“…The role of NO in sperm physiology is still unclear although it is well-known that it is involved in sperm motility, capacitation, and fertilization in mammals 44 , 45 . A recent study demonstrated that elevated NO metabolites were associated with sperm dysfunction in horse stallions 46 . Our results showed higher NO x levels in the azoospermic individual than in the normospermic stallions and significant negative correlations with all sperm function parameters.…”

Seminal plasma (SP) of donkey stallions was evaluated using various oxidative stress parameters as well as protease and protease inhibitor activities. SP was obtained by nine donkey stallions. In addition, one donkey stallion with non-obstructive azoospermia was enrolled in this study. Free radical scavenging activity (FRSA), the ferric reducing ability of plasma (FRAP), total antioxidant capacity (TAC), and total thiol level (TTL) were highly correlated with each other and with the protease inhibitor activity. However, only FRAP, TAC, and the nitrate/nitrite concentration (NOx) were significantly correlated with sperm concentration, production, and kinetics. Protease inhibitor activity was highly correlated with sperm concentration and production; however, it did not correlate with sperm kinetics. The azoospermic stallion produced a lower amount of semen than the normospermic stallions and its SP showed a lower antioxidant activity when evaluated with FRAP, TAC, and TTL as well as a higher NOx and a lower protease inhibitor activity. In conclusion, the evaluation of SP oxidative profile by FRAP, TAC, and NOx may provide reliable information on donkey sperm quality whereas protease inhibitor activity may play a role as a marker of the sperm concentration in this species.

The aim of this study was to elucidate histological characteristics of the vesicular glands as well as to investigate vesiculitis and its association with ampolititis and prostatitis. Sex gland samples from 40 bulls were collected. The vesicular glands were descriptively evaluated, the number of acini was counted in an area of 25mm2, compared to the number of acini between healthy and pathological glands, the data were submitted to the Student's T test at 5%. Inflammatory tissue was investigated in the ampullae of the vas deferens and in the prostates, the chi-square test at 5% was performed to assess the association between the inflamed glands. Regarding inflammation in the gland (vesiculitis), 30 animals (75%) were positive. The vesicular glands presented an average of 355 ±76.4 acini/25mm2. When comparing the amounts of acini between the glands with and without vesiculitis, no significant difference was observed, p=0.930. When performing the chi-square test to assess the association between vesiculitis and ampolititis or vesiculitis and prostatitis, the results were p=0.356 and p=0.300 respectively. Despite the high incidence of inflammatory reaction in the glands, no association was observed between the accessory sex glands studied here.

The present study compared the quality of sperm collected by artificial vagina or pharmacologically induced ejaculation from a 10-year-old thoroughbred stallion with seminal vesiculitis. The pharmacological protocol involved intravenous administration of detomidine (0.01 mg/kg) and oxytocin (20 IU) and successfully induced ejaculation in all attempts of semen collection. Sperm motility, plasma membrane and acrosome integrity (PMAI), reactive oxygen species (ROS) levels, polymorphonuclear neutrophil (PMN) percentage, and bacterial profiles of fresh and cooled semen (5°C for 24 hr) were evaluated. Semen obtained by the pharmacological method presented reduced seminal volume, decreased PMN percentage and superior sperm motility in cooled samples. Moreover, higher PMAI and lower ROS levels were observed in semen collected by the pharmacological method. Therefore, pharmacologically induced ejaculation is an alternative to obtain semen with minimal contamination and with sperm of superior quality and longevity from stallions with seminal vesiculitis.
