF) or Intracytoplasmic sperm injection (ICSI). A prospective randomized trial was carried out to compare the effects of two different sequential media (Vitrolife and MediCult) on embryo development and implantation.

Material/methods: 176 couples were included in this prospective randomized study.
