| Summary: | Reports on causes of infertility and subfertility in male llamas and alpacas are lacking. The aim of the present paper is to present a review of the literature and an approach to breeding soundness examination of the male in these species. Results from a retrospective evaluation of breeding soundness evaluation of males intended for use as sires (N= 202) and those presented for complaint of infertility/subfertility (N= 71) are presented. Testicular hypoplasia, testicular degeneration and cystic condition of the testis were the most common findings in infertile males. In our practice, ejaculates obtained by postcoital aspiration or electroejaculation show a higher rate of sperm abnormalities than reported by others. A need for standardized breeding soundness examination guidelines is discussed. |
