Title: Female Fertility Clock Closes to Tick around the Age of 43


Objective: To investigate if attempting In Vitro Fertilization (IVF) in women over 40 is of worth. 
Materials & Methods: Two hundred and thirty nine women over 40 years of age undergoing IVF were enrolled. Long protocol was used for down-regulation followed by stimulation and IVF-ET. The primary outcome measure was live-birth rate. Secondary outcomes included rates of miscarriage, cycle cancellation, obstetrical complications, and maternal and fetal adverse events. 
Results: Clinical pregnancy rates per cycle were 42.85 %, 39.34 %, 34.09 %, 27.27 % and 16.66 % for 40, 41, 42, 43 and 44 years old, respectively. Absolute difference in live birth rate in age 40 - 44 vs control, -15 percentage points; 95 % Confidence Interval (CI) -45 to 15.1, -18.77 percentage points; 95 % CI,(-56.31 to 18.79), -23.77 percentage points; 95 % CI,(-71.31 to 23.81), -25.82 percentage points; 95 % CI, (-77.48 to 25.84) and, - 27.72 percentage points; 95 % CI, (-83.16 to 27.76), respectively. Intra-uterine growth restriction and preterm delivery occurred significantly more frequently in the age group of 42 and above. Only one IVF cycle in patients aged 44 resulted in delivery.
Conclusion: It appears that IVF treatment should be limited to patients not older than 43 years, with adequate ovarian response.
