About this study

The purpose of this study is to determine the impact of diet and physical exercise program on pregnancy rate and live birth in obese women who undergo an IVF cycle.

Read the detailed description

The objective of this study is showing that obesity significantly affects the in vitro fertilization cycles lowering the reproductive capacity. The study is been performed in Hospital de la Santa Creu i Sant Pau and Fundació Puigvert of Barcelona. Patients recluted are obese women with sterility problems that require in vitro fertilization (IVF) with a body mass index BMI between 30-35. It´s a randomised study in which half of the patients undergo to a 6 weeks program of diet and exercice. We will analyse the response to ovaric stimulation, the results of the egg retrieval (ovocyte number and quality), rates of fecundation, embryo implantation and clinical gestation.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Pregnancy rate

    Pregnancy rate by cycle

    Measured: 14 days after embryo transfer

Secondary outcomes (7)
  1. Hyperstimulation rate

    Number of patients with moderate or severe hyperstimulation

    Measured: At luteal phase and first weeks of pregnancy

  2. Fertility rate

    Rate of mature oocytes fertilized by conventional IVF or ICSI

    Measured: 24 hours post pick up

  3. Mature oocytes

    Number of total mature oocytes obtained after stimulation

    Measured: Pick up day

  4. Cancellation rate

    Stimulated Patients who fail to perform the follicular puncture

    Measured: Durinf the stimulation in follicular phase

  5. Good quality embryos

    Number of good quality embryos obtained (A and B) by patient

    Measured: Day 3 to 5 post pick up

  6. Abortion rate

    Number of non evolutive pregnancies during the first trimester

    Measured: First trimester of pregnancy

  7. Live birth rate

    Amount of patients who finish the treatment with a live newborn

    Measured: Between 7 a 9 months after treatment
