The aim of this clinical trial is to evaluate the efficiency of two fertilization techniques used in Assisted Reproduction: conventional In Vitro fertilization (cIVF) and Intracytoplasmic Sperm Injection (ICSI), in terms of in-vitro and clinical results, in non-male infertility patients, comparing them in sibling oocytes. The main questions it aims to answer are: Does ICSI result in better fertilization rate, blastocyst rate or usable blastocyst rate? Does ICSI result in better pregnancy, clinical pregnancy and live birth rates? Researchers will compare cIVF to ICSI in sibling oocytes to assess if a technique offers better results. Participants undergoing an IVF/ICSI cycle will have their oocytes randomly divided in two groups: the oocytes from one group will be fertilized using cIVF and the oocytes from the other group using ICSI.
