==Reproduction==

+

The reproductive systems are major organs of the nematodes and can occupy a large portion of the body cavity in males and females. There are many morphological and physiological differences between the species and so they are separated here.

+

====Males====

+

Males are either monorchic (most secernentea) or diorchic (most Adenophera), with regards to the number of testis present. The testis are tubular structures lined with epithelium and glandular tissue, sperm are produced at the end and mature as they migrate towards the shared opening of the cloaca.

====Females====

=== Recognition Features ===

−

*The shape of the pharynx is characteristic in some groups

−

*There is a nerve ring around the pharynx and four longitudinal nerves with ganglia that co-ordinate movement (many anthelmintics act by disrupting neuromuscular co-ordination)

*The sexes are separate:

**the female tail generally ends in a blunt point
