Many terragen organisms (such as lower animals, plants, and microbes) are defined as asexual and reproduce by vegetative propagation, by parthenogenesis, or by fission. Numerous alien species of all kinds reproduce asexually, as do certain xenosophonts.
Some Terragen sophonts are also defined as asexual. This may be a natural physio-psychological trait or a deliberate act of psychological, neurological, and physiological modification. Some Terragens choose to use bodysculpting and psychoware to remove all sexual attributes and feelings. These asexuals are a subdivison of the commonly recognised neut gender, and are defined as neuts (neuter sophonts) who do not have any form of sexual desire.
Note that (unlike asexuals) a small, but significant, number of neuts are capable of sexual desire, even lust, despite having no sexual organs. Such individuals are often capable of having satisfactory sex lives.
Although they do not 'lust' for one another, asexuals can and do have feelings of platonic love and many feel joy at having children. In order to have children, asexuals can adopt, or use cloning or artificial genetic blending to produce offspring. Since they have no reproductive organs they must use artificial reproduction technology or engeneration to produce their offspring.
