The present study investigates the effects of vascular parameters in testicular vessels on sperm quality in Pomeranian dogs with alopecia X. In the study, Doppler parameters such as peak systolic velocity (PSV, cm/s), end-diastolic velocity (EDV, cm/s), resistive index (RI), and pulsatility index (PI) of testicular arteries were measured in the healthy control group and dogs in the alopecia X group, and motility, progressive motility, and abnormal morphology analyses were performed in semen collected from dogs. When the obtained results were examined, it was determined that RI and PI parameters were higher, and the examined spermatological parameters were significantly lower, in dogs in the alopecia X group compared to the healthy control group (p < 0.05). It is thought that increased RI and PI values may negatively affect spermatogenesis by causing insufficient blood flow in the testicles and that a decrease in sperm motility, progressive motility, and morphological parameters may be related to this situation. The results obtained provide important data on the negative effects of alopecia X on reproductive health and emphasize that this disease should be addressed in male dogs not only in terms of dermatological but also reproductive functions.

Sunulan çalışma, alopecia X'li pomeranian ırkı köpeklerde testis damarlarındaki vasküler parametrelerin sperm kalitesi üzerindeki etkilerini araştırmayı amaçlamaktadır. Çalışmada sağlıklı kontrol grubu ile alopecia X grubunda bulunan köpeklerde testis arterlerinin pik sistolik hızı (PSV, cm/s), son diyastolik hız (EDV, cm/s), rezistif indeks (RI) ve pulzatilite indeksi (PI) gibi doppler parametreleri ile köpeklerden alınan spermadan motilite, progresif motilite ve anormal morfoloji analizleri yapılmıştır. Elde edilen sonuçlar incelendiğinde alopesi X grubunda bulunan köpeklerin sağlıklı kontrol grubuna kıyasla daha yüksek RI ve PI parametreleri, incelenen spermatolojik parametrelerde ise alopesi x grubunda bulunan köpeklerin sağlıklı kontrol grubuna kıyasla anlamlı derecede daha düşük olduğu belirlenmiştir (p<0,05). Artan RI ve PI değerlerinin testislerde yetersiz kan akışına yol açarak spermatogenezi olumsuz etkileyebileceği, sperma motilitesi, progresif motilite ve morfolojik parametrelerdeki düşüşün de bu durum ile ilişkili olabileceği düşünülmektedir. Elde edilen sonuçlar alopecia X'in üreme sağlığı üzerindeki olumsuz etkilerine dair önemli veriler sağlamaktadır ve bu hastalığın erkek köpeklerde yalnızca dermatolojik değil, aynı zamanda üreme fonksiyonları açısından da ele alınması gerektiğini vurgulamaktadır.
