Experimental: Polar Body Biopsy
PB biopsy (PBB) will be performed between 9 and 12 hours after ICSI using laser or the mechanical procedure. PB1 and PB2 will be removed simultaneously (both at the same time) and transferred to different tubes for the chromosomal analysis.

- To improve live birth rates. [ Time Frame: up to 1 year after birth ]This trial has two primary aims among women with advanced maternal age (1) to improve live birth rates and (2) to assess the prediction value of having no euploid oocytes in future ART cycles.

Ages Eligible for Study: | 36 Years to 41 Years (Adult) |
Sexes Eligible for Study: | Female |
Accepts Healthy Volunteers: | No |
Inclusion Criteria:
- infertility as an indication for IVF or ICSI;
- patients between their 36th and 41st birthdays (at time of signing ICF i.e. max 40years and 364days at the day of signing the informed consent);
- BMI range 18 to 30 kgs per m2;
- patients prepared to accept transfer of up to two embryos;
- absence of any type of genetic abnormality in the patient's personal and family history;
- normal karyotype (optional)
Exclusion Criteria:
- treatment involving donor oocytes (donor sperm is allowed subject to local practice and regulations and provided karyotype of the sperm donor is available and normal);
- menstrual irregularity (<24 and >35 days);
- three or more previous failed IVF or ICSI cycles, with the present partner. (Definition of a failed cycle: 'absence of a clinical pregnancy relating to a treatment with embryo transfer resulting from oocyte retrieval for the current intended pregnancy and with the current partner; the transfers include transfers of fresh and frozen within this treatment; clinical pregnancy is defined as the presence of a gestational sac at the earliest ultrasound and includes early clinical miscarriage, late miscarriage and clinically confirmed extrauterine pregnancy, and excludes preclinical miscarriage (biochemical pregnancy); -
- three or more clinical miscarriages;
- poor response in any previous cycle;
- low ovarian reserve (At least one of the following two features must be present: (1) a previous poor ovarian response (≤ 3 oocytes with a conventional stimulation 119 protocol); (2) an abnormal ovarian reserve test (i.e. AFC < 5 follicles or AMH < 0,5 ng/mL)* (adapted from Ferraretti et al., 2011);
- cycles requiring surgical sperm recovery procedures;
- total asthenozoospermia and/or globozoospermia.
- any type of genetic abnormality or family history of genetic abnormality in subject or partner
