AbstractAn Entlebucher Mountain Dog (57 months old, case 1), a Labrador Retriever (24 months, case 2) and an Irish Soft-Coated Wheaten Terrier (31 months old, case 3) were presented for breeding soundness evaluation to the clinic. During semen collection in all 3 dogs, the pre-secretion and the sperm-rich fraction showed normal consistency and colour, whereas the prostatic secretion (3 rd ejaculate fraction) appeared strikingly yellow. In cases 1 and 2, a severely decreased sperm motility (asthenozoospermia) and an increased amount of abnormal spermatozoa (teratozoospermia), and in case 3, a moderately decreased total sperm count (oligozoospermia) were detected. Sonographical examination revealed abnormal findings regarding the uretero-vesical junction and ectopic ureters. Therefore it is concluded that urine admixture to the 3 rd ejaculate fraction may indicate the presence of ectopic ureters and may cause impairment of semen quality and fertility. The present cases raise questions regarding urospermia concerning: 1. its incidence in dogs in general and in connection with ectopic ureters and 2. its relevance as a cause of deficient ejaculate quality and subfertility or infertility.

At present great attention is paid to studying genetic regulation of farm animal adaptations to environmental conditions. This problem is very important due to a wide expansion of highly productive cattle breeds created in Europe and North America. However, until the present no investigation of changing semen quality in bulls of imported breeds during their adaptations to environmental conditions of Western Siberia has been conducted. The aim of this study was to investigate semen quality peculiarities and the diversity of morphological sperm abnormalities in bulls of imported and local breeds kept in the environmental conditions of the southern part of Western Siberia. We determined sperm concentration, sperm count, and rate of sperm with progressive motility and percentage of morphologically normal spermatozoa. The rate of sperm abnormalities according to Blome’s classifcation was determined too. It was found that the mean values of sperm concentration, sperm motility and percentage of morphologically normal spermatozoa in the bulls investigated were similar to those in bulls kept in European countries. Inter­breed differences in these parameters were not found. However, bulls of the Red Danish, Angler, and Simmental breeds had a higher percentage of misshapen sperm head and pyriform sperm head than bulls of the Black­White breed. An inter­strain difference in sperm motility in bulls of the Black­White breed was observed. It was found that bulls of Reflection Sovereign 198998 strain had lover sperm motility than bulls of Wis Burke Ideal 1013415 strain. No inter­strain differences in sperm production, percentage of morphologically normal spermatozoa and rate of main sperm abnormalities were found. Thus, it has been found that the environmental conditions of the southern part of Western Siberia do not seriously affect the sperm production, sperm motility or percentage of morphologically normal spermatozoa in bulls. However, the increased rate of misshapen and pyriform sperm heads in the bulls of the foreign breeds points to a need to study sperm DNA fragmentation.

Abstract Cyathula prostrata (Linn.) Blume is a tropical herbal plant known for its important phytochemical contents and medicinal properties. But its impact on animal reproduction and fertility is yet to be fully established. Therefore, we tested the hypothesis that C. prostrata (Linn.) Blume will improve the semen quality characteristics of New Zealand White buck rabbit. Twenty-eight post-pubertal buck rabbits were used for the study. The animals were randomly assigned to four treatment groups (n = 7 per treatment) where they were fed either the control diet—0 g C. prostrata (Linn.) Blume or any of the three experimental diets containing the graded levels of C. prostrata (Linn.) Blume incorporated into rabbit pellets at 10, 20 or 30 g C. prostrata (Linn.) Blume per kg feed. The results showed that the semen volume and pH were not different between groups. Interestingly, sperm motility significantly decreased (P < 0.05) in a dose-dependent manner. Similarly, the sperm morphology also decreased in a dose-related fashion with 20 g (77.75 ± 1.31%) and 30 g (79.00 ± 2.20%) C. prostrata (Linn.) Blume being significantly (P < 0.05) lower compared with groups 0 g (88.50 ± 1.44%) and 10 g (87.50 ± 4.33%) C. prostrata (Linn.) Blume, respectively. In conclusion, the addition of C. prostrata (Linn.) Blume into the normal rabbit feeds had a positive effect on sperm count, but reduced sperm motility and morphology, and may be associated with spermatogenesis-related problems.

Introduction. Male infertility is known to contribute about half of all infertility cases. In Ghana, the prevalence of male infertility is higher (15.8%) than in females (11.8%). Sperm quality is associated with the likelihood of pregnancy and known to be the cause of male fertility problems 90% of the time. Exposure to certain environmental factors reduces semen quality in men. The study examined the effects of environmental and lifestyle factors on semen quality in Ghanaian men. Materials and Methods. This was a cross-sectional study involving 80 apparent healthy adult males in their reproductive age. Participants were males referred to the laboratory (Immunology Unit of the Korle-Bu Teaching Hospital) for semen analysis test and/or culture and sensitivity. Participants were made to fill out a questionnaire which entailed selected environmental factors (accidents or trauma, exposure to chemicals, radiation, and heat) and lifestyle habits (including alcohol consumption, smoking, and whether participants sat more or less than 4 hours per day). Semen samples were then collected by masturbation into sterile containers and analysed in accordance with WHO guidance for semen analysis within 60 minutes after ejaculation and collection. Results. About 69% of participants had semen pH within the normal range compared to 15% whose pH were lower than 7.2. There was a significantly high number of immotile sperm cells ( p value = 0.017) in participants who sat for more than 4 hours as compared to those that sat for less than 4 hours in a day. Active sperm motility and viability showed significant increase ( p value = 0.002 and 0.009, respectively) in participants who kept their cell phones in their side pockets. Smoking produced a twofold decrease in sperm count as smokers had a significantly lower sperm count ( 12.28 ± 10.95 × 10 6 /ml) compared to the smoke-free ( 23.85 ± 22.14 × 10 6 /ml). For exposure to STDs, no significant differences were recorded among study groups concerning semen quality. Conclusion. Sperm quality in Ghanaian men is associated with lifestyle habits. Smoking and sitting for long hours influenced sperm motility and count, respectively. Knowledge of the factors that influence sperm quality in this geographical region can contribute to informed decisions on effective management of infertility in Ghanaian men.

Four bulls of mixed breeds (Sahiwal × Zebu, Sindhi × Zebu, Jersey × Zebu and Holstein-Friesian × Zebu )were examined physically and their semen was evaluated in three seasons: I (Rainy): May - November, II (Winter): December - February, III (Summer): March- April. The semen volume, sperm motility, sperm concentration and percentage of dead sperm ranged from 4.1 to 7.6 ml, 56.6 to 76%, 1010.3 to 1290.7 × 106/ml and 18.4 to 24.7%, respectively. All these attributes varied significantly (p<0.05) between breeds and seasons. The variations of semen quality between breeds were not significant (p>0.05). It is suggested that the Holstein - Friesian × Zebu crossbred bull produces better quality semen than others. DOI: 10.3329/bvet.v25i2.4618 Bangl. vet. 2008. Vol. 25, No. 2, 51-61

Abstract The Cal Poly Bull Test has been offering valuable information for genetic improvement via a performance test of yearling beef bulls across the western United States since 1951. Growth and reproductive performance phenotypes were measured and collected over time. Therefore, the objective of this study was to determine the relationship between growth traits and semen quality traits. Performance records and semen samples of Hereford and Angus bulls were collected over a 12-year span from 2001–2013. A total of 1,982 records from Angus (n = 1692) and Hereford (n = 290) bulls were analyzed. All bulls were fall-born and weaned prior to the start of test in May. Bulls were fed for 99.83 ± 0.37 days in accordance with the guidelines of the Beef Improvement Federation where growth performance was assessed monthly during that period. After the conclusion of the test, usually in August, semen was collected from bulls and assessed for sperm motility, morphology and total sperm count. Bulls were retrospectively classified as low (0–1.4 kg), moderate (1.4–1.8 kg), or high (1.8–2.7 kg) average daily gain (ADG) bulls. The correlation among traits was evaluated using Pearson correlation, whereas a linear mixed model was used to evaluate the effect of growth on semen quality attributes. Bull age was moderately, negatively correlated (P &lt; 0.01, r2 = -0.3) with scrotal circumference. Sperm motility and morphology were moderately correlated (P &lt; 0.01, r2 = 0.35). Bull ADG was not strongly correlated (P &lt; 0.01, r2 = 0.15) with semen motility or morphology. The results indicated a significant breed effect (P &lt; 0.01) on semen motility and morphology. Angus bulls had a higher percent of progressively motile spermatozoa (P &lt; 0.01; 72.23% ± 0.73) when compared with Hereford bulls (65.88% ± 1.37). Additionally, Angus bulls had a higher percentage of morphologically normal sperm (P &lt; 0.01; 73.65% ± 0.59) when compared with Hereford bulls (66.29% ± 1.1). However, ADG as a class variable had no impact (P ≥ 0.50) on semen motility or morphology. Thus, these results indicate that higher levels of ADG during the testing period did not negatively impact semen quality attributes. More data must be collected to assess the biology behind the breed effects and validate the effect of body weight gain on semen quality attributes.

Background: This study aimed to investigate the influence of an oral antioxidative supplementation on sperm quality of in vitro fertilization (IVF) patients, as analyzed by sperm motility according to the WHO criteria and motile sperm organelle morphology examination (MSOME). Methods: Semen samples were collected from 147 patients before undergoing an IVF/intracytoplasmic morphologically-selected sperm injection (IMSI) cycle and 2 - 12 months after an antioxidative supplementation. Semen analysis was evaluated according to WHO and MSOME criteria. Spermatozoa were grouped according to the size of nuclear vacuoles within the sperm’s heads. Patients were divided into oligoasthenoteratozoospermic (OAT) and non-OAT men. Between first and second semen analysis, patients were supplemented orally with an antioxidative preparation. Results: After the antioxidative therapy we observed a significant reduction in the percentage of immotile sperm cells in the patients. Additionally, the percentage of class I spermatozoa according to MSOME criteria was significantly higher after antioxidative supplementation. In OAT patients the percentage of class I sperm was found to be increased, although not significantly. However, we observed a drastic improvement in sperm motility as well as in total sperm count in this group. Conclusion: The results demonstrated a considerable improvement in semen quality, notably in OAT patients. Considering the putative relationship between semen quality on the one hand and reactive oxygen species on the other, the observed changes in the sperm parameters indicate that a decline in semen quality, and even subtle morphological changes, might be associated with oxidative stress. Our findings suggest that an antioxidative and micronutrient supplementation has a remarkable benefit for IVF patients having restricted sperm parameters, in particular.

The aim of study was to examine the effect of the boar ejaculate collection frequency on the parameters of its quality. The research covered a three-year period, and four most common boar breeds in our area. A total of 1705 ejaculates were taken from Yorkshire boars, 1693 ejaculates from Landrace boars, 1106 ejaculates from Pietrain boars and 669 ejaculates from Duroc boars. Within each breed, groups were formed according to the frequency of ejaculate taking (once, twice, three, four, five, or six times a month). Evaluation of ejaculate quality was performed in a reprocentre laboratory, according to their quality standards. Quality parameters that have been determined were the volume of ejaculate, sperm concentration, progressive sperm motility, live sperm count, the number of doses per ejaculate and the overall assessment of ejaculate. Results of this study show that the volume and progressive motility increase with the increase of frequency in ejaculate taking, while the sperm concentration drops, except for the Pietrain boars. The best results were observed in ejaculates collected 5-6 times during the month. The highest mean volume of ejaculate was found in the Landrace boars (292.22 ml), in ejaculate taking frequency of five times per month. The highest average progressive sperm motility was 92% in the Yorkshire boars, on collection frequency of six times a month, while the highest concentration of spermatozoa was found in the Duroc boars in collection frequency of one taking per month (447.32 mil/ml). The results of this study indicate that the frequency of ejaculate taking affects the boar semen quality parameters.

Abstract Semen production data comprising of 55071 ejaculates of 144 bulls from Mehsana buffalo breed was analysed. The traits under study were semen volume, sperm concentration, initial sperm motility, post-thaw sperm motility and number of semen doses per ejaculate. The objective of the present study was to assess the effect of various factors affecting semen production traits and measure the semen production potential of Mehsana buffalo bulls. Data collected of semen production traits were analysed using linear mixed model, including a random effect of bull along with fixed effect of various non-genetic factors like farm, ejaculate number, season of birth, period of birth, season of semen collection and period of semen collection. First ejaculation had higher semen volume and sperm concentration resulted in to higher number of semen doses but semen quality was better in second ejaculation. Season of birth of the bull was affecting semen quality traits. As the period of birth advances semen volume increases whereas sperm concentration decreases which reflected in persistent production of number of semen doses per ejaculate. Monsoon and summer were favorable seasons for semen collection because of higher sperm concentration which resulted in to higher semen doses per ejaculate. Additionally, Monsoon collected semen had highest volume. Hence, monsoon followed by summer season would be the favorable season for semen collection. Period of semen collection affecting all the semen production traits under study but it did not have specific trend which means managemental and environmental changes over the period have sizable influence on the traits. Results of the study will help to plan future managemental practices and breeding strategies to improve semen production traits.

Collaborative semen collection in monkeys is a valuable tool in research, animal collection management, and conservation efforts. To obtain samples, monkeys are often restrained in open restraint chairs (ORC) with the “pole and collar” technique. While commonly used, this restraint is not tolerated by all individuals; some become anxious or aggressive towards the poles and people. In an effort to refine this procedure and improve welfare of the monkeys, we examined the use of a “closed box chair” (CBC), a clear, plexiglass box in which the monkey is trained to sit for sperm collection. The CBC does not require pole and collar, and although legs are secured, the arms and neck are not restrained. The use of CBCs has increased in recent years; however, there are few studies demonstrating its effects on scientific outcomes. We used positive reinforcement techniques to train 34 adult male rhesus macaques (Macaca mulatta) to provide semen samples using either the ORC or the CBC. While all CBC monkeys (n = 14) were reliably trained for this procedure, only 75% of ORC (n = 20) males completed the training (p = 0.04). It took significantly less time to train animals in the CBC than the ORC (201.0 vs. 412.4 min; p <0.001). In a controlled subset, males restrained with ORC (n = 7) produced a significantly lower ejaculatory volume than those collected by CBC (n = 10) (297.6 µL vs 522.1 µL respectively; p = 0.04) and had a lower concentration of sperm (186.0 × 106/mL vs 367.5 × 106/mL respectively; p = 0.017), although there were no differences with respect to sperm motility (p = 0.15). Our data suggest the closed box chair technique reduces stress on the animals while enhancing semen quality, supporting the use of the CBC as an important refinement.
