Summary

Post-embryo transfer bed rest does not increase pregnancy success rates (PR). A randomized controlled trial found no significant difference in clinical or ongoing PR for women who rested versus those discharged immediately.

Area of Science:

  • Reproductive Medicine
  • In Vitro Fertilization (IVF)

Background:

  • Post-embryo transfer care protocols often include recommendations for bed rest.
  • The efficacy of bed rest in improving pregnancy rates after IVF is not well-established.

Purpose of the Study:

  • To investigate if a standardized period of bed rest following embryo transfer impacts pregnancy rates in women undergoing IVF.

Main Methods:

  • A randomized controlled trial was conducted at a university reproductive health clinic.
  • 164 IVF cycles were randomized: 30 minutes of bed rest versus immediate discharge.
  • Pregnancy rates were assessed clinically (fetal heartbeat) and ongoing (gestation beyond 11 weeks).

Main Results:

  • Clinical pregnancy rates were 50% in both the bed rest and immediate discharge groups.

  • Ongoing pregnancy rates were 46.3% in both groups.
  • No statistically significant difference was observed between the two interventions.

    • Conclusions:

    • A 30-minute period of bed rest after embryo transfer does not enhance pregnancy rates.
    • Current evidence suggests immediate discharge is as effective as bed rest post-embryo transfer.
