Gonadal steroid hormone models demonstrated to other sex changing kinds try basically consistent with those people for saddleback wrasses
This new connectivity between intercourse and you can distributing steroid account inside the protandrous and bidirectionally changing species was quite smaller uniform than others having protogynous types, like regarding 11KT

Gonadal steroid hormone patterns in saddleback wrasses are paralleled by differences in gonadal ultrastructure and steroid hormone synthetic capacity. Females exhibited greater gonadal E2 synthetic capacity than advanced sex changers in vitro when stimulated by salmon gonadotropin, while terminal phase males showed greater 11KT synthesis than females in vitro with advanced sex changers being intermediate . A follow up study compared terminal phase males with female-mimic initial phase males . Initial phase males are externally indistinguishable from females except for the genital papilla. This external similarity is likely important for success in ‘sneaker' mating tactics (a topic I return to in section 3). Initial phase male saddleback wrasses show both lower plasma levels and lower production of 11KT by the testes in vitro than terminal phase males. Read more
