Sincerely,
'In
modern medical terminology, 'cervix' is understood as meaning the short,
thick tube of smooth muscle which surrounds the narrow channel (the endocervical
canal) which leads from the vagina through to the uterus. The lower end
of the cervix dips into the vaginal chamber, and is called the external
os (opening, or mouth), while the upper uterine end of the cervix is known
as the internal os. The intimate connection between the cervix and the uterus
is highlighted in the full title of the cervix, the cervix uteri, which
means the neck of the womb or neck of the uterus.' (Blackledge, p. 64, 2004)
'Curiously though, the word cervix does not mean neck. Collum is the Latin for neck. The source of the word cervix lies, surreally, in the curving, cresent-shaped horns of many mammals. And curiously, although this horn meaning was somehow lost in human anatomical vocabulary, it survives today in animal physiology. A cervid is any ruminary mammal of the class Cervidae, mammals that are characterised by the presence of horns or antlers.' (Blackledge, p. 64, 2004)
'The conception of the Fallopian tubes as horns of the uterus is easily understood. A look at any modern illustration of a woman's uterus reveals the source of the idea. Fallopian tubes do trace a graceful horn-like curve, and are positioned in conjunction with the uterus in such a way that it's not too fanciful to see them as mirroring the horns and antlers of deer or bulls.' (Blackledge, p. 65, 2004)
A very interesting essay from the journal of Evolutionary Psychology on evolutionary strategies in humans for successful fertilization.
From the essay: 'Magnetic resonance imaging studies show that during coitus, the typical penis fills and expands the human vagina, and with complete penetration often pushes up against the cervix. When ejaculation occurs, thrusting diminishes and vaginal penetration reaches its maximum point (Masters and Johnson, 1966). Not only does this serve to release semen in close proximity to the cervix, but data on ejaculatory pressure shows that the first several ejaculatory contractions project seminal fluid with such force that it can be expelled at a distance of 30-60cm if not contained in a vagina (Masters and Johnson, 1966). Thus, there appear to have been a series of adaptations that serve to confine or focus the release of semen to the uppermost portion of the vaginal tract, possibly as a means of making it less vulnerable to displacement by other males. A longer penis would not only have been an advantage for leaving semen in a less accessible part of the vagina, but by filling and expanding the vagina it also would aid and abet the displacement of semen left by other males as a means of maximizing the likelihood of paternity.'

Want to be Involved? Join us in this research,
which provides an excellent opportunity to present to the world the latest
knowledge about the thing we all find most interesting - sex! The work will
not just benefit humanity, it will profoundly enhance your own sexuality
as you learn more about our complex and diverse sexual evolution.
We seek help in finding the latest scientific (evolutionary)
research on our biological and cultural sexual evolution and distributing
content (overviews / summaries) to relevant pages.
This site is well respected. We are listed as the
Top
Philosophy Website on the Internet with around 600,000 page views each
week. So your contributions will be seen and read, and will be providing
humanity with a great source of wisdom about a very important subject (that
currently suffers due to cultural / religious myths).
If you would like to be involved (or have comments about this website) please
write to us.
Many thanks! Karene
Analyse
any human emotion, no matter how far it may be removed from the sphere of
sex, and you are sure to discover somewhere the primal impulse, to which
life owes its perpetuation. ... The primitive stages can always be re-established;
the primitive mind is, in the fullest meaning of the word, imperishable.
... Mans most disagreeable habits and idiosyncrasies, his deceit, his cowardice,
his lack of reverence, are engendered by his incomplete adjustment to a
complicated civilisation. It is the result of the conflict between our instincts
and our culture. (Sigmund Freud)
