Although prostate size was historically considered the hallmark feature of BPH in men, currently, there is only a weak correlation between prostate size and clinical severity. We performed a retrospective cohort study with the primary objective of assessing clinical signs, ultrasonographic findings, treatments, and outcomes in dogs diagnosed with BPH, with and without concurrent prostatitis. We reviewed medical records and obtained data on presenting signs, prostatic imaging, and prevalence of concurrent bacteriuria. Prostate size was determined by ultrasonography and compared to the calculated expected size based on patient age and weight. Treatment and outcome were described for the cases with a minimum 2 months follow-up. Median age of dogs diagnosed with BPH was 8 years. Clinical signs were present in 16/25 dogs and scored as mild to moderate (median Zambelli's Symptom Index for BPH score 12). The median prostatic volume to body mass ratio was 1.60 mm3/kg. Prostate size did not correlate with the symptom severity. Concurrent bacteriuria was confirmed in 4/25 cases via bacterial culture and/or cytology. Treatments pursued and responses were only available in a subpopulation of dogs (n = 9) and were highly variable. Studies are needed to determine if current treatment options for BPH in dogs resolve associated clinical signs in addition to reducing prostate size.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":"13 4","pages":"360-366"},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC8782267/pdf/nihms-1768784.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"39962781","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In humans andmice, fibroblast growth factor 2 (FGF2) improved semen motility. Platelet rich plasma (PRP), rich in GFs including FGF2, reduced postmating inflammatory response within the uterus; however, its effects on sperm are not known. PRP lysate (PRPL) is much purer than PRPand contains higher concentrations of GFs. Hence, the objective of the present study was to evaluate the effect of supplementing freshand cool-stored stallion sperm with either PRPL at 1, 2.5, 5, and 10% (also containing 1 IU/ml of heparin), or FGF2 at 0.1, 1, 10, and100 ng/ml. Motility parameters were evaluated using computer assisted semen analysis at 0, 0.5, 1, 1.5, 6, and 24 hours after treatment.For both PRPL and FGF2 treatments, there were no differences in total and progressive motility among groups. Concentrations of PRPL> 5% induced sperm agglutination via head-to-head attachment, starting at hour 1 and was more pronounced for 10% PRPL than 5%PRPL, suggesting a dose-dependent characteristic. Direct addition of PRPL to semen extender at doses < 5% might not substantiallyaffect sperm motility, whereas doses > 5% might affect sperm motility due to head-to-head attachments. Addition of FGF2 at theconcentrations studied may not affect sperm characteristics.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"49103333","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Breeding records were used to determine the effects of sunlight hours, prostaglandin F2α, human chorionicgonadotropin, deslorelin (a gonadotropin releasing hormone agonist), and progesterone and estradiol on double ovulation rates,and singleton and twin pregnancy rates. Breeding records of mares (n = 267) and their estrous cycles (n = 914) were analysed. Doubleovulations occurred in 10.5% (96/914) of estrous cycles. Twin pregnancies were observed in 42.7% (38/89) of mares that had doubleovulations. Overall, per estrous cycle pregnancy rate was 47.2% (405/858) and twin pregnancies was 4.4% (38/858). Double ovulationshad higher (p < 0.001) per cycle singleton pregnancy rate (69.7%; 62/89) than 1-ovulation cycles (44.6%; 343/769). Deslorelinincreased (p < 0.05; OR =1.24 95% CI) double ovulations and human chorionic gonadotropin tended (p = 0.089; OR =1.68; 95%CI) to increase double ovulations. Deslorelin use resulted in an odds ratio of 2.47 for a positive pregnancy (either singleton or twin)diagnosis compared to cycles without deslorelin use. None of the factors examined had a substantial impact on twin pregnancy rates.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"47538798","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Subjective progressive motilityand normal sperm from ejaculates (n = 12) were (mean ± SEM) 25 ± 11% and 24 ± 7%, respectively. From eachejaculate,1 sample was centrifuged through a silica colloid and refrigerated for 72 hours. An uncentrifuged sampleserved as control. Morphologically normal sperm was higher (p < 0.05) in semen centrifuged through the silicacolloid. Sperm motility in cool-stored semen was higher (p < 0.05) in silica colloid centrifuged semen compared tocontrol at 24, 48, and 72 hours postrefrigeration. Percent viable sperm and sperm with high mitochondria membranepotential were higher (p < 0.05) at 24 hours of postrefrigeration for semen centrifuged through silica colloid. Threemares were inseminated at alternate estrus, either with semen centrifuged through the silica colloid or with control.Inseminations (n = 3) with uncentrifuged semen (≥ 500 x 106 motile sperm) did not result in pregnancy. However,inseminations with fresh semen (n = 2) or 24 hours chilled semen (n = 2) obtained after centrifugation with singlelayer colloid (≥ 170 x 106 motile sperm) resulted in pregnancies. We concluded that hydrocele had apparentlycontributed to decreased semen quality and fertility in this stallion, and centrifugation of the ejaculate through a silicacolloid improved semen quality.","PeriodicalId":93421,"journal":{"name":"Clinical theriogenology","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"42980131","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
