Six standard human genders

"Herm"

Hermaphrodite

Hermaphrodite, one of six standard hu genders, the others being male, merm, ferm, female, and neut. Herms have both male and female sexual organs, but their secondary sexual characteristics vary from individual to individual, ranging from fully male to fully female or a mixture between the two.

When occurring naturally among baselines and other hu clades (usually in prim or other non nanotech environments) this is most often caused by an unusual condition whereby both testicular and ovarian tissue develop. Chromosomes may be either XX, XY, or a mosaic of the two. More usually, as a fashion or lifestyle choice or clade or peer mark, a combination of bionano, nanomedibots, and specific hormone treatment are used to alter the gender. Hermophroditism is a common and natural condition among many terragen and xenobiotic life-forms.

Common gender definitions

The following table should only be used as a rule of thumb for
identification and use of gender, primarily for hominid, or at least
mammalian, clades.

	Can naturally bear children? (ie, has female primary sexual characteristics)	Can naturally contribute genetic material to others' borne offspring? (ie, has male primary sexual characteristics)	Has female secondary sex characteristics? (e.g., in humans, enlarged breasts and lack of facial hair. Non-hominid clades often use a different variety of features to make this differentiation: manes,tusks, antlers, colours, etc.)
herm	yes	yes	yes
herm	yes	yes	no
female	yes	no	yes
ferm	yes	no	no
merm	no	yes	yes
male	no	yes	no
neut	no	no	yes
neut	no	no	no

"Ferm"

Female pseudohermaphroditism


One of six standard hu genders, the others being male, herm, merm, female, and neut. A Ferm has male secondary sexual characteristics and female sexual organs.

When occurring naturally among baselines and other hu clades (usually in prim or other non-nanotech environments) this is female pseudohermaphroditism, most often caused by a missing enzyme, which causes over stimulation of the adrenal gland, overproduction of androgen, and alteration of the genitals. Chromosomes are XX and individuals with this condition have ovaries and are genetically female.

More usually, as a fashion or lifestyle choice or clade or peer mark, a combination of bionano, nanomedibots, and specific hormone treatment are used to alter the gender. The genitals are resculpted with symbiotic bionano or bioborgonics.


Merm

Male pseudohermaphroditism

One of six standard hu genders, the others being male, herm, ferm, female, and neut. A merm is a male individual with the secondary sexual characteristics of a female.

When occurring naturally among baselines and other hu clades (usually in prim or other non nanotech environments) this is male pseudohermophroditism, most often caused by a defective gene that prevents genetically male (XY chromosome) fetuses from absorbing androgen. The foetus develops testes, but otherwise continues to develop along female lines, although the vagina is often underdeveloped and there is no uterus.

In the current era the merm gender occurs most frequently as a fashion or lifestyle choice, or as a clade or peer mark. A combination of bionano, nanomedibots, and specific hormone treatments are used to alter the apperance and sex of the individual concerned. Nonsexual merms may feel "gender neutral" and often prefer the company of other merms, while sexual merms have a range of sexual behaviours open to them. 


Neut 

Humans with undeveloped or absent genitalia and secondary sexual attributes
 
One of six standard hu genders, the others being female, ferm, herm, merm, and male. Neuts have reduced their genitalia and secondary sexual characteristics to an undeveloped state, or removed them altogether.  

Popular among extreme religious and monastic clades, and various eccentric and situationist groups, clades, and movements, and (as a temporary or permanent choice) lifestyle among transmogrifists. Neuts who do not have any sexual feelings whatsoever are known as asexuals; however not all neuts have no sexual feelings, and some indeed have rich and fulfilling (and often ingenious) sex lives.

Neut modifications are (of course) not inheritable.
