Intrauterine Tuboperitoneal Insemination (IUTPI) (L. Mamas method)
IUTPI is a new insemination technique involving the usage of 10 ml of specifically prepared sperm. Clinical experience has shown that four millimetres of inseminate carrying spermatozoa were not sufficient for fallopian tube sperm perfusion.
In this case, a bigger volume of prepared sperm is used, thus increasing the intrauterine pressure during the procedure.
