Brief Summary:
Aim of study: To compare the relationship between serum AMH and ovarian response for IVF with the GnRH antagonist protocol in patients who are carriers of FSH and/or LH receptor polymorphisms with those that are not.

Condition or disease
antimüllerian Hormone and Gonadotrophin Receptor Polymorphism as Predictors of Ovarian Response

Detailed Description:

Serum AMH has shown to have a high predictive capability of the ovarian response to stimulation for IVF. On the other hand, patients who are carriers of polymorphisms in the FSH and LH receptors, have shown to need higher doses of gonadotrophins for ovarian stimulation. The proportion of carriers has been described to be around 20% of the population. Nevertheless, the determination of these polymorphisms is not performed in routine practice. It is unknown if their presence affects to the relationship between serum AMH levels and ovarian response.

This is a prospective, single center, non-interventional, cohorts study.

Actual Study Completion Date : December 18, 2019

Group/Cohort
patients with FSH/LH polymorphisms
Infertile patients will undergo an ovarian stimulation with FSH and/or hMG. Doses will be chosen according to BMI, Antral follicle count, AMH and age.
patients without FSH/LH polymorphisms
Infertile patients will undergo an ovarian stimulation with FSH and/or hMG. Doses will be chosen according to BMI, Antral follicle count, AMH and age.



Primary Outcome Measures :
  1. Gonadotrophin receptor polymorphisms and ovarian response and AMH value [ Time Frame: 1 year ]
    To compare the relationship between serum AMH and ovarian response for IVF with the GnRH antagonist protocol in patients who are carriers of FSH and/or LH receptor polymorphisms with those that are not.


Secondary Outcome Measures :
  1. polymorphisms in the FSH receptor (FSHR) variant N680S [ Time Frame: 1 year ]
    To define the incidence of carriers of polymorphisms in the FSH receptor (FSHR) variant N680S (homozygous and heterozygous) among women undergoing ovarian stimulation for IVF.

  2. polymorphisms in the LH receptor (LHR) variant N312S [ Time Frame: 1 year ]
    To define the incidence of carriers of polymorphisms in the LH receptor (LHR) variant N312S (homozygous and heterozygous) among women undergoing ovarian stimulation for IVF.

  3. Doses of gonadotrophin needed and polymorphisms [ Time Frame: 1 year ]
    To analyse the doses of gonadotrophins needed for stimulation on each group of patients
