E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
The reproductive capacity of women depends on two factors: the number of follicles in the ovaries and the quality of oocytes within those follicles. Premature ovarian failure (POF) and poor ovarian response represent two challenges to ovarian stimulation protocols used in assisted reproduction. Currently, treatment of POF is extremely difficult. Classically, the number of oocytes is predefined at birth with no new gametes to be developed along the life of a woman. |
La capacidad reproductiva de una mujer depende del número d e folículos y de la calidad de los ovocitos dentro de los mismos. El fallo ovárico prematuro representa un reto en los protocolos de estimulación ovárica dentro del contexto de los tratamientos de reproducción asistida. Clásicamente, se ha considerado que una mujer nace con una dotación folicular y ovocitaria predeterminada y que a lo largo de la vida de la misma no se generan nuevos ovocitos. |

E.1.1.1 | Medical condition in easily understood language |
Autologus platelet-rich plasma (PRP) has been used in many medical conditions, including POP. But, after more than 15 years of clinical use of this therapy, no randomized trials have been designed. |
El tratamiento mediante plasma enriquecido en proteínas se ha utilizado en muy diferentes áreas de la medicina, pero no existen estudios adecuadamente diseñados en los casos de fallo ovárico. |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
Increase the number of available oocytes and their quality in patients with low ovarian response after a controlled ovarian stimulation procedure by activating quiescent primary follicles by the action of endogenous growth factors. This will allow to recover more oocytes and of higher quality, as well as reduce the number of stimulations in this type of patients. |
Aumentar el número de ovocitos disponibles y su calidad en pacientes con baja respuesta ovárica tras un procedimiento de estimulación ovárica controlada mediante la activación de folículos primordiales quiescentes por acción de factores de crecimiento endógenos. Esto permitirá recuperar más ovocitos y de mayor calidad, así como reducir el número de estimulaciones en este tipo de pacientes. |
|
E.2.2 | Secondary objectives of the trial |
Increase knowledge about the mechanisms of action of growth factors on the initial ovarian reserve of the patient and the activation of quiescent primordial follicles. Determine the effect of the dose and concentration of growth factors on the functional ovarian reserve pool. Evaluate the effect of growth factors on oocyte quality and subsequently on the embryo in its different stages of development. Evaluate the increase in the number of oocytes available in patients treated with growth factors after a new controlled ovarian stimulation procedure. Develop a therapeutic tool for patients with low ovarian response with which to reduce the number of cycles of controlled ovarian stimulation during ART. Reduce the number of stimulations necessary to achieve a certain number of oocytes. Improve oocyte quality and success rates of ART in patients with low ovarian response. |
Incrementar el conocimiento sobre los mecanismos de acción de factores de crecimiento sobre la reserva ovárica inicial de la paciente y la activación de folículos primordiales quiescentes. Determinar el efecto de las dosis y concentración de los factores de crecimiento sobre el pool de reserva ovárica funcional. Evaluar el efecto de los factores de crecimiento sobre la calidad ovocitaria y sobre el embrión en sus diferentes estadios. Evaluar el aumento en el núm. de ovocitos disponibles en las pacientes tratadas con factores de crecimiento tras un nuevo procedimiento de estimulación ovárica controlada. Desarrollar una herramienta terapéutica destinada a pacientes con baja respuesta ovárica con la que reducir el núm de ciclos de estimulación ovárica controlada. Reducir el núm. de estimulaciones necesario para conseguir un núm. determinado de ovocitos. Mejorar calidad de los ovocitos y tasas de éxito de los TRA en pacientes con baja respuesta ovárica. |
