An excerpt from "The Physiology of Shemales" by Dr. Felicia Carlyle 

It is simply a fact that the physiology of natural born shemales is vastly superior to most males and females. It is as if they are genetically molded to be stronger, smarter, and healthier in every way. Their excessive sperm production and heightened libido's suggest that they are simply genetically disposed to breeding as often as possible. It has even proven in recent years that a single sperm cell from the testicles of an average shemale has an 80% chance of fertilizing an egg. With billions of those cells being released with every orgasm, each with those astronomically high chances, the average shemale is almost guaranteed to impregnate her partner during ovulation. In evolutionary biology, fitness is defined as an organism's ability to find a mate, produce viable offspring, and pass on their DNA. The more offspring an organism produces, the greater its fitness. With that in mind, it is safe to say that shemales are the fittest humans despite being the fewest in number. While we currently have three distinct sexes, there is a chance that in the very distant future, we will return to a dual sex culture consisting of shemales and females only. 

When discussing the superiority of shemales and the future of the human race, I feel that it is always important to bring up the very unique case that inspired me to write this book of shemale physiology. You may have heard of Sarina Maxwell, to whom this book is dedicated too. She is the famous criminal king pin of New York City, although she will sometimes set up shop in other major cities since her empire runs far and wide across the world. Through strength, confidence, intimidation, and clever planning, Sarina has become a powerful individual and a force to be reckoned with. However, as her private physician, I am mainly interested in her physiology. I have been her doctor for 5 years now and have run extensive tests and experiments to fully understand everything about her biology. What I have learned so far is this: Sarina Maxwell is Perfect, by every interpretation of the word. 

For one, her immune system is stronger than any other ever observed or recorded. She has no record of receiving any vaccines, yet she has never had Influenza, Measles, or Varicella. She has never had an STD despite constantly being in sexual contact with individuals who can only be described as disease cocktails. She has no allergies, nor does she suffer the side effects of any drug she takes, recreational or otherwise. I have prescribed very powerful drugs whenever she has a bad hangover after a long night of her usual debaucherous behavior, the side effects to which is temporary erectile dysfunction. However, I will watch as she takes double the recommended dose before spending the next three hours in my office, with me bent over my desk as she relieves her insatiable lust. It is important to note that most shemales do not have this level of immunity. Although they are more resistant to viruses and infection, they are not completely immune. Sarina's complete immunity to disease and infection is enough to show that she is likely to live longer than just about anyone else. 

I have not provided a picture of Sarina, but she has posed nude for many magazines so a quick google search should provide you with a reference to the physique that I believe is unlike anything I have ever seen. While there are probably shemales and even some males out there who have developed their bodies much further than Sarina, her amazonian form is due more to her genetics than her commitment to exercise. Shemales have a balance of testosterone and estrogen, both produced by their testicles. While the amount of testosterone increases during exercise, it does not stay elevated outside of the gym and so it takes much more effort to both increase muscle mass and maintain it. Sarina is unusual in that while her testosterone levels increase during exercise, they are incredible high to begin with. Much more than the average shemale. This is particularly due to the size of her testicles which I will cover later in this chapter, but the hormone also remains in the synapses of her muscle fibers for much longer. For these reasons, Sarina has managed to become incredibly muscular and can maintain her incredibly strong physique, with very little effort. Of course, she keeps her weight training to two hours a day so as to maintain her feminine features. By limiting her exercise, the estrogen in her system was able to do its work without any kind of inhibitory competition, thus allowing her breasts to grow large while remaining soft. 

Sarina's genitalia are biological marvels if there ever was one. Each of her testicles are about the size of a softball and sometimes swell up to a much larger size when she is pent up. While the testicles of the average shemale will produce about 2-3 billion sperm cells each day and about a pint of seminal fluid, Sarina's testicles don't produce a set amount each day. Instead, her testes self-regulate production of semen and sperm via negative feedback. After a week without release (something she made me dearly regret), I found that 8 billion sperm cells and a whole liter of seminal fluid is the most her gonads will produce. They reach this amount in about 3 days. However, whenever Sarina ejaculates, she always ejaculates the entire contents of her scrotum. When her testes begin production again, an excess of testosterone is released causing them to produce semen at a much more rapid rate than the baseline rate of production. This is due to a backup of secondary messengers that were not degraded during the sexual hiatus. This explains her ability to ejaculate five full loads in a row after the week of no release without needing time to recover. After looking into it further, I learned that this is something that all shemales are technically capable of, but because they're orgasms aren't as intense and powerful, they do not exhaust all of their semen in one orgasm. In addition, their maximum production is less than Sarina's, meaning a negative feedback loop turns off production earlier than in Sarina's testes. 

The chemical composition of Sarina's semen is as intriguing as how it is made. I found that the seminal fluid in her semen contains all the essential vitamins and macro molecules necessary for human sustenance and growth. Simply put, a person can live entirely off her semen for the rest of their life and be completely healthy. I had my nurse assistants consume nothing, but Sarina's semen - breakfast, lunch, and dinner- for an entire month. It turned out that all-semen diet was healthier than their usual diet. I predict that the reason for this nutrient rich semen is so as to provide mothers carrying Sarina's offspring with all the nutrients necessary to produce a healthy, strong, child. However, there are some interesting side-effects of drinking Sarina's semen frequently. For one, the seminal fluid has a very high caloric density and contains quite a bit of fat. Those who drink nothing but her semen gain weight rapidly, usually in the rear, thighs, and breasts, but sometimes in the belly region as well. Luckily, it is low on cholesterol, but my nurses went from weighing 120lbs to 180lbs in a month. I'll need to do further research to make sure such fattening semen doesn't lead to heart disease or diabetes. The other unfortunate side-effect of Sarina's semen is its addictive properties. Often times, a single dose of her semen will develop into a full blown addiction. I don't mean that women are addicted to the taste as the semen tastes quite awful and even makes women wretch upon tasting it. Despite it's terrible taste, after drinking a single spoonful, by test subjects begged for more. I have discovered that one full orgasm's worth of semen is enough to create a full-blown addiction even stronger than heroine. Withdrawal symptoms after only one dose are intense, usually involving severe fever, nausea, seizures, major depression, and even brain damage. The worst case of withdrawal I have witness so far was in my nurses who had lived off a Sarina's addictive semen for a month. At the time of running the experiment, I was not aware of its addictive affects. After the month was up and they returned to their normal diets, my girls were hospitalized within 24 hours of getting off Sarina's semen. They're brains were deteriorating rapidly along with the rest of their bodies. They have since moved in with Sarina and I have gotten new nursing assistants who I constantly warn to never drink her semen. Unfortunately, they rarely listen. I strongly doubt that Ms. Maxwell takes in every woman addicted to her semen so I am sure there are dozens - maybe even hundreds of women out there who are utterly broken and untreatable. 

I was having trouble finding the chemical property of the seminal fluid that made Sarina's semen so addictive. The secret was in her sweat. The addictive chemical is actually produced in her sweat glands in high concentrations. Her sweat is laced with chemical which is why many women are drawn to her, particularly after an intense workout. Animal experts might think of this chemical as very powerful pheromones. I have found that licking or drinking her sweat will create a powerful, but significantly less intense addiction. However, unlike the semen, her sweat will induce a powerful high similar to meth. I have also found that women who snort her sweat experience a more intense high than those who simply lick it. This is probably due to the drug-like chemicals reaching the brain much faster. Now, there is a sweat gland near the groin that produces sweat in that area. With Sarina, this gland is also injecting this chemical right into her testicles. I imagine it is what gives the semen its wretched taste as well as its addictive properties. Since the chemical is more concentrated when released into her testicles, it produces a more powerful addiction. Furthermore, I believe that the sweat gland near the groin and arm pits produce more sweat than other parts of the body because 'consumption' of sweat from those areas lead women to get extremely high and possibly even overdose. One test subject that snorted the sweat off of Sarina's balls immediately after a workout had a grand mal seizure almost immediately. She was found to have suffered minor brain damage, but still wanted more. 

Sarina's penis is generally what she is known for, but I will admit that as a doctor that works exclusively with shemales, I have seen longer and thicker. Not many mind you. In fact, research shows that Sarina is in the 99th percentile for penis length and girth. However, what is most interesting about her penis is the features of the organ tissue. In males and most shemales, the three spongy tissue layers are exactly as they sound: spongy. Without blood to fill the tissue chambers, they are flexible, soft, and light in weight. However, the tissue in Sarina's penis is less spongy in nature and more closely resemble muscle fibers. They still behave the same way, but the tissue layers are thicker and need much more blood to become fully engorged. This need is met by the diameter of the internal pudic artery - the main artery that brings blood to the penis - which is double the size of the artery in other shemales. Since the tissue in her penis is much bigger, the artery does not decrease in diameter when it branches off to spread across the three columns of tissue. This is why you will see 3 very large blood vessels bulging out both when she is flaccid and fully erect. It is important to note that because of the thickness of the penile tissue and the amount of blood coursing through her penis even when it isn't erect, Sarina's flaccid cock weighs 20 pounds (9 kilograms). Even shemales with more inches to their length don't have that kind of weight. 

Having fully described Sarina Maxwell's superior shemale physiology, I hope that I have convinced you why I believe that she is perfect and probably the closest thing I've seen to an advanced species of homo sapien sapien. But if you are still skeptical, allow me to present the results of an extensive experiment I conducted to research shemale reproductive ability. 

On May 15th, 2013, I invited a dozen shemales into my home as the first part of my experiment. These subjects were the most ideal mating partners I could find. They had large genitals, above average semen production, and impressive sexual endurance. They were in peak physical condition, muscular, with a prime balance of sexual hormones. I found them all to be very attractive and so did 24 women I asked to help me in this experiment. I picked these women because they were all in their late 20's (the optimal age for conception) and 12 of them were ovulating on that day while the other 12 had just finished menstruation and were at least two weeks from their next period of ovulation. These women were interested in having children by sperm donor or simply sought enjoyable sex. On that day, I asked the shemale subjects to have an orgy with the ovulating group of women for at least 12 hours. I asked that they inseminate each woman as often as they could. The following day, on May 16th, I brought in the non-ovulating group and asked the shemale subjects to once again have an orgy with the women and to inseminate each one as often as they could. 

The results of the experiment were as I expected for the most part. Each of the women who were ovulating had become pregnant from the experiment according to pregnancy tests taken 5 days later when they were supposed to menstruating. Three of the women were pregnant with fraternal twins. In the second group of women, there were three women who had been impregnated during the experiment. Looking into further, I discovered that the shemales that had sired the fraternal twins were the same ones that had impregnated the women that weren't ovulating. 

On July 8th, I preformed the same experiment with Sarina Maxwell. This time, my two young nurses helped me conduct it. Jennifer, who had just turned 29, wanted very much to have Sarina's baby, but I usually kept her out of my office when Sarina was around, for obvious reasons. She was ovulating on that day. Courtney, 28, was two weeks from her next ovulation. Just like before, I asked Sarina to inseminate the girls, but I simply let her have intercourse with both girls at the same time. She was even kind of enough to inseminate each of them the same amount of times so as to avoid any kind of deviation or possibility of quantity being a variable. The results of this trial were baffling and enough to convince me that Sarina was in fact a superior shemale. 

Jennifer was pregnant, not with just one baby, but with 14! This made no sense at all. It didn't seem possible, but 9 months later, she gave birth to 14 children. What was even more shocking was that not only was Courtney pregnant, 9 months later, she gave birth to twelve children! At first, I thought Sarina's sperm was the key. I've always known her to have super sperm since she never failed to impregnate women when she would ejaculate inside them. Even common contraceptives failed to stop her sperm from finding their mark. But if her sperm were somehow fertilizing eggs in the ovaries, the result would be a miscarriage. But Jennifer and Courtney's pregnancies went all the way to term and their babies were very healthy. So it had to be something else. I had a hypothesis, but I needed to run one more experiment just to be sure. 

On August 25th, 2014, I asked Sarina to come in again for another experiment. Jennifer and Courtney were very eager to help me again for some reason, so I let them. But I needed to be sure there were no flukes so I asked two other women to help out. I also took part in the experiment this time. Jennifer and Courtney were both two weeks from ovulation this time. It seemed that getting pregnant at the same time, by the same sexual partner, and going through their pregnancy together, synced up their cycles. The other two women were ovulating on that day. I was a special case in that I had only one working ovary, my womb was an ill environment for a developing fetus, and as I was nearing 50, my ability to reproduce was all but extinguished. The experiment took about 18 hours because we had sex with Sarina one at a time instead of all together. In a few of the cases however, I asked Sarina to stop having sex before reaching climax. She wasn't too happy about that stipulation, but we promised to make it up to her once I had the results. Sarina accidentally released some pre-ejaculate inside Jennifer, which I found to contain no trace of sperm cells. She ejaculated on Courtney's face and I made sure none of it got into her vagina. The other two women only took part in anal sex and oral sex. There was no vaginal penetration in any form during their trial. Immediately after each woman had finished their session with Sarina, I preformed a transvaginal ultrasound. 

The results proved my hypothesis completely. What I found is groundbreaking in the field of genetic, reproductive, medical, and evolutionary biology! The ultrasound showed that Jennifer's ovaries had released 11 eggs during intercourse with Sarina! Courtney's ovaries released 8. Both of the other women, who hadn't even had vaginal sex with Sarina were each found to have 10 eggs waiting to be fertilized. The results were as clear as day. Sex with Sarina Maxwell induced the ovulation of multiple eggs. This is why she was able to impregnate my nurses with a litter of children instead of just one or two like the other shemales. Even though they were ovulating normally, more eggs were released in response to intercourse with Sarina! Some of my peers thought that there was something special about the women, particularly Jennifer and Courtney. So in response, I conducted several more experiments with other shemales. The results were never duplicated. When I conducted follow up experiments with Sarina using a multitude of variables such a women of different ages, racial groups, socioeconomic groups, women with different dietary restrictions, and even women with disabilities, the results were always the same. Women either became pregnant with entire litters, or ovulated in bulk. This brings us to the results of my trial with her. 

My trial with Sarina was the longest, going for a full 8 hours before we both fell asleep. She had released her ejaculate inside me only once as per my request. I had previously tried to conceive with a number of different shemale partners and even attempted artificial insemination a number of times. In past encounters with Sarina, I asked that she always ejaculate outside my vagina purely for the sake of professionalism. This one time I asked her to do inseminate me, I found myself pregnant with 10 babies, all of which were born extremely healthy. 

Experimental Conclusion and Further Research 

On every X chromosome, there is a small sequence of DNA previously believed to be junk DNA with no important function. We know now, this sequence codes for the newly termed Xsem69 gene. This gene regulates the production of a protein that induced ovulation regardless of other factors. The Y and Z chromosomes in males and shemales respectively, have genes that inhibit the activation of the Xsem69 gene, but in women, the gene can be activated in a very precise situation. This gene is only activated in the presence of a 'True Alpha,' the member of a species that is most superior in a population, due to physical appearance, exocrine pheromone release, and the act of domination of the female of the species. It is not known exactly what features are necessary for a female's body to recognize a True Alpha, but experimentation has shown consistently that the gene is activated in the presence of Sarina Maxwell. The reason we have not seen this phenomenon before is simply because we have not had True Alpha's in the population before. Whether Sarina Maxwell is the first remains to be seen, but she definitely is a True Alpha. Superior to the other shemales, genetically and in terms of evolution. 

We are without a doubt seeing the beginning of a new human race. Sarina is a prime example of evolution molding us into a more perfect species. Even shemales, as inferior to the True Alpha as they maybe, are the intermediates for the next step in human evolution. I doubt I will be alive to witness this miracle, but I only hope that my children and the children of all the women that took part in my experiments that were sired by Sarina Maxwell, go on to prove me right and build a new ideal world for the species that will be known as Home Sapien Gallus. 

The Alpha-Bimbo 

I would not normally use such crude terminology to describe subjects no matter how promiscuous or unintelligent they might be. However, to describe this particular individual as an Alpha-Female would be incorrect as confidence, individuality, and strength of mind are not accurate descriptions of her. The 'Alpha-Bimbo' is a woman - usually in her 20's - that is the most optimal mate for a True Alpha Shemale. Unlike a Alpha-Shemale, Alpha-Bimbo's cannot be identified so easily. While they do have unique genes that make them different than other females, those genetic and biological traits are only exhibited when they come into contact with an Alpha-Shemale. However, once this initial interaction occurs, there are some very interesting changes in biology of the female and the behavior of both the Alpha-Shemale and the Alpha-Bimbo. I observed these changes in only one instance involving Sarina and a girl who I was surprised to hear was Sarina's girlfriend. I was surprised because with the sheer number of women Sarina has slept with, I didn't think a 'relationship' was really her thing. However, I quickly learned that even their non-traditional relationship had much to do with this Alpha-Shemale/Alpha-Bimbo partnership. 

Sarina's girlfriend is named Candy. She used to be named Anna Davinski, but legally changed her name to 'Candy' after dropping out of high school to become a stripper. She worked as a stripper for 4 years (starting when she was 18), until she met Sarina. All the tests I ran on Candy took place a year after they met so I could not document the actual process of change or whether Candy exhibited these particular traits prior to their meeting. All I can do is compare her biology to that of other women. 

When women are intimate with Alpha-Shemale's like Sarina, they ovulate in bulk and release around a dozen eggs in anticipation of fertilization. Candy ovulated as well, but her ovaries released only one egg. I was very shocked by this find as it initially seemed to contradict a lot of my past research into Alpha-Shemale breeding. However, after observing a single egg cell extracted from Candy's uterus, I learned a few interesting things that might explain why she wasn't like all the other girls that Sarina mated with. The egg cell is noticeably larger than a normal oocyte. In addition, the cell contains very unique cellular machinery that increases the rate of gestation. A few months later, I saw this in action when Candy gave birth to an offspring only 3 months after a recorded mating with Sarina. The offspring was not premature, but completely developed and healthy. So were the next 3 children she had later that year, each of which were born 3 months apart. Two of the offspring were shemales while two were females. DNA tests on the children as well as on Candy and Sarina produced remarkable results. The shemale offspring both had Sarina's unique Z chromosome with the rare traits exclusive to Alpha-Shemales. This might seem like an obvious observation, but none of the shemale offspring Sarina fathered with other women have presented with it. Those shemale babies were average and would grow up to be a basic shemale. But the ones Sarina fathered with Candy are almost guaranteed to grow up to be Alpha Shemales like their father. The female offspring's all show similar DNA to the mother which led me to conclude that they would probably grow up to be Alpha Bimbo's like their mother. 

I've always noticed that most promiscuous women as well as most shemales do not remain in committed relationships. They jump from sex partner to sex partner frequently and without restraint, often maintaining multiple partnerships at once. When females meet Sarina, an Alpha-Shemale, they usually are completely devoted to her, but Sarina still maintains that polygamous mind-set. She has never been with one woman consistently nor does she let them live with her in her home. Yet Candy seems to be the exception this rule. Sure, Sarina still sleeps with countless other women, but Candy remains a constant sex partner. I am not completely sure of the psychological reason for this as Sarina refused to give me a straight answer, but I have formulated a theory based in evolutionary biology. Alpha-Shemales may have an innate 'radar' so to speak that lets them know if a woman is an Alpha-Bimbo. These Alpha-Bimbo's are the most ideal partners for mating. Even though they cannot produce a large litter of offsprings, they instead give birth to other Alpha-Shemales and Alpha-Bimbos. In many ways, they are superior to average humans. Like any speciation event, these two individuals will mate and produce superior offspring that will go forth and breed until they are the dominant species. In other words, I am witness to the birth of a new species that will dominate all of us lesser humans. Who knows if we'll even have a place in this new world as anything but slave labor or sex objects.....And yet, I am perfectly at peace with the though of such a thing occurring.
