What does spermatozoan mean?
A spermatozoan is an individual sperm cell: the small, usually motile male reproductive cell that carries genetic material and can fertilize a female egg. The word belongs primarily to formal biological, medical, and reproductive-science contexts, where precision matters; in ordinary discussion, “sperm” is more usual when referring to the cell or to seminal fluid. Spermatozoa is the standard plural, and related technical terms describe features such as spermatozoan motility, head shape, and tail movement. The term is also an adjective when it modifies a noun, as in “spermatozoan count.” Its unusual construction gives it lasting interest: it combines the Greek words for “seed” and “animal,” reflecting an early description of the cell as a seed-like animalcule. Although more familiar terms can serve in less technical settings, spermatozoan remains a precise and useful term for distinguishing one male gamete from the material in which it is suspended.
A spermatozoan is a sperm cell, the motile male reproductive cell (gamete) that typically fuses with a female gamete during fertilization.

This is the technical noun for an individual sperm cell; “sperm” is more common in general contexts.
Relating to a sperm cell or to spermatozoa.
"The laboratory reported that the spermatozoan count was below the expected range."
The adjectival use is common in biological, medical, and reproductive-science terminology.
The standard biological plural is spermatozoa. The plural spermatozoans is also possible in general prose.
"The analysis revealed abnormal spermatozoa with damaged tails."
The word literally means “seed animal”: a spermatozoan is a microscopic cell that carries genetic material in a swimming package.
