“…Ecotext can be used to identify changes in the testicular echotexture of stallions with testicular dysfunction, with lower values for Ecotext 1, Ecotext tubular area and Ecotext tubular density found in these stallions than in control stallions. Moreover, we found differences in Echotexture among stallions with acquired chronic TD and immunized stallions (da Silva‐Álvarez et al, 2022).…”

“…In a preliminary study of our lab, we have evaluated for the first time the use of power Doppler ultrasound (PD) in combination with computerized image analysis as a marker of endometritis in mares and jennies (da Silva‐Álvarez et al, 2022). Both species showed an increase in endometrial BFA in pathological uterine conditions compared to controls.…”

“…Recently, our group has evaluated a new specially developed software (Ecotext, Humeco, Spain) for testicular echotexture analysis as a diagnostic method of testicular dysfunction in stallions (da Silva‐Álvarez et al, 2022). Ecotext provides the user with a total of six different parameters (Ecotext 1 (black pixels), Ecotext 2 (white pixels) and Ecotext 3 (grey pixels), Ecotext tubular density (density of hypoechogenic areas), Ecotext tubular diameter (mean diameter of hypoechogenic areas) and Ecotext tubular area (total percentage of hypoechogenic area), that were used as functionality markers (Figure 6).…”

“…Initially, this software has been used for research purposes, because the post‐acquisition image processing does not allow real‐time decisions to be taken. However, they are now being developed for clinical purposes, as is the case with Ecotext (Humeco, Huesca, Spain), a computer program developed for the evaluation of testicular echotexture in various species, providing information on testicular functionality (Abecia et al, 2020; da Silva‐Álvarez et al, 2022).…”

Ultrasound technology has led to new lines of research in equine reproduction, and it has helped to greatly improve clinical diagnosis and reproductive outcomes in equine practice. This review aims to discuss the potential clinical uses and new approaches of ultrasonography in equine reproduction. Doppler modalities are usually used to evaluate the vascularization of the follicles, corpus luteum (CL), and the uterus in the mare for diagnostic purposes. Inclusion of Doppler ultrasound in artificial insemination and embryo transfer programs could improve the reproductive outcome of these techniques. Better selection of recipients based on CL functionality, early pregnancy diagnosis 7-8 days postovulation of the donor before flushing or diagnosis of mares with endometritis with pathological increases of blood flow are examples of clinical applications in the mare. In the stallion, colour Doppler ultrasound has improved the diagnostic potential of B-mode ultrasound, improving the differential diagnosis of pathologies such as testicular torsion (decrease or absence of blood flow in the cord) and orchitis (increased blood flow in the cord). The incorporation of pulsed Doppler ultrasound into the reproductive evaluation of the stallion has enabled early identification of stallions with testicular dysfunction, thus allowing administration of timely treatment and subsequent improvements of the fertility prognosis for these animals.In addition, this technique has been used in the monitoring of patients undergoing medical and surgical treatments, thus verifying their efficacy. Recently, computerassisted pixel analysis using specific software has been performed in research work in order to semi-quantitatively evaluate the vascularization (colour and power Doppler) and echotexture of different organs. These softwares are now being developed for clinical purposes, as is the case with Ecotext, a computer program developed for the evaluation of testicular echotexture, providing information on testicular functionality.

“…Conventional gray-scale ultrasonography (B-mode) has been routinely used for testicular parenchyma evaluation, due to the fact that echogenicity is related to the histomorphology of the seminiferous tubules but lacks information about the organ vasculature [ 12 ]. Non-invasive imaging technologies, such as color and pulse-wave Doppler ultrasonography, can be used as alternative diagnostic techniques for evaluating structural and functional hemodynamics (the fluctuation of testicular microcirculatory blood flow) in order to determine the testicular function, and, therefore, male fertility [ 13 ].…”

The goal of this study was to investigate the age-related differences in testosterone concentration and its relation to testicular biometrics, testicular blood flow, and fertility in alpacas (Vicugna pacos). Fifteen alpaca males with different ages (young (YM; ~12–14 mo.), n = 5; intermediate (IM; ~24 mo.), n = 5; and old (OM; ≥36 mo.), n = 5) were enrolled in the study. Blood samples were taken from each alpaca male and the circulating plasmatic testosterone concentration (TC; ng/mL) was determined using ELISA analysis. The testicular traits related to bio-morphometric parameters (the length (L), width (W), area (A), and volume (TV)) were assessed using B-mode ultrasonography. Pulse-wave/power Doppler ultrasonography was used to obtain the circulatory dynamic values (testicular hemodynamics) before the beginning of natural service mating. Significant differences were observed in TC among the age groups, increasing as the age of the males increased (2.47 ± 0.31, 8.45 ± 1.53, and 22.66 ± 2.15 for YM, IM, and OM, respectively; p < 0.05); however, no differences were observed regarding the testicular B-mode ultrasonographic parameters (L, W, and A) (p > 0.05). Positive correlations were observed between TV and testicular L, W, and A (r = 0.96, r = 0.95, and r = 0.96, respectively; p ≤ 0.001). Pulse-wave-Doppler-derived parameters such as the pulsatility index (PI) and the resistive index (RI), as well as the total vascularity area (TVA) assessed by power Doppler, were similar in all of the age groups studied (p > 0.05). General linear model (GLM) analysis showed a relationship between TC and TV (OR = 0.95; p = 0.04), as well as between TC and TVA (OR = 0.99; p= 0.02). Finally, no differences were observed regarding the pregnancy rate among the different age groups (p > 0.05). In conclusion, TC increased as the age of the alpaca males increased. Although TC was related to TV and TVA, the pregnancy rates obtained from individuals belonging to the different age groups were similar, indicating that TC, TV, and TVA were not determining factors in assessing the potential age-related fertility differences in alpaca males.
