E.1 Medical condition or disease under investigation |
E.1.1 | Medical condition(s) being investigated |
In this project, we propose the performance of a comparative study of different patterns of gestagenic coverage in in vitro fertilization (IVF) cycles with deferred transfer of genetically selected blastocysts. To do this, in the context of an IVF procedure, a cycle will be carried out with ovarian stimulation, with subsequent oocyte induction and retrieval (as is done routinely and according to protocol). |
Planteamos en el presente proyecto la realización de une estudio comparativo de diferentes pautas de cobertura gestagénica en ciclos de fecundación in vitro (FIV) con transferencia diferida de blastocistos genéticamente seleccionados. Para ello, se procederá, en el contexto de un procedimiento de FIV, a la realización de un ciclo es estimulación ovárica, con posterior inducción y recuperación ovocitaria (tal como se realiza de forma rutinaria y protocolizada). |

E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
To evaluate the efficacy in terms of evolutionary pregnancy of the transfer of genetically selected embryos based on the different gestagenic preparation protocols described. |
Evaluar la eficacia en términos de embarazo evolutivo de la transferencia de embriones genéticamente seleccionados en función de los diferentes protocolos de preparación gestagénica descritos. |
|
E.2.2 | Secondary objectives of the trial |
1. Assess the relationship between plasma levels of progesterone and endometrial thickness at the time of embryo transfer. 2. Assess the relationship between plasma levels of progesterone and endometrial pattern at the time of embryo transfer. 3. Assess the relationship between plasma levels of progesterone and route of administration (subcutaneous vs. Vaginal) on the day of B-HCG determination. 4. Assess the relationship between plasma levels of progesterone and ongoing pregnancy. 5. Assess the relationship between different parameters (age, BMI, number of oocytes obtained, number of developed blastocysts, percentage of euploid blastocysts) with evolutionary pregnancy rates. 6. Establish a hormonal coverage protocol with diagnostic and prognostic criteria for the future of assisted reproduction. |
1. Valorar la relación entre niveles plasmáticos de progesterona y grosor endometrial en el momento de la transferencia embrionaria. 2. Valorar la relación entre niveles plasmáticos de progesterona y patrón endometrial en el momento de la transferencia embrionaria. 3. Valorar la relación entre niveles plasmáticos de progesterona y vía de administración (subcutánea vs. Vaginal) el día de la determinación de B-HCG. 4. Valorar la relación entre niveles plasmáticos de progesterona y embarazo evolutivo. 5. Valorar la relación entre diferentes parámetros (edad, IMC, número de ovocitos obtenidos, número de blastocistos desarrollados, porcentaje de blastocistos euploides) con las tasas de embarazo evolutivo. 6. Establecer un protocolo de cobertura hormonal con criterios diagnósticos y pronósticos cara al futuro de la reproducción asistida. |
