It must be emphasized that lower or higher overall pregnancy rates are not the only determinant of your chance for pregnancy in any specific IVF program. Programs that take on more difficult cases, such as older women, women with fewer eggs, couples with severe sperm problems in the husband, etc., will have lower pregnancy rates than programs that mostly take on "easier" cases, even though they may be higher quality programs.
Many programs either do not accept or cancel women with low numbers of eggs in order to artificially inflate their pregnancy rate. We, however, accept the most difficult cases while maintaining excellent pregnancy rates.
A comparison of clinic success rates may not be meaningful because patient medical characteristics and treatment approaches may vary from clinic to clinic.
