Cytogenetic, hormonal, histological and semen quality examinations were performed in two unrelated male goats with developed udders (gynaecomastia). The bucks were neither stimulated for lactation nor milked. The progressive enlargement of the udder was observed between first and second breeding season (10-22 months). Karyotyping showed normal males. Plasma testosterone levels were within the range noted for normal bucks. Plasma concentrations of prolactin, growth hormone, FSH and LH were high, but comparable to normal bucks. Structure of the mammary glands was similar to that found in females. The quality parameters of semen of goats with gynaecomastia was comparable to that considered common for the species.

Wykorzystano dwa niespokrewnione ze sobą kozły z wykształconymi gruczołami mlekowymi (wykazujące ginekomastię), których nie stymulowano hormonalnie ani nie dojono Stopniowy rozrost wymion obu zwierząt obserwowano między pierwszym a drugim sezonem kopulacyjnym (w wieku 10-22 miesięcy), a przeprowadzone badania wykazały kariotyp typowy dla samców (60, XY). Poziom testosteronu, prolaktyny, hormonu wzrostu, FSH i LH w osoczu krwi zawarty był w granicach notowanych dla normalnych kozłów. Struktura tkanki wymienia była zbliżona do występującej w wymionach samic.Parametry jakości nasienia okazały się typowe dla gatunku. Oba kozły były płodne. Kozioł 1 był ojcem 39, a kozioł 2 - 103 koźląt.
