What this trial studies

This clinical trial evaluates the effectiveness and safety of preimplantation genetic testing for aneuploidy (PGT-A) in women aged 37 to 41 years who are undergoing fertility treatments. Conducted across multiple fertility clinics in Denmark and Spain, the study aims to determine if PGT-A can improve pregnancy outcomes in this age group. Participants will be randomly assigned to receive either standard care or the PGT-A intervention during their IVF/ICSI cycles. The trial will assess the impact of genetic testing on embryo selection and overall fertility success rates.

Who should consider this trial

Good fit: Ideal candidates for this study are women aged 37-41 years with a male partner or those undergoing fertility treatment without a partner, who meet specific hormonal criteria.

Not a fit: Patients with severe endometriosis, significant thyroid disease, or those requiring specific sperm retrieval techniques may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could enhance the chances of successful pregnancies for women in this age group facing infertility.

How similar studies have performed: Previous studies have shown promising results with preimplantation genetic testing, indicating potential benefits in improving embryo selection and pregnancy outcomes.

Eligibility criteria

Show full inclusion / exclusion criteria
Inclusion Criteria:

* Women aged 37-41 years with a male partner, a female partner og undergoing fertility with no partner.
* Anti Müllerian Hormone (AMH) ≥6.28 pmol/L (AMH should be measured no more than one year prior to study inclusion). The optimal is to use the Elecsys® Assay. If other assays are used this should be reported to the investigator and the AMH cut-off level may appropriately be changed so that it corresponds to the cut-off used in the Elecsys® Assay.
* IVF/ICSI cycle number 1-5 (previous IVF/ICSI cycles will not count if the woman is recruited after an IVF/ICSI/FET-delivery).

Exclusion Criteria:

* PGT-SR or PGT-M.
* Testicular sperm aspiration (TESA), testicular sperm extraction (TESE), micro-TESE (or cryopreserved sperm from these procedures).
* Males with severely compromised semen quality (\<1 million progressively motile sperm cells following gradient centrifugation).
* Endometriosis stage three or four.
* Women with severe thyroid disease (women can be included if they have normal thyroid levels on relevant medication).
* Severe co-morbidity; diabetes mellitus type 1 (DM1), Mb Crohn or Colitis ulcerosa, systemic lupus erythematosus (SLE), HIV, Hepatitis B/C, or dysregulated thyroid disease.
* ≥2 previous ART treatment without blastocyst formation.
