[Diagnosis of early pregnancy by testing the progesterone level].

This research is about leveraging progesterone level measurement to ascertain conception in horses. If a mare’s progesterone level is under 2 ng/ml, 18 days post coupling, the mare did not conceive. This can supplement genital examination and assess hormonal irregularities in non-conceiving mares.

Overview of the Study

• The purpose of this research article is to establish a practical way to monitor conception in mares (female horses) by examining progesterone levels.
• The authors suggest that this method can help in identifying early pregnancy and can be an important tool in managing equine reproduction.

Progesterone Level as an Indicator

• The researchers highlight that the measurement of progesterone levels is a valid method for determining whether or not a mare has conceived.
• Progesterone is a hormone released after ovulation, indicating that the mare’s body is ready for potential pregnancy.
• If the mare’s progesterone level is below 2 ng/ml 18 days after mating, it indicates that conception did not occur.

Supplement for Genital Examination

• Progesterone level testing can work as a supportive method to genital examination in mares, providing another layer of accuracy when it comes to detection of a conception.
• Observing the progesterone levels does not replace a complete genital examination, but can be used in conjunction to give a more certain result.

Usefulness in Identifying Hormonal Irregularities

• The study points out the potential of this method to diagnose mares who have not been able to conceive due to hormonal imbalances.
• A low progesterone level may be indicative of an endocrine or hormonal imbalance which could be inhibiting the mare from successfully conceiving.
