Follicular Flushing Using Double Lumen Needle Versus Direct Aspiration in Low Prognosis Patients According to the POSEIDON Criteria

This is a prospective, randomized, controlled clinical trial designed to evaluate whether follicular flushing increases the number of cumulus-oocyte complexes (COCs) retrieved compared to single aspiration in patients with poor ovarian response belonging to Poseidon groups 3 and 4. A total of 40 patients with poor ovarian response belonging to Poseidon groups 3 and 4 will be included. In each patient, one ovary will be randomized to the study technique (follicular flushing), and the other ovary will be randomized to the control technique (single aspiration).

Open, Non-comparative Pilot Study to Evaluate the Safety and Efficacy of Intraovarian Plasma Rich in Growth Factors (PRGF) in Patients With Low Ovarian Reserve

The use of plasma rich in growth factors (PRGF) improves ovarian reserve markers and IVF laboratory parameters in women with low ovarian reserve. Primary objective To compare ovarian reserve markers and IVF-ICSI laboratory results before and after PRGF infusion. Secondary Objectives * To compare pre- and post-treatment pregnancy rates. * To collect complications associated with the application of intraovarian PRGF. General Outline of the Study VISIT 1 * Patient Selection * Confirm that he/she has all the analyses and variables to be studied. * Signing of Informed Consent * Usual IVF protocol (1st IVF cycle) VISIT 2 * Instillation of intraovarian PRGF on the day of the puncture of the 1st IVF cycle in the FJD VISIT 3 * Analytical control at 4 weeks VISIT 4 * Analytical control at 8 weeks VISIT 5 * In case of failure to achieve gestation Start of 2nd cycle of IVF
