Examples

  • These spermatozoa, whose number Dr. Leuckart estimates at twenty-five millions, are preserved alive in a special gland known as the spermatheca, that is situate under the ovaries, at the entrance to the common oviduct.

    The Life of the Bee

  • But, the spermatheca is a "last in, first out" structure, thus if any further males inseminate a female, the last mate's sperm is the first in line to fertilise an egg.

  • I often confuse the 2 terms, spermatheca and spermatophore.

  • The spermatheca (also called the bursa copulatrix) is an organ that can't be exchanged, while a spermatophore is a packet of sperm that is given to a slug's (or a snail's) partner during mating and may or may not be stored in the spermatheca.

    How a glaring error of mine was corrected a year later

  • Her brain will be smaller, but she will possess enormous ovaries, and a special organ besides, the spermatheca, that will render her almost an hermaphrodite.

    The Life of the Bee

  • Others, again, believe that the queen has perfect control over the muscles that open and close the spermatheca on the vagina; and these muscles are certainly very numerous, complex, and powerful.

    The Life of the Bee

  • She retains only, in her spermatheca, the seminal liquid where millions of germs are floating, which, until her last day, will issue one by one, as the eggs pass by, and in the obscurity of her body accomplish the mysterious union of the male and female element, whence the worker-bees are born.

    The Life of the Bee

  • In the large cells this pressure would not take place, and the spermatheca would therefore not open.

    The Life of the Bee

  • It is imagined that the narrow aperture of the smaller cells, and the manner in which the form of this aperture compels the queen to bend forward, exercise a certain pressure upon the spermatheca, in consequence of which the spermatozoa spring forth and fecundate the egg as it passes.

    The Life of the Bee

  • In descending the oviduct to be deposited in the cells, they pass by the mouth of this seminal sac or spermatheca, and receive a portion of its fertilizing contents.
