In my studies, I have come to the conclusion that most physicians stick to the cities and towns, much like on earth, in villages you would find healers mostly.
It is understandable as a school for physicians is probably in bigger cities, research centers also. if the Caste of Physicians on Gor is so advanced it has to
mean they must have outstanding research facilities.
We see a physician in Turia in Nomad, this could be explained by the fact that Kamchak  was in Turia for a while, but it also tells to me, that you never know
where a physician may visit, be taken to or choose to live. Nothing is poured in cement, they are exceptions to almost everything or anything.
The Red Savages and Hunters, much like us on earth have their own Shaman or  healers, that seems to follow along the lines of our earthen heritage, much
like the wagon people have soothsayers and potion makers, much like the Mogolian or asian momads of Asia, maybe even The Alars to the European
gypsies.
There must be physicains up in Torvaldsland because of the town of Kassau which has a good population. But like the rest, I think that the villages, holdings
and homesteads may be served by healers, a healer to me being like some one that treats using herbs, common sense and good healing instincts much like
alternative medicine on Earth.
But, in the end, we must remember that the people of Gor are generally much healthier then the people of Gor, thus, physicians probably have more time for
research.

On the other hand, you will learn that in lighting, shelter, agricultural techniques, and medicine, for example, the Mortals, or Men Below the Mountains, are
relatively advanced. Tarnsman of Gor, page 31

It is apparent that  from reading the books and the quotes offered, that goreans have had the chance to advance in the field of medicine.  Moreso then on
earth. I personally think also that there would be less concern with germs as Gor is a healthier planet then Earth. The industrial revoluution hasnt happened
on Gor, and probably won't as, such, there will be less chances of plagues such as the Bazi plague. Even when there is a plague, because travel is less on
Gor, there are less chances of mass infections.  

"On the first day the Physician, a quiet man in the green garments of his Caste, examined me, thoroughly. The instruments he used, the tests he performed,
the samples he required were not unlike those of Earth. Further, certain pieces of his instrumentation were clearly far from primitive. For example, there was
a small machine with gauges and dials. In this he would place slides, containing drops of blood and urine, flecks of tissue, a strand of hair. with a stylus he
would note readings on the machine, and on a small screen at the top of the machine, I saw, vastly enlarged, what reminded me of an image witnessed
under a microscope." Captive of Gor page 92-93

At any rate, disease is now almost unknown among the Gorean cities, with the exception of the dreaded Dar-kosis disease or the Holy disease, research on
which is generally frowned upon by the Caste of Initiates, who insist the disease is a visitation of the displeasure of the Priest-Kings on its recipients. The
fact that the disease tends to strike those who have maintained the observances recommended by the Caste of Initiates, and who regularly attend their
numerous ceremonies, as well as those who do not, is seldom explained, though, when pressed, the Initiates speak of possible secret failures to maintain
the observances or the inscrutable will of the Priest-Kings. Assassin of Gor, page 29, 30

Stabilization Serums

The Player was a rather old man, extremely unusual on Gor, where the stabilization serums were developed centuries ago by the Caste of Physicians in Ko-
ro-ba and Ar, and transmitted to the Physicians of other cities at several of the Sardar Fairs. Age, on Gor, interestingly, was regarded, and still is, by the
Castes of Physicians as a disease, not an inevitable natural phenomenon. The fact that it seemed to be a universal disease did not dissuade the caste from
considering how it might be combated. Accordingly the research of centuries was turned to this end. Assassin of Gor, page 29

The Stabilization Serums, which are regarded as the right of all human beings, be they civilized or barbarian, friend or enemy, are administered in a series of
injections, and the effect is, incredibly, an eventual, gradual transformation of certain genetic structures, resulting in indefinite cell replacement without
pattern deterioration. These genetic alterations. moreover, are commonly capable of being transmitted. For example, though I received the series of
injections when first I came to Gor many years ago I had been told by Physicians that they might, in my case, have been unnecessary, for I was the child of
parents who, though of Earth, had been of Gor, and had received the serums. But different human beings respond differently to the Stabilization Serums,
and the Serums are more effective with some than with others. With some the effect lasts indefinitely, with others it wears off after but a few hundred
years, with some the effect does not occur at all, with others, tragically, the effect is not to stabilize the pattern but to hasten its degeneration. The odds,
however, are in the favor of the recipient, and there are few Goreans who, if it seems they need the serum’s, do not avail themselves of them. Assassins of
Gor, page 30

“Of course,” said Misk, “but we have allowed them to develop in many areas - in medicine, for example, where something approximating the Stabilization
Serums has been independently developed.”
“What is that?” I asked.
“You have surely not failed to notice,” said Misk, “that though you came to the Counter-Earth more than seven years ago you have undergone no significant
physical alteration in that time.”
“I have noticed,” I said, “and I wondered on this.”
“Of course,” said Misk, “their serums are not as effective as ours and sometimes do not function, and sometimes the effect wears off after only a few
hundred years.”
“This was kind of you,” I said. Priest-Kings of Gor, page 124


"'You spoke of knowing the Cabots for four hundred years,' I said.

'Yes,' said Misk, 'and your father, who is a brave and noble man, has served us upon occasion, though he dealt only, unknowingly, with Implanted Ones. He
first came to Gor more than six hundred years ago.'

'Impossible!' I cried.

'Not with the stabilisation serums,' remarked Misk. Priest-Kings of Gor, page 126

It is obvious upon reading about the stabilization serums that most goreans do not require the injection any longer as once a parent is injected, it passes
on to the child. Of course course as noted, slaves are inoculated also as they are prized property.

“She requires the Stabilization Serums,” said the physician.
The guard nodded.
“They are administered in four shots,” said the physician. He nodded to a heavy, beamed, diagonal platform in a corner of the room. The guard took me and
threw me, belly down, on the platform, fastening my wrists over my head and widely apart, in leather wrist straps. He similarly secured my ankles. the
physician was busying himself with fluids and a syringe before a shelf in another part of the room, laden with vials.
I screamed. The shot was painful. It was entered in the small of my back, over the left hip.
They left me secured to the table for several minutes and then the physician returned to check the shot. There had been, apparently, no unusual reaction.
Captive of Gor, page 93

“In the first house of my slavery,” I said, “I was given a series of injections. I am curious about them. Were they inoculations against diseases?”
“I know those you mean,” he said. “No, they were the stabilization serums. We give them even to slaves.”
“What are they?” I asked.
“You do not know?” he asked.
“No,” I said.
“They are a discovery of the caste of physicians,” he said. “They work their effects on the body.”
“What is their purpose?” I asked.
“Is there anything in particular which strikes you generally, statically, about the population of Gor?” he asked.
“Their vitality, their health, their youth,” I said.
“Those are consequences of the stabilization serums,” he said.
“I do not understand,” I said.
“You will retain your youth and beauty, curvaceous slave,” he said. “That is the will of masters.”
“I do not understand,” I said, frightened.
“Ageing,” he said, “is a physical process, like any other. It is, accordingly, accessible to physical influences. To be sure, it is a subtle and complex process. It
took a thousand years to develop the stabilization serums. Our physicians regarded ageing as a disease, the drying, withering disease, and so attacked it
as a disease. They did not regard it as, say, a curse, or a punishment, or something inalterable or inexplicable, say, as some sort of problem, susceptible to
physical approaches. Some five hundred years ago, they developed the first stabilization serums.”
“How could I ever pay for such a thing!” I gasped.
“There is no question of payment,” he said. “They are given to you as an animal, a slave.” Dancer of Gor, page 472


I had spent eight days in the slave pens, waiting the night of the sale. I had been examined medically, in detail, and had had administered to me, while I lay
bound, helplessly, a series of painful shots, the purpose of which I did not understand. They were called the stabilization serums. We were also kept under
harsh discipline, close confinement and given slave training.
I well recalled the lesson which was constantly enforced upon us: "The master is all. Please him fully."
"What is the meaning of the stabilization serums?" I had asked Sucha.
She had kissed me. "They will keep you much as you are," she said, "young and beautiful."
I had looked at her, startled.
"The masters, and the free, of course, if there is need of it, you must understand, are also afforded serums of stabilization," she said adding, smiling,
"though they are administered to them I suppose, with somewhat more respect than they are to a slave."
"If there is need of it?" I asked.
"Yes " she said.
"Do some not require the serum'?" I asked.
"Some, said Sucha, "but these individuals are rare, and are the offspring of individuals who have had the serums."
"Why is this?" I asked.
"I do not know," said Sucha. "Men differ."
The matter, I supposed, was a function of genetic subtleties, and the nature of different gametes. The serums of stabilization effected, it seemed, the
genetic codes, perhaps altering or neutralizing certain messages of deterioration, providing, I supposed, processes in which an exchange of materials could
take place while tissue and cell patterns remained relatively constant. Ageing was a physical process and, as such, was susceptible to alteration by physical
means. All physical processes are theoretically, reversible. Entropy itself is presumably a moment in a cosmic rhythm. The physicians of Gor, it seemed, had
addressed themselves to the conquest of what had hitherto been a universal disease called on Gor the drying and withering disease, called on Earth,
ageing. Generations, of intensive research and experimentation had taken place. At last a few physicians drawing upon the accumulated data of hundreds
of investigators, had achieved the breakthrough, devising the first primitive stabilization serums, later to be developed and exquisitely refined.
I had stood in the cage, startled, trembling. "Why are serums of such value given to slaves?" I asked.
"Are they of such value?" she asked "Yes," she said, 'I suppose so." She took them for granted, much as the humans of Earth might take for granted routine
inoculations. She was unfamiliar with ageing. The alternative to the serums was not truly clear to her. "Why should slaves not be given the serums?" she
asked. "Do the masters not want their slaves healthy and better able to serve them?" Slave Girl of Gor, page 282
