Other studies have calculated the probability of
pregnancy among population groups who do not use
contraception. In clinical studies of this kind, the
probability of a live birth after exposure in any one
month is generally about 20%. From a practical point
of view, therefore, the expectancy of a continuing
pregnancy which will result in birth of a child after
any one exposed cycle with intercourse in the typical
young fertile couple with one-egg-ovulation is
somewhere in the range of 20-30%.
The Expectation of Success by
Various ART Procedures :
The results in terms of pregnancy rate per treatment
cycle vary considerably between clinics and the
evaluation of results is difficult because of the
heterogenecity of the patient population and the
different protocols used.
Average pregnancy rates in an -
-
IUI cycle are
a. 15-30% per patient cycle.
b. 10-15% per cycle
-
IVF / ICSI cycle a) pregnancy rate per
cycle is 30%.It is unlikely that the rate of
establishing a pregnancy from each egg by
fertilization and development in vitro followed by
embryo transfer can improve on the rate of normal
reproduction. Therefore, the theoretical maximum
success per egg in any one cycle is likely to be in
the 20-30% range. Please bear in mind, however, that
average patient statistics can be highly misleading
and we shall attempt to define for you as an
individual couple our best estimates of your
likelihood of success through IVF / ICSI.
Successful conception and child birth for any specific
couple cannot be guaranteed by any IVF program even if
the couple undergoes multiple attempts. The
probability of success depends on many factors
including patient age, the cause of infertility and
the talent and experience of the IVF team. No center
can guarantee results, but we try to minimize the
stress by offering all facilities under one roof.
