Chromosome inversion is divided into pericentric inversion and paracentric inversion. Pericentric inversion of the heterochromatin region of chromosome 9-[inv (9), inv (9) (p11q13) or inv (9) (p12q13)] is the most prevalent pericentric inversion in the human karyotype. In the first IVF or ICSI cycle, couples with one pericentric inversion of chromosome 9 in one partner had satisfactory outcomes.
