Abstract

BACKGROUND: Oocyte retrieval in women with low ovarian reserve is challenging and often results in poor pregnancy outcomes. AIM: The aim was to compare outcomes of oocyte retrieval using three aspiration methods in women with normal and low antral follicle counts (AFCs). STUDY DESIGN: Retrospective cohort study. SETTING: Tertiary care hospital. MATERIALS AND METHODS: Data from 172 women who underwent in‑vitro fertilization/intracytoplasmic sperm injection over 3 years was studied after dividing into three groups: Group A (96) ‑ normal AFC (≥10), direct oocyte retrieval at 120 mmHg, Group B (41) ‑ low AFC (<10), direct retrieval at 140‑mmHg, Group C (35) ‑ low AFC, follicular flushing, and aspiration at 120‑mmHg. In each group, oocyte yield, embryo quality, and pregnancy out comes were assessed. RESULTS: The oocyte and embryo yield in Groups A and B were comparable (P > 0.05) but were significantly less in Group C (P < 0.05). The pregnancy rates in Groups A and B were similar (35.4%, 39%) but were significantly less (17.1%) in Group C (P < 0.05). The live birth rate was 76% in Group A, 69% in Group B, and 50% in Group C. The miscarriage rates in the three groups were 21%, 31%, and 50%, respectively. CONCLUSION: Direct oocyte retrieval with 140‑mmHg showed significantly better oocyte yield and pregnancy outcomes compared to flushing and aspiration in women with low AFC.
