Artificial insemination statistics can diminish for a number of reasons: the semen sample was not properly washed, the woman is too old, the dose of fertility medications was too low, etc.
When artificial insemination fails, the first thing that should be done is looking for the cause(s) behind it. If no apparent reason is found, experts recommend to go for a second cycle.
If a pregnancy is not achieved after the fourth attempt, other fertility treatments should be considered, such as in vitro fertilization (IVF), either conventional IVF or with ICSI.
