Uterine sperm-egg transfer: a cost-effective alternative to IVF?

Direct transcervical transfer of spermatozoa and oocytes to the uterine cavity has been carried out in the past. This procedure could be a more appropriate approach than IVF for some anovulatory patients who require gonadotrophin stimulation, since the number of oocytes could be limited, thus reducing the occurrence of multiple gestations. However, most of the clinical pregnancy rates reported in the literature for gamete intrauterine transfer appear to be inferior to IVF pregnancy rates.
