Plain-English summary
Ten stray male dogs diagnosed with low sperm counts (oligozoospermia) received a treatment called platelet-rich plasma (PRP) to see if it could improve their semen quality and testicular blood flow. Half of the dogs got a single injection of PRP into each testicle, while the other half received no treatment. Over the next eight weeks, the dogs that received PRP showed significant improvements in sperm concentration, movement, and overall quality, along with better blood flow to the testicles and increased testosterone levels. This suggests that PRP could be a helpful treatment for dogs with low sperm counts.

Abstract
Platelet-rich plasma (PRP) is widely used in regenerative medicine, and the current study aimed to investigate the effects of autologous PRP on semen characteristics, testicular blood flow, and testosterone levels in the treatment of oligozoospermia in dogs. Ten stray male dogs diagnosed with oligozoospermia were included in the study. The dogs were randomly assigned to two groups: Group I, the control group (n = 5), which received no treatment, and Group II, the PRP group (n = 5), which received a single intra-testicular injection of 0.5 mL of autologous PRP into each testicle. Testicular hemodynamics, hormonal and biochemical analysis and semen parameters were assessed for both groups and the examination was extended to 8 weeks. The results demonstrated that dogs treated with PRP showed significantly higher values of End Diastolic Velocity (EDV) and Peak Systolic Velocity (PSV) (P < 0.001) at the 6to 8weeks post-injection, compared to baseline (day 0) values. Conversely, the values of Resistance Index (RI) and Pulsatility Index (PI) showed a significant decrease (P < 0.001) in group II from week 2 to week 8. Additionally, PRP treatment led to significant increases in sperm concentration, motility percentage, and the proportion of live and normal spermatozoa (P < 0.001), with maximum values observed at 28 and 60 days post-treatment, compared to day 0. Moreover, serum testosterone and nitric oxide (NO) levels were significantly higher (P < 0.001) in group II and remained elevated through the 8week following injection, compared to baseline values and group I. In conclusion, this study demonstrates that autologous PRP treatment effectively increases sperm concentration, motility, and normal spermatozoa, improves testicular blood flow, and elevates testosterone and NO levels. These findings suggest that PRP may be a promising therapeutic option for the treatment of oligozoospermia in dogs. Further studies are needed to confirm and expand upon these results.
