=== Cyclic Changes in the Ovaries ===
* Ovaries are smaller than those of the cow and their shape is more spherical.
* During anoestrus they measure approximately:
** 1.3 cm pole-pole
** 1.1. cm from the fixed edge to the free margin
** 0.8 cm from side to side
* Transrectal ultrasound is difficult, because the ovaries are difficult to access. Therefore, folliculogenesis is much harder to visualise than in the cow.
