The freezer is a feature on Horse Reality that allows you to store semen vials. These can be used to artificially inseminate you mares. The freezer can be found under “Personal” in the left menu of the Horse Reality website.
The Freezer lists all the semen vials you own alphabetically by the stud names. On the left of each stud's description, you can see how many vials you have of that stud. If you click on a specific stud, their image will be shown on the right of the screen, where you have the option to view the horse's profile or discard its vials.
On the top right of the screen, there is a button to discard ALL the semen vials in your Freezer, and a button that will bring you to the Veterinary. There, you can collect or use vials.
You can collect semen vials from your studs at the Veterinary every two days. Players with a Premium Account can collect semen from all studs at once.
You can also purchase semen vials on the Market. Go to the “explore” page and select “Studs & semen”. You can use the filter option to show semen vials only.
There is no limit to how many vials you can own.
Mares can be artificially inseminated with semen vials at the Veterinary. To be able to inseminate a mare, she needs to be brought in heat first by giving her a hormone injection.
