Male nematodes may have one or two spicules which serve to open the vulva of females and facilitate the transmission of sperm, although sperm is not transferred directly by or through the spicules. [2] [3] The gubernaculum is another organ of the nematode male copulatory system which guides the spicules during copulation.

Mesorhabditis is a genus of nematodes.. Species in the genus Mesorhabditis exhibit an unusual form of parthenogenesis, in which sperm-producing males copulate with females, but the sperm do not fuse with the ovum.
Extremity of a male nematode showing the spicule, used for copulation, bar=100 μm [48] Most nematode species are dioecious, with separate male and female individuals, though some, such as Caenorhabditis elegans, are androdioecious, consisting of hermaphrodites and rare males. Both sexes possess one or two tubular gonads. In males, the sperm ...

The spermatheca (pronounced / s p ər m ə ˈ θ iː k ə / pl.: spermathecae / s p ər m ə ˈ θ iː s iː /), also called receptaculum seminis (pl.: receptacula seminis), is an organ of the female reproductive tract in insects, e.g. ants, bees, [1] some molluscs, Oligochaeta worms and certain other invertebrates and vertebrates.

The main male sex organs are the penis and the scrotum, which contains the testicles that produce semen and sperm, which, as part of sexual intercourse, fertilize an ovum in the female's body; the fertilized ovum develops into a fetus, which is later born as an infant. The corresponding system in females is the female reproductive system.
