Overall, success rates for IVF/ICSI have steadily improved over the last
Success rates are influenced not only by the level of
expertise of the medical team but also by the characteristics of the patients
treated. While there are many talented doctors/individuals
in this field, there are none with supernatural powers.
Good statistics can be obtained by having more ideal patients
rather than difficult patients in the program. By encouraging ART treatments
for patients who are young, have had previous normal or ectopic pregnancies,
regular menstrual cycles, limited or no prior treatment and have normal sperm
factors, the advertised pregnancy rates can be increased. Many of these
patients may have conceived with simpler, less intensive treatment.
Every patient has her own unique set of circumstances that will
determine her prognosis for achieving a pregnancy.
A realistic expected pregnancy rate is 30 - 40 % per cycle
attempted. A patient may conceive in the 1st cycle or may require 3-4 attempts
before she attains success.
