Abstract

The fine structure of epididymal and ejaculated spermatozoa from blue fox is analyzed by electron microscopy. The result of this investigation seems to indicate that the blue fox spermatozoon is of the same type as that of the dog. The apical body appears, however, to have a rather characteristic shape and to be more well-developed than found in sperm cells from the usual domestic animals.

The other structures studied in the different parts of the blue fox spermatozoon including the head, neck and flagellum displayed the same principal characteristics as those in the sperm cells of other domestic species.

In a few cases double development of the middle piece could be observed.

Sammendrag

Blårevspermienes Ultrastruktur blir beskrevet på grunnlag av elektronmikroskopiske undersøkelser av de forskjeilige celle-avsnitt.

De observasjoner som er gjort synes å tyde på at sædcellene fra blárev er av samme type som dem en finner hos hund. Spesielt tydelig er likheten når det gjeider utformningen av kjerne og akrosom. En struktur som i sin oppbygning synes å avvike noe fra dem en finner i spermier fra de vanlige husdyr er det såkalte apical-legeme eller perforatorium, som hos blårevspermier viser en svært karakteristisk utformning.

Når det gjelder de øvrige strukturer i hode, forbindelsesstykke og flagell er det ikke påvist prinsipielle avvik fra de forhold som er funnet i spermier fra tidligere undersøkte husdyrarter.

Abnorm utvikling av spermienes flagell i form av dobbelt midtstykke er påvist, men i likhet med andre abnormiteter er frekvensen av denne spermiedefekten svært lav i det materialet som her er undersøkt.
