germariumn.

Brit.

/dʒəːˈmɛːrɪəm/, U.S.

/dʒərˈmɛriəm/

Inflections: Plural germaria, germariums.

Origin: Formed within English, by derivation. Etymons: germ n., -arium suffix.

Etymology: < germ n. + -arium suffix, after ovarium n. Compare German Eierkeimstock (1854 in the passage translated in quot. 1857, probably after Eierstock ovary; compare Keim : see come n.² and the note at germ n.). Compare slightly later spermarium n.

Zoology.

In certain invertebrates: the ovary; spec. the part of the ovary that contains developing egg cells or cells giving rise to these (esp., in flatworms, as contrasted with the vitellarium). Also: the part of a testis that contains developing sperm cells.

1857 T. H. Huxley tr. C. T. E. von Siebold On Tape & Cystic Worms i. 20 I only observed one other slight step towards their further development; the sexual apparatus, viz., the testis, the germarium [Ger. Eierkeimstock], and the copulatory organs, were already faintly indicated.

1877 T. H. Huxley Man. Anat. Invertebrated Animals 178 A single or double germarium, having nearly the same structure as the ovary of Macrostomum.

1888 G. Rolleston & W. H. Jackson Forms Animal Life (ed. 2) 646 The germarium is always single, usually globular or elongate, and even folded on itself.

1925 A. D. Imms Gen. Textbk. Entomol. 145 The germarium is the region containing the primordial germ cells or spermatogonia which undergo multiplication.

1980 Science 29 Apr. 820/1 We observed that 25 ng of ecdysterone injected into unfed females [sc. mosquitos] caused secondary follicles to separate from their germariums.

1994 J. Büning Insect Ovary iii. 189 Male germaria of older adults house huge masses of long, slender, curved rods which are clearly thicker and of higher contrast than microtubules.

2006 H.-J. Marthy Devel. Biol. Res. in Space 30 The three structures, germarium, vitellarium and follicular layer, are paired in the bdelloids.
