Synonym(s): Deferentectomy


Introduction

  • Ferrets are seasonally induced ovulators remaining in estrus until they are mated or for as long as daylight lasts longer than 12 h. Hyperestrogenism results in anemia, which can be fatal Prolonged estrus.
  • A vasectomy is a surgical option for functional neutering of hobs, which can then be used to mate jills and bring them out of season through sterile mating.
  • The optimum time for vasectomy is the beginning of the breeding season (March to August). This is when testicular size increases and subcutaneous fat deposit decreases making it easier to visualize anatomical structures.

Uses

Advantages

Disadvantages

  • Requires surgical intervention carrying a risk of anesthesia, hemorrhage, infection, and wound breakdown.
  • Ideally requires an experienced surgeon to ensure enough of the spermatic duct is removed.
  • The mating process often carries a risk of fur loss and bites in the scruff of the female, which can be an issue in show animals.
  • In bigger groups of animals, males can exhibit aggression towards each other as they compete for the female in season.
  • The vasectomized hobs should not be used for 7 weeks after surgery to allow for spermatic semen degeneration.
  • Vasectomizing does not affect testosterone levels and males will retain their musky smell.
