I felt great self-hatred at points about the fact that I was in an unknown world.

I'd never seen or met anyone like me and didn't even know anyone else existed like this," she tells me.

(2016): Darwinian sex roles confirmed across the animal kingdom. Koene JM, Pförtner T, Michiels NK (2005): Piercing the partner's skin influences sperm storage in earthworms.

Using manipulative experiments in the sea slug genus we have shown that conditional reciprocity may indeed exist, even though the costs and benefits involved remain to be studied. Current Biology 15: R792-R793, [full text] Janicke T., Häderer I.

projects finished] We are broadly interested in understanding the phylogenetic distribution of hermaphroditism across the animal kingdom, unraveling the social and environmental conditions that favor hermaphroditism over alternative forms of gender expression (such as separate sexes), and experimentally assessing the causes and consequences of sexual selection in hermaphrodite mating strategies. A subject collection from Cold Spring Harbor Perspectives in Biology.

Simultaneous hermaphroditism is a widespread form of gender expression among most invertebrate phyla and also occurs among fish. Lange (2014): Copulatory Wounding and Traumatic Insemination.

People are using 'hermaphrodite' in a derogatory way, and I simply won't have it.

Anthes (2008): Natural female mating rate maximizes hatchling size in a marine invertebrate.

One in every 2,000 babies is born intersex – and it's thought that doctors continue to operate on these newborns to 'assign' gender.

In some cases, these strategies can take extreme forms in "hit-and-run" systems that severely damage the partner (e.g. Using the opisthobranch sea slug genus as a test case, we currently reconstruct the evolution of hypodermic injection strategies and quantify the costs and benefits that such strategies involve for the sperm donor and the sperm reciever.

(ii) Differences in costs and benefits associated with matings in the male and female function may generate severe conflicts over mating roles, in particular if two hermaphroditic mates prefer to copulate in the same sex function.
