Parasitic castration is the strategy, by a parasite, of blocking reproduction by its host, completely or in part, to its own benefit. This is one of six major strategies within parasitism.
For example, Hemioniscus balani, a parasitic castrator of hermaphroditic barnacles, feeds on ovarian fluid, so that its host loses female reproductive ability but still can function as a male.[2] This is a case of direct parasitic castration (feeding on host gonads). Indirect strategies are also seen such as diverting host energy from gonad development or secreting castrating hormones.[3]
The parasitic castration strategy is used by some larval trematode parasites of snails and some isopod and barnacle parasites of crustaceans.[4] For example, 18 species of trematodes are known to parasitically castrate the California horn snail, Cerithidea californica.[5]

⭐. Degeneration of gonads ( testies) of the host due to presence of a parasite is called " parasitic castration".
⭐. Ex: sacculina causes degeneration of ovaries in the crab.
