Abstract

RESEARCH QUESTION: What are the reproductive outcomes of women aged 43 years and older undergoing IVF and intracytoplasmic sperm injection (ICSI) treatment using their own eggs.

DESIGN: Retrospective study of 833 woman aged 43 years or older undergoing their first IVF and ICSI cycle using autologous oocytes at a tertiary referral hospital between January 1995 and December 2019. Live birth rate (LBR) after 24 weeks' gestation was the primary outcome.

RESULTS: Ninety-five out of 833 (11.4%) had a positive HCG, whereas 59 (62.1% per positive HCG) had a miscarriage before 12 weeks' gestation and 36 (4.3%) live births were achieved. Analysis by age showed that the number of cumulus-oocyte complexes retrieved was significantly different between the four age groups: 43 years (5 [3-9]); 44 years (5 [2-7]); 45 years (3 [2-8)]); ≥45 years (2.5 [2-6]); P < 0.01; the number of metaphase II oocytes, however, was similar. Positive HCG rates remained low: 43 years (78/580 [13.4%]); 44 years (14/192 [7.3%]); 45 years (1/39 [2.6%]; and ≥46 years (2/22 [9.1%]); P = 0.03, as did LBR: 43 years (28 [4.8%]); 44 (7 [3.6%]); 45 years (0 [0%]); and ≥46 years (1 [4.5%]); P = 0.5. Multivariate regression analysis revealed that only number of metaphase II was significantly associated with LBR, when age was considered as a continuous (OR 1.08, 96% CI 1.004 to 1.16) or categorical variable (OR 1.08, 95% CI 1.005 to 1.16).

CONCLUSION: The chances of achieving a live birth in patients aged 43 years and older undergoing IVF/ICSI with their own gametes are low, even in cases of patients with a relatively 'normal' ovarian reserve for their age.
