SEXUAL DIFFERENTIATION



Aetiology

  • Occurs in Mares
  • X0 sex chromosome complement
  • Normal autosomal chromosome complement
  • Develop an ovary
  • There is only one active X chromosome, so Oocytes die.
  • The death of Oocytes is followed by loss of follicles.
  • This leads to Ovarian Dysgensis (abnormal development) and a highly regressed Streaky Ovary that does not secrete the normal ovarian steroid hormones.
  • The Ovary therefore lacks tone and has no follicular cycles.


Morphology

  • Normal external genetalia
  • Small stature
  • Flaccid Uterus
  • Small, inactive Ovaries
  • Complete absence of Ovarian activity and consequent Anoestrous
