Infertility cannot be universally treated with IVF; it requires specific analysis of each case. Before considering IVF, a pre-operative assessment is necessary to determine if the criteria for IVF are met. Infertility can be caused by male factors, female factors, or unknown reasons. Male factors can be addressed with artificial insemination or third-generation IVF. Female factors, like tubal issues, are suitable for IVF. If ovarian factors can stimulate follicle production, IVF is also possible. However, uterine factors causing infertility preclude the use of IVF.
