  Purpose

The present study aims to elucidate if there is a metabolomic profile alteration in the embryos of obese women in order to understand if the reduced implantation rate observed in these patients is directly related to this factor. Furthermore, the investigators seek to establish if there is any difference between obese women with Polycystic Ovary Syndrome (PCO) and without PCO. The investigators compare these metabolomic profile embryos with embryos of egg-donation programme.

Primary Outcome Measures:
  • Metabolic profile of culture media of Day 3 embryos [ Time Frame: 3 days ] [ Designated as safety issue: No ]
    Determine differences in the metabolomic profile of the culture media of day 3 embryos, obtained after in vitro fertilization, according to the presence of obesity associated or not with polycystic ovary syndrome.


Enrollment: 28

Groups/Cohorts Assigned Interventions
CONTROL
Fertile women (egg-donors)
Other: Culture medium metabolomic analysis

During the embryo transfer at day 3, the investigators keep and freeze a small drop of the culture medium of each embryo transferred. Each drop of culture medium will have a volume of 40-50 microliters, before freezing is spun at 10.000 rps to avoid any possible contamination.

The frozen media culture is analyzed for the metabolomic profile.

WITH PCO
Obese women with Polycystic Ovarian Syndrome
Other: Culture medium metabolomic analysis

During the embryo transfer at day 3, the investigators keep and freeze a small drop of the culture medium of each embryo transferred. Each drop of culture medium will have a volume of 40-50 microliters, before freezing is spun at 10.000 rps to avoid any possible contamination.

The frozen media culture is analyzed for the metabolomic profile.

NO PCO
Obese women without Polycystic Ovarian Syndrome
Other: Culture medium metabolomic analysis

During the embryo transfer at day 3, the investigators keep and freeze a small drop of the culture medium of each embryo transferred. Each drop of culture medium will have a volume of 40-50 microliters, before freezing is spun at 10.000 rps to avoid any possible contamination.

Study Population

45 women divided into three groups: A)15 Obese women without Polycystic Ovarian Syndrome: BMI > 30 kg/m2 , age < 38 years old, normal basal hormonal profile (FSH, LH, estradiol, testosterone, androstenedione, insulin, SHBG, glucose, AMH, and antral follicle count(> 5 FA for each ovary), menses every 25-35 days.

B)15 Obese women with Polycystic Ovarian Syndrome: BMI > 30 kg/m2, age < 38 years old, basal hormonal profile with or without hyperandrogenism and ultrasound ovary aspect of PCO.

C)15 Fertile women (egg-donors): BMI 20-24.9 kg/m2. All the patients have normal uterine conditions, are not smokers, without endometriosis or hidrosalpinx. All the male partners have sperm parameters: count(> 5 mill/ml,15% motility,> 0% normal morphology)and BMI < 28 kg/m2.
