The Roanoke artificial vagina (AV) provides circumferential pressure and end pressure primarily on the distal penis and the glans penis, respectively, The glans penis will bell or flower within the enclosed end of the expanded part of the AV providing increased stimulation to the stallion. The Roanoke AV is relatively short and extends only about half way down the penile shaft, thus extra stimulation may need to be provided by grasping the base of the penis with a gloved hand. This is thought to simulate contractions of the vulva on the penile shaft, providing stimulation for ejaculation. This chapter discusses a step by step procedure for collecting semens from the stallion by using the AV. It also lists equipment and supplies needed for collecting the semens.
