Infertility treatment: relative effectiveness of conventional and assisted conception methods.
The effectiveness of infertility treatments is still questioned, particularly the assisted conception methods because of their complexity and cost. Furthermore, pregnancies often occur independent of treatment but many treatments have not been properly evaluated. The most basic audit of outcome with or without treatment requires pregnancy and preferably birth rates to be calculated in a cycle-specific and/or time-specific way; cumulative rates are the preferable method of calculation, in order to account for the usual tendency for fecundity to fall progressively. The choice of treatment usually depends on a balance of the chances of conceiving with or without treatment, and with more or less complicated treatments, and on other factors such as duration of infertility and the woman's age. This review aims to address those choices by assessing the actual and comparative effectiveness of treatments insofar as there are well defined and strictly comparable time-specific or cycle-specific published data available. Cumulative rates are described wherever possible and presented graphically for easy reference.
