Novel Design of an Intrauterine Insemination Cannula

Abstract

ABSTRACT Intrauterine insemination (IUI) is a method of assisted conception that involves transfer of fast moving sperms using an IUI cannula into the uterine cavity at the time of anticipated (or expected) ovulation, thereby increasing chance of pregnancy. Existing cannulas are designed to be easy to use, harmless to the cervix/endometrium, capable of negotiating the cervical cavity, and to avoid the reflux of inseminate fluid. Some of the factors which influence success of pregnancy are actual number of motile sperms, number of sperms with normal morphology, volume of inseminate and sterility during procedure. This paper proposes a novel ‘completely closed loop’ design for an IUI cannula that ensures complete emptying of washed sperm during insemination, leaving no dead space while ensuring sterility during procedure.
