Cypermethrin 3% (30 gram/liter) at the dose rate of 3mg/kg (0.1ml/kg) was used as pour-on. Sixteen healthy Yankasa rams with clinically normal genitalia were used. The animals were divided into groups A and B i.e. experimental and control groups. The experimental group was given Cypermethrin treatment as pour-on fortnightly for a period of twelve weeks. The control group was given distilled water at the same rate (0.1ml/kg) and route of administration for the same length of time. Rams from both the experimental and control groups were sacrificed for estimation of gonadal and epididymal sperm/spermatids reserves at the end of the twelve week studies. Epididymal and gonadal sperm reserves were estimated using a haemocytometer. Results showed that gonadal sperm reserves was not significantly different between the two groups (P>0.05). Epididymal sperm reserves showed that there was a significant difference between the cauda epididymis of the experimental and the control rams with the experimental rams showing lower cauda epididymal reserves of 149.75±13.13 x106/g while the control rams had a value of 244.56±17.09 x 106/g (P<0.05), the caput and corpus epididymis were not significantly different. It was concluded that 3% Cypermethrin at the dose rate of 3mg/kg given for a period of twelve weeks affects the epididymal sperm reserves at the cauda segment. It was therefore recommended that the use of Cypermethrin be applied with caution in rams as it may affect the fertility of Yankasa rams negatively.
