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
