* 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
