The phantom should be designed to be comfort-able for the stallion and should mimic the same angle as the mare. If a jump mare is used, she should be in good standing heat and have her tail wrapped and perineal area washed. Restrain the mare to prevent injury to the stallion or personnel as-sisting. An artificial vagina is used to col-lect the semen for evaluation. To prepare the artificial vagina, fill it with water to obtain proper temperature and pressure.
Some models use a combination of water and air to get the proper pressure.
Because of stallions' individual natures, water temperature preference, pressure and lubrication will vary. Therefore, it is important to prepare the AV to the personal preference for the stallion being collected. However, water temperature should be governed by the ideal collection temperature for an individual stallion. Avoid higher temperatures to prevent irritation to the stallion's penis and sperm damage. Lubricate the AV with a sterile, non-spermicidal lubricant just before use.
