QUESTION
Spermiation is defined as?
OPTIONS
(A) Release of germ cells into the lumen of seminiferous tubules
(B) Release of germ cell into the lumen of oviduct
(C) Both (A) and (B)
(D) None of the above
ANSWER
(A) Release of germ cells into the lumen of seminiferous tubules
EXPLANATION
Spermiation is the release of differentiated spermatozoa from Sertoli cells into the lumen of the seminiferous tubules. The option referring generally to germ cells in that lumen is therefore the intended definition. The oviduct is a female reproductive structure, so release into it cannot define this testicular event. Spermiation is distinct from both spermiogenesis and ejaculation.
