Of these, 47 had at least one horned parent (group 1), 44 had a polled dam and a heterozygous polled sire (group 2) and 19 had a polled dam and a homozy- gous polled sire (group 3). Infertility was deter- mined by results in the field, or by testicular exa- mination in the field, and in doubtful cases by examination of semen, and pathological exami- nation of testes. All told, 19 males were completely infertile, 3 were fertile but showed typical clinical abnormalities, and 3 were fertile, but showed atypical clinical abnormalities. The incidence of male infertility or typical clinical abnormalities in groups 1, 2, and 3 respectively, was 0.0, 36.4, and 31.5 percent. It is concluded that male infertility in the Saanen breed is a recessive effect of the polled factor. Penetrance of the effect is incom- plete, and expressivity is variable.  aCongenital abnormalities  aEpididymis  aEpididymitis  aGenetic disorders  aGoats  aHumans  aMale genital diseases  aMales  aSaanen  aSpermatozoa  aTestes  aCaprino  aDistúrbio Genético  aGranuloma  aMelhoramento  aTestículo  aCarater mocho  aDisorders of sex development  aHermafroditism  aInfertilidade  aMale sterility1 aLAOR, M.1 aBARNEA, R.1 aWEISS, Y.1 aAYALON, N.  tThe Journal of Hereditygv. 54, n. 5, p. 237-240, Sep./Oct. 1963.
