Women postpone motherhood because of their desire for personal and professional improvement. It is known that the quantity and quality of oocytes per cycle depends on the patient’s age. Success rates in assisted reproduction treatments decrease with age, especially after 40 years of age. Higher live birth rates are observed in younger women, and rates decrease significantly in older women due to decreased fertility and increased miscarriages. Therefore, age is crucial when assessing the possibility of a successful pregnancy through assisted reproductive treatments (ART). The indications to perform in vitro fertilization (IVF) with own ovules in women older than 40 years include starting as soon as possible highly complex procedures, good evaluation of ovarian reserve with antimüllerian hormone analysis (AMH) and antral follicle count (AFC) for genetic counseling, proposing IVF-intracytoplasmatic sperm injection (ICSI) before the age of 44 years, generating realistic expectations and informed consent, with own statistics. At REDLARA, of all IVF-ICSI procedures, 34% of patients are over 40 years old; preference is given to transfer blastocysts with preimplantation genetic testing for aneuploidy (PGT-A) to select euploid embryos. Success rates are low, even when they are pregnancy rates per embryo transfer in the group of women ≥ 40 years (18.2% without PGT, 42.7% with PGT in IMRCRP). It is recommended to bank ovules or embryos by performing multiple ovarian stimulations. A single embryo transfer should be chosen to avoid obstetric complications with multiple pregnancies in patients ≤ 40 years, because of the high risk due to age.
