[Inability to have erections in male swine (author's transl)].
There are three degrees of impotence or diminished ability to have an erection: (a) there is no erection at all; (b) erection only occurs prior to ejaculation; (c) there is a short-lived erection at the beginning of ejaculation and occasionally also during the final stage of ejaculation. There are differences of degree in erection, ranging from the absence of erection to normal erection. When abnormalities such as those referred to under (b) and (c) are observed in young male swine, the mating pattern may be restored to normal as time goes on.
