E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the effect on the number of mature oocytes obtained after the follicular puncture depending on the stimulation protocol applied: -Stimulation protocol A (experimental): controlled ovarian stimulation using corifollitropin alfa -Stimulation protocol B (control): controlled ovarian stimulation using recombinant FSH and highly purified HMG |
Evaluar el efecto en el número de ovocitos maduros que se recuperan tras la punción folicular en función del protocolo de estimulación aplicado: - Patrón de estimulación A (experimental): estimulación ovárica controlada con corifolitropina alfa. - Patrón de estimulación B (control): estimulación ovárica controlada con FSH recombinante y HMG ultrapurificada. |
|
E.2.2 | Secondary objectives of the trial |
To evaluate the following parameters depending on the stimulation protocol applied (stimulation protocol A vs stimulation protocol B): - Total number of oocytes obtained after the follicular puncture - Number of stimulation days - Number of subcutaneous injection days - Total gonadotropin doses - Symptomatology - Patient perception of the stimulation treatment |
Evaluar los siguientes parámetros en función del patrón de estimulación aplicado (patrón de estimulación A frente a patrón de estimulación B): - Número de ovocitos totales recuperados tras la punción - Días de estimulación - Días de inyecciones subcutáneas - Dosis totales de gonadotropinas - Sintomatología - Percepción del tratamiento de estimulación por parte de la paciente |

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
Patients will be included in this trial when: -They must go through at least two stimulation cycles. -They are low responders to ovarian stimulation according to the Bologna criteria. -They accept voluntarily to participate in the trial signing an informed consent form. According to the Bologna criteria, at least two of the following three features must be present to be considered low responder: (i) Advanced maternal age (?40 years) or any other risk factor for poor response; (ii) A previous poor response (?3 oocytes with a conventional stimulation protocol); (iii) An abnormal ovarian reserve test (i.e. Antral Follicular Count 5?7 < follicles or Anti-Mullerian Hormone value < 0.5?1.1 ng/ml). |
Serán incluidas en el estudio aquellas pacientes que: -Vayan a someterse a un mínimo de dos ciclos de estimulación. -Sean bajas respondedoras de acuerdo a los criterios de Bolonia. -Acepten voluntariamente participar en el estudio, firmando el consentimiento informado. Según los criterios de Bolonia, al menos dos de las siguientes características deben estar presentes en una paciente para ser considerada baja respondedora:
?Edad materna avanzada (? 40 años en el momento de la firma del consentimiento) o cualquier otro factor de riesgo para ser baja respondedora ?Baja respuesta previa (? 3 ovocitos con un protocolo de estimulación convencional). ?Test de reserva ovárica con resultados anormales: recuento de folículos antrales (AFC) < 5-7 folículos; o concentración de hormona antimulleriana (AMH) en sangre < 0.5-1.1 ng/ml). |
|
E.4 | Principal exclusion criteria |
-Not fullfilling the inclusion criteria. -Not being able to sign the informed consent form. |
-No cumplir alguno de los criterios de inclusión. -No estar en condiciones de firmar el consentimiento informado aceptando la participación en el estudio. |
