we feel it is of paramount importance for all patients
to fully understand their chances for success. All
too often we have found patients to be truly unaware
of their chances for success for a given procedure
performed outside of our facility. From an ethical
perspective, informed consent must include the chances
for success. Since some of these procedures are not
covered by insurance, it becomes even more important
for the patients to be aware of their probability

This data collection includes about 500 donor sperm
procedures all captured over a 10-year time span.
The data is separated with regards to female age.
In general, as one grows older, the overall success
rates diminish. The normal pregnancy rates with healthy
couples engaged in natural intercourse are used for
comparison and are 20% per cycle for those < 35
years old, 15% per cycle for the 35-39 age bracket
and only 10% per cycle (or perhaps lower) for those
40 and older.
The chart above and graph below are further divided
with respect to procedure. TDI alone refers to the
placement of donor sperm alone during a natural cycle
(blue bars). For those that do not ovulate or are
not successful with the TDI procedure alone, oral
ovulatory agents (brown-tan bars) may be added such
as clomiphene citrate (CC).

Overall, the success rates increase as the level of
intervention increases but the overall success rates
decrease as the women age.
