Brief Summary
Since preimplantation genetic testing (PGT) is being more frequently requested from patients as women pursue infertility treatments at an advanced age with a poorer prognosis, sometimes physicians are compelled to perform several stimulation cycles to obtain more eggs and, consequently, a greater number of biopsied embryos. Hence, the idea of carrying out this study arises as an attempt to optimize each menstrual cycle to the maximum. It is believed that the double stimulation (DuoStim) protocol could be an alternative for this group of patients, allowing to obtain a larger number of oocytes in a shorter period, thus, increasing the number of biopsied embryos and possibly decreasing the interval to achieve a successful pregnancy. The investigators aim to evaluate the potential usefulness of the DuoStim protocol for patients desiring to obtain oocytes as soon as possible. Using PGT, the investigators will compare the rate of euploid embryos per cycle in patients undergoing DuoStim protocol versus patients undergoing two conventional controlled ovarian hyperstimulation in consecutive cycles. Patients will include women with advanced age and poor response. This is a unicentric, prospective, randomized, non-blind, parallel-group controlled phase IV clinical study. The investigators hypothesize that the rate of euploid embryos per cycle is similar in the DuoStim group compared to the group undergoing two conventional controlled ovarian hyperstimulation in consecutive cycles. Furthermore the investigators will evaluate if there are differences regarding the number of total oocytes obtained, the number of mature oocytes, the number of biopsied blastocysts and the MitoScore index of the available euploid embryos.

Study Arms (2)
DuoStim
EXPERIMENTALTwo controlled ovarian stimulation within the same menstrual cycle using human menopausal gonadotropin 225 IU/day subcutaneously, GnRH antagonist in a dose of 0.25 mg/day subcutaneously and 0.2 mg of GnRH analog to induce oocyte maturation. It will be followed by ovarian puncture, oocyte isolation, intracytoplasmic sperm injection and trophectoderm biopsy at the blastocyst stage. Preimplantation genetic test and MitoScore will be performed in all the embryos prior to the embryo transfer. At this step embryos will be frozen to wait for the results. Chromossomally normal embryos will be thawed and transferred to the uterus in a deferred cycle. A pregnancy test will be performed when appropriate.

Trophectoderm biopsy is the process of removing few cells from an in vitro fertilization embryo.
The cells removed from an in vitro fertilization embryo during the trophectoderm biopsy will be used to assess the mitochondrial DNA content as a viability indicator in the euploid embryos.
ICSI is an in vitro fertilization procedure in which a single sperm is injected directly into an oocyte.
Egg retrieval is a simple procedure. It is performed in an operating room for safety reasons. It is performed vaginally and involves aspirating the follicular fluid through a thin needle. Embryologists then retrieve from this fluid the eggs that have matured during stimulation. It lasts for 5 to 15 minutes, and a mild sedative is administered to prevent any kind of pain during the procedure.
The cells removed from an in vitro fertilization embryo during the trophectoderm biopsy will be tested for chromosomal normalcy before transferring the embryo to the uterus.
Embryo transfer refers to a step in the process of assisted reproduction in which embryos are placed into the uterus
A pregnancy test is used to determine whether a woman is pregnant.
Embryo freezing is a method for cryopreserving embryos.
Embryo thawing is the procedure to recover previously frozen embryos prior to an embryo transfer.
