Obesity
Conditions
Brief summary
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.
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.
Interventions
BEHAVIORALDiet and exercise
Total caloric intake aimed at maintaining a diet with\> 50% of the caloric content in the form of carbohydrates, less than 10% in the form of saturated fats and 20% from monounsaturated / polyunsaturated (if applicable, up to 25% fat monounsaturated), less than 300 mg / day of dietary cholesterol and about 1.0 g of protein / kg ideal body weight / day.

Inclusion criteria
* Women who want pregnancy. * Basal FSH levels ≤ 10 IU / l. * Infertility to justify treatment with IVF/ICSI. * Being included in a long protocol with GnRH agonist. * Presence of both ovaries and uterus able to support embryo implantation and pregnancy. * Body mass index (BMI) ≥ 30 kg/m2 and ≤ 35 kg/m2. * Absence of pregnancy before starting ovarian stimulation. * Having given their written consent.
Exclusion criteria
* Female age ≤ 18 years and ≥ 35 years. * Severe male factor not permit an IVF-ICSI with ejaculated sample. * Patients with low ovarian reserve (basal FSH levels ≥ 10 IU / l or lower antral follicle count to 6 follicles in both ovaries). * HIV seropositivity, HBV or HCV. * Clinically important disease. * Having frozen embryos from previous cycles of assisted reproduction. * Unexplained vaginal bleeding. * Poor response in previous IVF cycles with standard stimulation protocols * Any contraindication to become pregnant. * Known allergy to preparations of gonadotropins or its excipients. * High consumption of alcohol, drugs or psychotropic drugs. * Concurrent participation in another study. * Patients who have done previous cycles of IVF / ICSI without success
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pregnancy rate | 14 days after embryo transfer | Pregnancy rate by cycle |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Hyperstimulation rate | At luteal phase and first weeks of pregnancy | Number of patients with moderate or severe hyperstimulation |
| Fertility rate | 24 hours post pick up | Rate of mature oocytes fertilized by conventional IVF or ICSI |
| Mature oocytes | Pick up day | Number of total mature oocytes obtained after stimulation |
| Good quality embryos | Day 3 to 5 post pick up | Number of good quality embryos obtained (A and B) by patient |
| Abortion rate | First trimester of pregnancy | Number of non evolutive pregnancies during the first trimester |
| Live birth rate | Between 7 a 9 months after treatment | Amount of patients who finish the treatment with a live newborn |
| Cancellation rate | Durinf the stimulation in follicular phase | Stimulated Patients who fail to perform the follicular puncture |
Other
| Measure | Time frame | Description |
|---|---|---|
| Leptin, adiponectin, resistin, interleukin VI, TNF-α, visfatin, IGF1 and PAI I | During the stimulation phase | Study the relationship between obesity and measurable surrogate parameters the same as the products of secretion of fat (leptin, adiponectin, resistin, interleukin VI, TNF-α, visfatin, IGF1 and PAI I) or with inflammatory parameters results of an IVF cycle. |
