Spermatheca
Definition:
(n.) A small sac connected with the female reproductive organs of insects and many other invertebrates, serving to receive and retain the spermatozoa.
Example Sentences:
(1) Females of Ambystoma possess sperm storage glands, the spermathecae, as well as ventral glands and dorsal glands, both of uncertain function.
