USEF Considers Depo-Provera Rule Change

Depo-Provera Workshop

The United States Equestrian Federation (USEF) is considering a rule change surrounding Depo-Provera in show horses.

The federation announced a workshop regarding the hormone’s use for horses competing. The event is scheduled for March 13 from 1 pm to 5 pm EST at the Orlando Airport Marriott Lakeside Hotel in Orlando, FL. It is being live-streamed.

USEF states the purpose of the meeting is to address concerns regarding the efficacy, safety, and use of medroxyprogesterone acetate in show horses. USEF is reviewing the science and practices surrounding Depo-Provera.

Some horse show competitors may use Depro-Provera as a method of estrus suppression in mares when recommended by their veterinarian. Others may use the hormone to help minimize edgy behavior in stallions and geldings.

The following presenters have accepted an invitation by USEF to participate:

  • Dr. Stephen Schumacher, DVM, Chief Administrator, USEF Drugs and Medications Program
  • Dr. Patrick McCue, DVM, Ph.D., Director, Equine Reproduction Laboratory, Colorado State University
  • Dr. Jim Heird, Ph.D., Glenn Blodgett Equine Chair, Executive Professor, and Coordinator Equine Initiative, Texas A&M University
  • Mary Babick, President, USHJA

There are two ways to participate: join the moderated, public workshop where the panel will hear presentations from members before the panel reports to the Board. Secondly, members can send comments via email to for up to a week after the meeting.
