Hello Doctor, I recently had a karyotyping test done, and my report shows a female karyotype (46,XX) in all analyzed cells. However, it also mentions a variation in the heterochromatic region of the short arm of chromosome 15 (15p+), which I understand may be a benign polymorphism. I am currently undergoing fertility/IVF treatment, and my IGS (embryo transfer procedure) is scheduled for tomorrow. I would like to understand: Is this chromosomal variation clinically significant? Can this affect embryo quality, implantation, or increase miscarriage risk? Is PGT-A testing recommended in my case? Is further test required? Is donor egg needed
