E.2.1 | Main objective of the trial |
Study the difference in the number of oocytes obtained by performing ovarian stimulation in the follicular phase vs. Luteal phase in a population of patients with a suboptimal prior response. |
Estudiar la diferencia en el número de ovocitos obtenidos realizando la estimulación ovárica en fase folicular vs. fase lútea en una población de pacientes con respuesta previa subóptima. |
|
E.2.2 | Secondary objectives of the trial |
• To evaluate if there are differences between both groups in terms of duration of stimulation • To Study of the differences between both groups regarding the consumption of gonadotropins and the cost of treatment • To Evaluate if there are differences between both groups in the cancellation rate of the stimulation cycle • To Evaluate if there are differences between both groups regarding the metaphase stage oocyte rate II • To Evaluate if there are differences between both groups in the rate of survival in the thawing and rate of fertilization after microinjection. |
• Evaluar si hay diferencias entre ambos grupos en cuanto a duración de la estimulación • Estudio de las diferencias entre ambos grupos en cuanto al consumo de gonadotropinas y coste del tratamiento • Evaluar si hay diferencias entre ambos grupos en la tasa de cancelación del ciclo de estimulación • Evaluar si hay diferencias entre ambos grupos respecto a la tasa de ovocitos en estadio de metafase II • Evaluar si hay diferencias entre ambos grupos en la tasa de supervivencia en la descongelación y tasa de fertilización tras microinyección. |
