Interpretive guidelines to serial monitoring with Catalyst Progesterone
Get reliable, quantitative results to predict canine ovulation and estimate optimal fertility.
Ovulation and time of optimal fertility can be estimated by observing a distinct rise in progesterone concentrations, which is best identified with serial testing.

- Obtain a baseline measurement of progesterone and vaginal cytology at first signs of heat.
- Increase frequency of progesterone testing when 75% of cornified superficial cells are noted on vaginal cytology (typically 3–4 days after a bloody vulvar discharge is noted).
- Confirm a definitive and continued rise above 5.0 ng/mL to assess time of ovulation.
- Determine breeding schedule based on desired method of insemination and semen type.
Important note: The above are guidelines, and individual dogs may vary. Progesterone is best used in conjunction with other monitoring techniques, such as observation of clinical signs, vaginal cytology, vaginoscopy, ultrasound, and additional hormonal testing.
