ABSTRACT
PURPOSE:
The incidence of chromosomal polymorphisms (CP) is increased in infertile couples, but its impact on reproduction is uncertain, especially undergoing assisted reproductive technology treatment. The purpose of the present study was to investigate the effect of CP on the outcomes of in vitro fertilization/intracytoplasmic sperm injection-embryo transfer (IVF/ICSI-ET) treatmentMETHODS:
A total of 1331 infertile couples undergoing IVF/ICSI treatment were involved in this retrospective case-control study. The participants were divided into 4 groups according to CP variations (i) normal chromosomes (NC) group; (ii) CP group; (iii) both chromosomal polymorphisms (BCP) group; and (iv) double chromosomal polymorphisms (DCP) group. The CP group was further divided into five subgroups qh+, D/G, inv(9), Yqh+ and Yqh-. The outcomes of IVF/ICSI-ET treatment were compared among the groups.RESULTS:
There were no differences observed between the eight groups in terms of number of oocytes retrieved, MII rate, fertilization rate, cleaved embryo rate, and quality embryo rate for both females and males (p > 0.05). In both male and female, some of the CP subgroups experienced more oocyte retrieval operations and more embryo transfer operations to achieve pregnancy than the NC groups (p < 0.05). The rates of live births were significantly lower in some of the CP subgroups compared to the NC group (p < 0.05).CONCLUSION:
In conclusion, the pregnancy outcomes of ET were affected by CP. It was speculated that this may be associated with the effect of chromosome polymorphism on embryo quality, although this could not be observed or determined by morphological evaluation.Key words
