Geriatric reproductive systems in mares and stallions experience age-related decline, impacting fertility and overall reproductive health. Understanding these changes is crucial for managing aged equine reproduction.

Area of Science:

  • Veterinary Medicine
  • Reproductive Biology
  • Equine Science

Background:

  • Reproductive capacity declines with age in many species.
  • Geriatric horses exhibit significant individual variation in reproductive aging.
  • Aging affects both the mare's hypothalamopituitary-ovarian axis and reproductive tract, as well as the stallion's reproductive function.

Purpose of the Study:

  • To detail the functional alterations in the reproductive systems of aging mares and stallions.
  • To highlight the clinical manifestations and consequences of reproductive aging in horses.
  • To provide a comprehensive overview of reproductive challenges in geriatric equine patients.

Main Methods:

  • Review of existing literature on equine reproductive aging.

Related Experiment Videos

  • Analysis of clinical observations and documented effects on mare and stallion reproductive physiology.
  • Synthesis of information regarding the impact of age on fertility and pregnancy outcomes.

    • Main Results:

    • Mare aging: delayed breeding season entry, prolonged follicular phases, reduced ovulation induction response, irregular cycles, oocyte defects, increased embryonic death, and anestrus.
    • Mare reproductive tract aging: increased susceptibility to endometritis, compromised placental formation, higher risk of placentitis, altered gestation length, and uterine artery rupture.
    • Stallion aging: reduced sperm output, testicular degeneration, and potential decline in libido and mating ability.

    Conclusions:

    • Reproductive aging in mares significantly impacts fertility, pregnancy, and parturition, increasing risks to both mare and foal.
    • Aging stallions face reduced sperm production and potential decreases in libido and mating performance.
    • Managing geriatric equine reproduction requires understanding these age-related physiological changes and their clinical implications.
