title: Use of colour and spectral Doppler ultrasonography in stallion andrology.
abstract: Doppler ultrasonography is an important tool in the andrological evaluation in humans; however, this method is not so extensively used by equine andrologists. Spectral or pulse Doppler is a useful non-invasive method for the early diagnosis of subfertility problems in the male, especially those triggered by vascular disturbance. The identification of any disturbance in the blood flow of the testis is crucial for a correct diagnosis of various testicular and scrotal disorders but also to monitor the therapeutic outcome following treatment. The aim of this review is to provide an update on the current use of colour and spectral Doppler ultrasound in stallion andrology, and to promote the use of this technique during the soundness reproductive examination of the stallion, as this particular branch of reproductive medicine is receiving increasing interest.
