=== Ultrasound ===
* Detection of a [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|'''follicle''']] and absence of a [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|'''corpus luteum''']] by palpation or ultrasound examination of [[Female_Reproductive_Tract_-The_Ovary_-_Anatomy_%26_Physiology|ovaries]].
* Detection of a [[The_Ovary_-_Follicles_-_Anatomy_%26_Physiology|'''follicle''']] and absence of a [[The_Ovary_-Corpus_Luteum_-_Anatomy_%26_Physiology|'''corpus luteum''']] by palpation or ultrasound examination of [[Female_Reproductive_Tract_-The_Ovary_-_Anatomy_%26_Physiology|ovaries]].
* Demonstration of follicle size, follicle wall thickening and follicle wall softening on ultrasound.
* Demonstration of follicle size, follicle wall thickening and follicle wall softening on ultrasound.
=== Vaginal and Cervical Examination ===
By visual; examination of the vagina and cervix using an illuminated speculum, it is possible to detect the preovulation period.
* In dioestrus, the cervix is small, constricted and firm.
* In dioestrus, the cervix and vagina are pale pink and mucus is scanty and sticky.
* During oestrus, there is a gradual increase in vascularity of the genital tract and relaxation of the cervix with dilation of the cervical os.
* Approaching ovulation, the cervix becomes very relaxed and its protrusion can be seen on the vaginal floor.
** Cervical folds are oedematous
* Vaginal folds glisten with clear lubricant mucus.
