Hence, the spermathecal opening of each worm is nearer to the male apertures of another worm. The penial setae of one worm penetrate into the tissues of other worms and hence the conjugants are held together.

At this phase, the sperm of one worm entered the spermathecae of the other worm. And after copulation, they separate and then start to produce egg cases including eggs, called cocoons.
