Independently of the place for semen deposition, repeating the AI at 24-48 hrs intervals results in a significantly higher fertility: for fresh semen both the pregnancy rate and litter size present a significantly increase when multiple AI are performed (Linde-Forsberg & Forsberg, 1993), whilst for frozen semen the differences on the pregnancy rates are not significant, although litter size tended to increase with the number of inseminations (Linde-Forsberg, 2000, 2002a). An in-hospital version of the progesterone level test is available, which can give the user a rough idea when ovulation is going to occur. There are countless reasons why artificial insemination might be used. After heat, progesterone stays elevated for up to 2 months.
