Retrospective cohort study on cumulative live birth rate of in vitro fertilization/intracytoplasmic sperm injection after multiple complete cycles in patients with diminished ovarian reserve

For female diminished ovarian reserve patients younger than 40 years old, multiple cycles in vitro fertilization / intracytoplasmic sperm injection treatments can help to achieve satisfactory success rates. As for elder patients aged 40 or above, more than 4 cycles of in vitro fertilization / intracytoplasmic sperm injection may have limited benefits.
