title: Analysis of 2,386 consecutive cycles of in vitro fertilization or intracytoplasmic sperm injection using autologous oocytes in women aged 40 years and above.
abstract: OBJECTIVE
  To estimate the live-birth and miscarriage rates in 1-year age increments for women aged ≥40 years undergoing in vitro fertilization or intracytoplasmic sperm injection (ICSI-IVF) with autologous oocytes.
  
  
  METHODS
  Retrospective database and chart analysis.
  
  
  METHODS
  Egyptian IVF and embryo transfer center.
  
  
  METHODS
  One thousand six hundred forty-five women aged ≥40 years undergoing 2004 fresh nondonor IVF-ICSI cycles.
  
  
  METHODS
  ICSI-IVF using ejaculate or surgically retrieved sperm.
  
  
  METHODS
  Pregnancy and live-birth rates per initiated cycle based on 1-year age increments.
  
  
  RESULTS
  The overall live-birth rate per initiated cycle was 6.7% (range: 10% to 0.5%). The pregnancy loss rate was 44.8% (range: 39.0% to 75.0%). The cutoff age was 43 years, when the pregnancy rate became statistically significantly lower. The live-birth rate per initiated cycle was statistically significantly higher for women <43 years old, 132 out of 1766 (7.4%) compared with women ≥43 years old, 7 out of 620 (1.1%). The miscarriage rate was 127 out of 295 (43.1%) compared with 15 out of 23 (65.2%) for the two age groups, respectively.
  
  
  CONCLUSIONS
  The success rate of ICSI-IVF as measured by live-birth rate per initiated cycle was statistically significantly higher for women aged <43 years as compared with women aged ≥43 years. Once women have attained age 43 years, alternative methods such as oocyte donation cycles or previously cryopreserved embryos are likely to be more effective.
