Indications and Usage

iUPOD® is a self-assembling drug and hormone-free intrauterine device designed to modulate estrus behavior in mares. It may extend diestrus and reduce unwanted estrus behavior. This product requires due diligence - prescreening and follow up to make absolutely sure that a mare is a candidate for its use. Preexisting conditions and/or contamination of the uterus at insertion will affect the effectiveness of the devices.

Recommendations:

It is recommended that the iUPOD® is used for 5-7 months at a time during the performance season, when mares are likely to be cycling and able to produce endogenous progesterone, thus ineffective in transition mares.

Ultrasound the mare at least once - especially mares ≥ 15 years of age - during this period to confirm: a) the presence of the device (can be done routinely with an external metal detector and b) any excessive accumulation of uterine fluid. These devices are to be used by a licensed veterinarian only! 

Disclaimer: This product, for the purpose of modulating estrus behavior in mares, expires within a year. It has a 1-year warranty. This product may not meet everyone’s (Owner/Trainers/Veterinarian’s) expectations, as it does not contain any drugs that could affect the estrous cycle. Some mares respond to it, some mares do not, and some mares may show no alteration in the interval between cycles yet, there is an overall improvement for the season in their level of disposition and/or rideability.

• Only you and your veterinarian can decide if the iUPOD® is right for your mare!

Self-Assembling Intrauterine Device (Upod) Modulation of the Reproductive Cycle in Mares

Note: In a normal population of mares 8% will fail to ovulate (most likely to recur) affecting the effectiveness of iUPODs®.

It is recommended that the owner keep a meticulous record of the mare cycles/behavior. A Likert Scale for the owner’s reference is available at:
