The Y organs of Sphaeroma serratum (females and non adult males) are glands of about 200 μm. Their cells show a large nucleus, and numerous mitochondria and free ribosomes. Golgi apparatus and endoplasmic reticulum are rare. At some intermolt stages cells with a different aspect appear. In the males of Sphaeroma, the degeneration of Y organs takes place after the puberty molt. It results in: (1) a reduced size of the nucleus, while the nucleoplasm becomes homogeneous, clear or (then ?) pycnotic, (2) the vacuolization of mitochondria, (3) the presence of vacuolar bodies, autophagic vacuoles and numerous clear vesicles. The cellular debris is perhaps removed by the hemocytes. The Y organs disappear entirely several weeks after the puberty molt.
