Outcome of intracytoplasmic sperm injection in patients with polycystic ovary syndrome or isolated polycystic ovaries.

OBJECTIVE

To determine the intracytoplasmic sperm injection (ICSI) and embryo transfer (ET) performance of patients with polycystic ovary syndrome (PCOS) and isolated polycystic ovarian (PCO) morphology.

DESIGN

Case-control study.

SETTING

IVF Center, Hacettepe University Faculty of Medicine.

PATIENT(S): Ninety-nine consecutive infertile women (n = 109 cycles) with PCOS and 58 patients (n = 58 cycles) with isolated PCO morphology were recruited. The control group consisted of 210 patients (n = 232 cycles) with isolated male factor infertility necessitating ICSI. All three groups were matched for female age and body mass index.

INTERVENTION(S): Controlled ovarian hyperstimulation and ICSI.

MAIN OUTCOME MEASURE(S): Oocyte number, fertilization rate, embryo quality, clinical pregnancy rate, implantation rate, and ovarian hyperstimulation syndrome (OHSS).

RESULT(S): Six (5.5%) cycles in the PCOS group, 6 (10.3%) cycles in the PCO-only group, and 10 cycles (4.3%) in the control group were canceled. Despite a significantly lower total FSH dose used, a significantly higher serum E2 level was attained in both the PCOS and the PCO-only groups compared to the control group. The PCOS and PCO-only groups had significantly higher numbers of retrieved oocyte-cumulus complexes and metaphase II oocytes compared to the control group. The fertilization rates did not differ among the three groups. The mean number of embryos transferred was comparable among the three groups; however, the mean number of grade 1 embryos was significantly higher in the PCOS and PCO-only groups compared to the controls. The clinical pregnancy rates per ET of both the PCOS (66%) and the PCO-only (60%) groups were significantly higher than that of the control group (44%). However, the implantation rates were comparable among the three groups. Four cycles (3.7%) in the PCOS group had OHSS necessitating hospitalization. The respective figures in the PCO-only and the control groups were 1 (1.7%) and 3 (1.3%).

CONCLUSION(S): Patients with the full-blown picture of PCOS or isolated PCO-only morphology behave exactly in the same manner during all stages of assisted reproduction. Owing to the availability of more fertilized oocytes and grade 1 embryos, patients with PCOS or PCO-only morphology are associated with higher clinical pregnancy rates per ET compared to patients with isolated male factor infertility.
