To evaluate implantation rate as a function of age.
A total of 1621 consecutive cycles of IVF were evaluated for implantation as a function of age at The New York Hospital/Cornell Medical Center.
An overall implantation rate of 23.3% (1328/5691) was found. The implantation rate as a function of age decreased in a nonlinear fashion. Implantation remained constant until the age of 35 and then decreased in a significantly, linear fashion by 2.77% per year (P < 0.001, R2 = 0.975). A formula to predict implantation rates for a given age was developed: Implantation rate = -119.352 + (9.985 x Age - (0.164 x Age2)).
We have demonstrated that implantation rates remain constant until the age of 35 at which time a linear decrease of 2.77% per year is observed.
评估着床率与年龄的关系。
在纽约医院/康奈尔医学中心,对1621个连续的体外受精周期进行评估,以研究着床率与年龄的关系。
总体着床率为23.3%(1328/5691)。着床率与年龄的关系呈非线性下降。35岁之前着床率保持稳定,之后则以每年2.77%的显著线性速率下降(P < 0.001,R2 = 0.975)。得出了一个预测特定年龄着床率的公式:着床率 = -119.352 +(9.985×年龄 -(0.164×年龄²))。
我们已证明,35岁之前着床率保持稳定,此后每年以2.77%的线性速率下降。
