in order to fool us. I can’t believe you’re speaking truth and yet I know a lie would choke you … Well, well. Will he speak to us, as it seems he spoke to you?’
‘That’s what he seeks: to speak, to be heard. There or here. Tibe will silence him if he tries to be heard again in Karhide. I am afraid for him, he seems not to understand his danger.’
‘Will you tell us what you know?’
‘I will; but is there a reason why he can’t come here and tell you himself?’
Yegey said, biting his fingernail delicately, ‘I think not. He has requested permission to enter the Commensality. Karhide makes no objection. His request is under consideration …’
7: THE QUESTION OF SEX
From field notes of Ong Tot Oppong, Investigator, of the first Ekumenical landing party on Gethen/Winter, Cycle 93 E.Y. 1448
1448 day 81. It seems likely that they were an experiment. The thought is unpleasant. But now that there is evidence to indicate that the Terran Colony was an experiment, the planting of one Hainish Normal group on a world with its own protohominid autochthones, the possibility cannot be ignored. Human genetic manipulation was certainly practised by the Colonizers; nothing else explains the hilfs of S or the degenerate winged hominids of Rokanan; will anything else explain Gethenian sexual physiology? Accident, possibly; natural selection, hardly. Their ambisexuality has little or no adaptive value.
Why pick so harsh a world for an experiment? No answer. Tinibossol thinks the Colony was introduced during a major Interglacial. Conditions may have been fairly mild for their first 40 or 50,000 years here. By the time the ice was advancing again, the Hainish Withdrawal was complete and the Colonists were on their own, an experiment abandoned.
I theorize about the origins of Gethenian sexual physiology. What do I actually know about it? Otie Nim’s communication from the Orgoreyn region has cleared up some of my earlier misconceptions. Let me set down all I know, and after that my theories; first things first.
The sexual cycle averages 26 to 28 days (they tend to speak of it as 26 days, approximating it to the lunar cycle). For 21 or 22 days the individual is somer, sexually inactive, latent. On about the 18th day hormonal changes are initiated by the pituitary control and on the 22nd or 23rd day the individual enters kemmer, œstrus. In this first phase of kemmer (Karh. secher) he remains completely androgynous. Gender, and potency, are not attained in isolation. A Gethenian in first-phase kemmer, if kept alone or with others not in kemmer, remains incapable of coitus. Yet the sexual impulse is tremendously strong in this phase, controlling the entire personality, subjecting all other drives to its imperative. When the individual finds a partner in kemmer, hormonal secretion is further stimulated (most importantly by touch – secretion? scent?) until in one partner either a male or female hormonal dominance is established. The genitals engorge or shrink accordingly, foreplay intensifies, and the partner, triggered by the change, takes on the other sexual role (? without exception? If there are exceptions, resulting in kemmer-partners of the same sex, they are so rare as to be ignored). This second phase of kemmer (Karh. thorharmen), the mutual process of establishing sexuality and potency, apparently occurs within a time-span of two to twenty hours. If one of the partners is already in full kemmer, the phase for the newer partner is liable to be quite short; if the two are entering kemmer together, it is likely to take longer. Normal individuals have no predisposition to either sexual role in kemmer; they do not know whether they will be the male or the female, and have no choice in the matter. (Otie Nim wrote that in the Orgoreyn region the use of hormone derivatives to establish a preferred sexuality is quite common; I haven’t seen this done in rural Karhide.) Once the sex is determined it cannot change during the kemmer-period. The culminant phase of kemmer (Karh. thokemmer) lasts from two to five days, during which sexual drive and capacity are at maximum. It ends fairly abruptly, and if conception has not taken place, the individual returns to the somer phase within a few hours (note: Otie Nim thinks this ‘fourth phase’ is the equivalent of the menstrual cycle) and the cycle begins anew. If the individual was in the female role and was impregnated, hormonal activity of course continues, and for the 8.4-month gestation period and the 6- to 8-month
