TSBC Success Rates
Every year, we calculate the overall success rate of our recipients and the rates associated with method of insemination and recipient age. We use four years' worth of data to provide better estimates of the likelihood of conceiving. The most recent analysis is for conception attempts and outcomes from 2004 through the end of 2007.
Vaginal Insemination & IUI Combined Success Rate: 14.6% per cycle
This rate of 14.6% or a 1 in 7 chance of conceiving each cycle attempt matches industry standards for conception through donor insemination. The rate is based on 4589 cycle attempts. It includes (i) all recipients regardless of their age and (ii) all insemination attempts done vaginally, intrauterine and combined vaginal and intrauterine. Based on an older life table analysis across consecutive cycles, 80% of TSBC recipients conceive within 7 cycle attempts.
We have a small group of recipients who use IVF to conceive rather than IUI or vaginal insemination. They are working with a fertility clinic as well as TSBC. This group includes women of all ages who use egg donation or their own eggs. Keeping in mind the small number of cycle attempts (n = 160) and that some women are using donor eggs, the success rate for this group matches or exceeds rates typically reported by clinics:
IVF Success Rate: 53.8% per cycle
We include this success rate to provide a comparison basis for IVF success rates which are typically published by fertility clinics. In contrast, it is less common for donor insemination programs to publish their success rates.
