Overexcited Stallion

Print Email Add to Favorites

I have a stallion that "saucers" (exhibits glans penis enlargement) prior to mounting. We have to back him up several times before he can mount and penetrate the mare. Any suggestions?                 Larry, via e-mail

Saucering is a description of enlargement of the glans penis (the tip) during copulation. This enlargement of the glans penis is thought to aid in dilation of the cranial vagina and cervix for deposition of semen directly into the uterus.

Enlargement of the glans penis typically occurs after the stallion has intromitted, or the penis has entered the vagina. Some stallions require less sexual stimulation than others to achieve glans penis enlargement. Occasionally stallions will achieve this prior to intromission, occasionally accompanied by emission (involuntary discharge of semen) and/or ejaculation.

With a stallion that saucers prior to intromission, efforts can be made to manage sexual excitement to allow intromission before the stallion achieves a complete erection and saucering.

This might include decreasing the duration of time the stallion teases or is exposed to the mare before copulation, washing the penis with cool water, and gently deflecting the penis downward prior to mounting and intromission when the stallion becomes overly excited. Intromission might then be assisted by attending personnel to ensure the glans inserts directly into the vagina of the mare.
