Should single embryo transfer be used in patients with any kind of infertility factor? Preliminary outcomes.

Objective: Multiple embryos have been transferred to compensate for low implantation rates, which in turn, increase the likelihood of multiple pregnancies. Despite the publication of clinical guidelines and a reduction in the number of embryos transferred, double embryo transfer still is the most common practice. There is no clear evidence of who should receive the single embryo transfer (SET), and it is more commonly indicated for patients of good prognosis.

The impact of balanced reciprocal translocation - 46,XX,t(7;17) (p13;q24) probably involving the SOX9 gene in the in vitro fertilization with own oocytes evaluated by preimplantation genetic testing or donated oocytes.

Preimplantation genetic testing (PGT) for in vitro fertilization (IVF) - also known as PGT for Structural Rearrangements (PGT-SR) - has emerged as an option for at-risk couples carrying balanced translocations. The female in the couple featured in this case report is a carrier of a balanced reciprocal translocation who underwent IVF. PGT showed all her embryos were aneuploid.
