Abstract: | A method was developed for collecting feline semen by electroejaculation combined with the use of a urethral catheter. The catheter facilitated handling the small volumes of semen for laboratory analysis. In 14 cats, semen volumes ranged from 0.019 to 0.284 ml (mean 0.076) and spermatozoa counts of ejaculates collected in the catheter ranged from 0.32 to 49.60 x 10(6) (mean 11.64 x 10(6)). Nine individuals were evaluated for retrograde ejaculation by quantitation of spermatozoa in pre-ejaculation and post-ejaculation urine samples. No spermatozoa were detected in pre-ejaculation samples but post-ejaculation urine samples contained from 0 to 11.88 x 10(6) (mean 4.55 x 10(6)) spermatozoa. The antegrade portion of the ejaculate contained from 6.3 to 100% (mean 59.1%) of the total number of spermatozoa ejaculated. |
