What is another word for ridgling?
Pronunciation: [ɹˈɪd͡ʒlɪŋ] (IPA) 
Ridgling is a term used to refer to a young male horse or colt that has only one testicle descended into the scrotum, leaving the other undescended. The term can be used interchangeably with the words cryptorchid or monorchid. The condition occurs in about 1% of male horses and is considered a fault in breeding and racing circles. Other less commonly used synonyms for ridgling include undescended testicle or rig. It is important for horse owners and breeders to address the condition, as ridglings may have fertility issues and can exhibit stallion-like behavior due to the increased testosterone levels caused by the retained testicle.
