Abstract

The aims of the present study were to scan the echogenicity of reproductive organs of bucks during the breeding season. The influence of testosterone on haemodynamic Doppler indices of accessory genital glands of breeding bucks was also examined. Ten clinically healthy, sexually mature, Egyptian Baladi male goats were examined and the testes, tail of epididymis and accessory sex glands imaged using greyscale B-mode, colour Doppler ultrasonography. The spectral Doppler indices (pulsatility index and resistive index) were measured. Blood samples were collected and serum concentrations of testosterone, FSH and LH were determined. The results revealed that the echogenicity of testes, tail of epididymis and accessory genital glands was changed by breeding season. Pulsatility index values of supra-testicular artery, marginal artery, tail of the epididymis, ampulla, vesicular gland, pars disseminata of the prostate and bulbourethral gland were 0.85±0.04, 0.54±0.03, 0.4±0.03, 0.37±0.04, 0.51±0.03, 0.39±0.02 and 0.41±0.04, respectively. The resistive index of the above criteria were 0.51±0.04, 0.37±0.02, 0.3±0.03, 0.27±0.02, 0.31±0.03, 0.32±0.03 and 0.32±0.03, respectively. Serum testosterone concentration was 4.78±0.46 ng/mL. Furthermore, FSH and LH were 3.71±0.43 and 1.8±0.17 mIU/mL, respectively. Interestingly, testosterone clearly deceased the values of the both the pulsatility and resistive indices of the accessory genital glands of breeding bucks. Season modified the echogenicity of testes, epididymis and accessory genital glands. Testosterone regulated the reproductive indices of blood flow of the accessory genital glands of breeding bucks. Thus, this study could serve as a baseline of reference values of Egyptian Baladi male goats during the breeding season to improve reproductive efficiency.
