Extract of Male Angler Fish

Origin
The angler fish is probably best known for its unusual reproduction method:.

Effects
The artifact only affects females who are not pregnant. When they wear the extract, all males who smell it are attracted to her. Once finding her, they will proceed to bite/kiss her all over. Eventually, however, the male merges into the female until all that remains is his testicles, which the female can use to impregnate herself, though the exact method is unclear. The female can have several testicles all over her, and each time she impregnates herself, one of the pairs disappears.
