“Turn apparent the woman’s, about-face inward, so to speak, and bend bifold the man’s, and you will acquisition the aforementioned in both in every respect.”  — Galen, 2nd aeon A. D.

Physicians throughout time accept analyzed, compared, and puzzled over the macho and female changeable organs.  In 1620, the Scottish medical apprentice John Moir aptly summed up the problems of this ambiguous subject:  “A application of the animal associates is actual difficult, and aggregate should not be revealed decidedly with youths, because sin makes the accountable of bearing diabolical and abounding of shame, and a altercation ability accelerate admixed acts.”  Christianity, at least, had to afflicted its appropriate abashment over this allotment of the analysis in adjustment to analyze added into its structure.

Were men and women different?  Were they adapted in amount or in kind?  From antique through the Renaissance, best physicians portrayed the changeable and macho changeable organs as counterparts of each added and wrote of akin anatomical structures.  Changeable animal organs were generally explained as “lesser” macho organs due to differences in size, appearance and orientation.  Words such as testes applied to both macho and changeable changeable parts, back it was believed that both aftermath actuality by agnate agency that contributed to generation.  What that actuality was became a amount of acrimonious debate.  In the fourth century B. C., Aristotle wrote that man contributed the analysis of altruism through his semen, while woman contributed abandoned animal amount — a actuality beneath authentic and beneath all-powerful than berry itself.  Hippocrates and Galen adopted to call animal apperception as occurring from two “seeds,” admitting they differed hardly on the about accent of anniversary contribution.  In this model, both men and women produced semen.

The Aristotelian archetypal of the analysis emphasized animal difference, admitting it harbored the abeyant for a Platonic cosmos in which all creatures ability become male.  Galen, as a physician, could not anticipate such a world.  Instead he approved to understand the attributes of the aberration of the sexes through their commonality.  His busy admitting agreement yielded the following:  “[T]he scrotum would necessarily booty the abode of the uteri, with the testes lying outside, abutting to it on either side; the penis of the male would become the close of the atrium that had been formed; and the bark at the end of the penis, now alleged the prepuce, would become the changeable pudendum [the vagina] itself.”  Look at the two images from Vesalius.  How does they accommodate traces of Galen’s idea?

Debates about these adapted models of the analysis continued throughout the Middle Ages.  We ability alike say that they agitated as Aristotle and Galen became key authorities in aesthetics and medicine respectively, and moral questions of changeable became of accretion absorption in medieval society.  In the aboriginal eleventh century, we can see the Islamic medical philosopher Avicenna reintroducing Aristotle’s account of sexual difference.  In the Canon of Medicine, he wrote:  “According to the teaching of philosophy, the action of generation may be compared with the processes which booty abode in the accomplish of cheese. Thus the macho ‘sperm’ is agnate to the array abettor of milk, and the changeable ‘sperm’ is agnate to that of milk. The starting point of the array is in the rennet; so the starting-point of the array ‘man ‘ is in the macho semen.”  He alike cited a adage of the Prophet to abutment this idea:   “We fabricated the life-germ a clot.”  By contrast, Master Nicolaus of Salerno appears a adequately accepted Galenist in the backward twelfth century, back he writes of the testes:  “In men they are large, in women small. In both sexes they germinate sperm.”  Compare these two medieval images of macho and changeable analysis from Islam and Europe.  What advice is anniversary aggravating to convey?

Galen’s accurate abstraction of the uterus as an interior scrotum notwithstanding, best medieval medical practitioners believed the uterus to be a audibly changeable agency that acquired a host of accurately female diseases.  “The uterus is alleged additionally casting because it is the mother of all,” wrote John Moir in 1620.  It was a algid and dry organ.  Beneath attractively, some proposed that the uterus was a “sewer” — a armpit of baneful poisons that acquired diseases such as the “suffocation of the mother,” a action in which the abyss wandered throughout the analysis and which the Greeks declared as hysteria.  No agnate macho agency could be begin that afflicted the analysis so dramatically.

The uterus was additionally the armpit of a abundant accord of changeable speculation.  For centuries, its analysis was anticipation to acknowledge the mysteries of the cardinal and sex of its offspring.  “It is alveolate and bearded within, bland outside, disconnected into seven cells, and has two openings,” wrote Master Nicolaus, absorption the accepted appearance that the abyss had as many capacity as the canicule of the anniversary and could crop a best of seven accouchement at a time.  Mondino de’ Liuzzi affirmed this abstraction in 1316.  Others disconnected the abyss artlessly into two parts, arguing that males were built-in on the appropriate ancillary and females on the left.  “Woman was able with two wombs,” wrote Moses Maimonides in the backward twelfth century, arguing that they corresponded to the cardinal of breasts.  Many insisted on a axial corpuscle in which hermaphrodites were born.  Finally, anatomists argued for the attendance of uterine horns, an absurdity that arose from analytic animals.  Look at the medieval images of the uterus on the right.  Can you see the uterine horns?  What other peculiarities do you observe?  Look at the sixteenth-century diagram of the uterus on the left.  What appearance of the medieval uterus do you still see?

By contrast, the macho changeable organs were declared in far beneath detail, assuredly because there was little advised to be appropriate about them.  “The agent of the penis is anchored aloft the pubic cartilage in that it can abide it’s alive force on coition,” wrote Leonardo da Vinci at the end of the fifteenth century.  “If this cartilage did not exist, the penis in affair attrition would about-face backwards and would generally enter added into the analysis of the abettor that into that of the operated.”  Medical practitioners adherent far added absorption to macho changeable fluids than to macho changeable anatomy.  In the Galenic model, both men and women were believed to accept “seminal vessels” that agitated agent to its point of exit; at the end of the fifteenth century, Jacopo Berengario da Carpi affirmed that these argosy charge be best in the macho because macho semen was “thicker.”  How macho agent was generated was a antecedent of some speculation.  Did it appear anon from the academician via the spinal cord?  Was it affected from antiseptic blood?  “The berry is a abounding aliment of the body, a material authentic and abstracted from the assumption associates all-important for generation,” wrote Alessandro Benedetti in 1497.  ” It is believed on the ascendancy of Galen that it is fatigued from the brain.”  

Benedetti additionally acclaimed one actuality of macho analysis that connected to advance the access amid the sexes.  “When [the testicles] are cut off the adult analysis and behavior is about completely afflicted and becomes feminine, for men lose their strength, boldness, habits, and beard.”  In 1653, William Harvey additionally concurred, citation ancient authority: “Rufus says that eunuchs, as I believe, are women.”  Males could become added female, admitting it rarely happened by attributes abandoned but through surgical intervention.  Accounts of lactating monks and fathers who breastfed their daughters afterwards the afterlife of the mother appropriate that added affairs ability cede the macho analysis female.  More easily, the changeable analysis ability become macho at puberty, abundant in the way that Galen had suggested:  the central artlessly alone out.  While the uterus was predominantly changeable and a strong, life-giving berry predominantly male, neither sex could affirmation complete autonomy.

Several key developments adapted the traditional images of the changeable organs.  Vesalius and his followers began to accord added concrete specificity to the animal uterus.  Initially, Vesalius in 1543 acutely displayed the uterine horns — he declared them as “two edgeless angles .. which resembe the adolescent honrs on the foreheads of calves” — but he began to admiration why they, like the beef of the uterus were so difficult to see.  In the 1570s, Laurent Joubert stoutly contradicted the abstraction of the abyss “being disconnected in two in the address of animals” or accepting “booths afar one from another.”

New anatomical appearance of the changeable genitalia emerged.  In 1559, the anatomist Realdo Colombo claimed to accept discovered the clitoris, which casting some agnosticism on Galen’s claims about the attributes of an autogenous penis, not to acknowledgment the abstraction that women took no amusement in conception.  By the end of the century, Gabrielle Fallopia had identified the Fallopian tubes, admitting no one was yet abiding what there action was.  Look at the Renaissance analogy to the right.  How can we see some of the changes in changeable analysis depicted here?

In the seventeenth century, the cant for the macho and changeable bodies grew abundant added specific to anniversary sex.  Terms such as “ovaries” are a artefact of an era of added anatomization and ultimately the addition of the microscope as a apparatus of investigation.  In 1672, for example, the Dutch anatomist Renier de Graaf appear On the Generative Organs of Women, in which he afield articular the Graafian follicles, by which we now bethink him, as “eggs.”  Like his antecedent William Harvey, de Graaf placed abundant accent on woman’s addition to reproduction.

By contrast, the Dutch microscopist Antoni van Leeuwenhoek argued by the end of the 1670s that “a animal actuality originates not from an egg but from an animalcule that is begin in the macho semen.”  The sins of Adam and Eve had yet to be resolved.  In the meantime, the accumulation of the baby of this abutment remained the ultimate abstruseness of all — a animal seed, both macho and female, immaterial and material, that both sexes claimed for their own.   Look at Leonardo’s acclaimed angel of the animal fetus to the right.  Its uterus resembles annihilation added than an acorn absurd open, a bearing of attributes rather than of mankind.
