Fertility of patients with polycystic ovary syndrome undergoing in vitro fertilization by age.

Objective: To evaluate outcomes of in vitro fertilization (IVF) among patients with polycystic ovary syndrome (PCOS) by age.

Methods: In a retrospective study, data were retrieved for patients with PCOS (Rotterdam 2003 criteria) and individuals with tubal factor infertility who underwent IVF at a center in Seoul, South Korea, between January 2003 and August 2012. IVF outcomes were compared by age group (A: 30-32 years; B: 33-35 years; C: 36-38 years; D: 39-41 years).

Results: The analysis included 307 women with PCOS and 364 with tubal factor infertility. There was a significant difference between women with PCOS and those with tubal infertility factor in the live birth rate in group B (41.3% vs 28.6%, P=0.038) and in group C (40.4% vs 15.1%, P=0.002). Among women with PCOS, no significant differences in number of retrieved oocytes were observed between the age groups (18.8 ± 9.6, 19.1 ± 10.0, 17.7 ± 7.5, and 17.0 ± 13.8). However, the clinical pregnancy rate was significantly lower in group D than in group C (47.2% vs 18.8%, P=0.042).

Conclusion: Fertility in patients with PCOS was maintained until age 38 years using IVF. Thereafter, the pregnancy rate decreased, although the number of oocytes retrieved by IVF remained stable.
