Sex Determination in Forensic Odontology
SEX DETERMINATION IN FORENSIC ODONTOLOGY

Identification of living beings and dead bodies is of great importance in Forensic science. Sex determination is one of the important steps in establishing identity.
Sex identification in international sports:
In 1932 Helen Stephens and Stella Walsh: Hitler’s Olympics
In 1936 Stella accused Stephens of being male and so a crude physical examination including gross physical examination of external genitalia was done.
In 1966 gender identification became compulsory in the form of gynecological examination: nude parades – Irina and Tamara Press
In 1968 Olympics, barr body detection was introduced and widely proclaimed to be the solution to gender misinterpretation in sports. This was the simpler, objective and more dignified test involving the cytological analysis of the buccal smear. First detected by Murray Barr in 1948 during research on the nervous system of cats – cells were analyzed following electrical stimulation and a dark body was found in the nucleus of certain animals. This distinction was found to be related to sex & found in human autopsies as well. These nuclear findings came to be known as BARR BODY found associated with only XX sex chromosome, related to the chromatin clump which occurs due to the inactivation of the other paired sex chromosome.
Ewa Klobukowska first polish sprinter to be disqualified following Barr Body examination.
Created more problems than it solved. Gender identification purely via a chromosomal test failed to interpret the complexity of sex determination. Females having complete androgen insensitivity syndrome were barred because of a XY chromosome inspite of complete female phenotype whereas those with Kleinfelter’s syndrome having XXY chromosome had an unfair advantage because of their physique.
In 1991, Barr Body examination replaced by PCR for the SRY locus performed on DNA obtained from buccal smears. All women were screened from 1992 Olympics onwards. None were reported

    Congenital Adrenal Hyperplasia is a form of intersexualism in which a genetic female has internal female sexual structures but masculinized external genitals. Androgen-insensitivity syndrome is a form of intersexualism in which a genetic male is prenatally insensitive to androgens such that his genitals are not normally masculinized. Dominican Republic Syndrome is a form intersexualism in which a genetic enzyme disorder prevents testosterone from masculinizing the external genitalia. CAH is caused by exposure to androgens which are produced naturally through adrenal or mothers may have received synthetic androgens to prevent miscarriage in women who have a family history of miscarriages. Research has been done on CAH and results have shown that girls with CAH act more like a boy. They are more interested in masculine toys such as trucks while girls without are more interested in playing with dolls. Girls with CAH show more aggression in play and tend to have more male friends…

    When the Soho Hospital for Women was set up, and even when this specimen was extracted in the mid-twentieth century, the presence of women in the medical profession was a rarity. Indeed, even now there are few women actually developing medical techniques and devices for the female anatomy. The recognition of women’s skill and ability in the medical professions has been a slow process. Although women have been at the centre of domestic healthcare and midwifery since Antiquity, their ability to enter into academically recognised medical fields as qualified doctors is a much more recent development. Indeed, the surgeon, James Barry (?1792-1865), was actually born Margaret Ann Buckley. She lived as a man during her adult life, rising to become a successful surgeon in the British Army, having graduated from medical school in Edinburgh in 1812 (SM,…

    Each cell in the human body contains a total of 46 chromosomes, 22 of the pairs are the same for both sexes, but the final pair determines whether the individual is female or male. If the embryo is a female the chromosomal pattern will be XX, but if the embryo is male the chromosomal pattern will be XY. The chromosomal make-up of the sperm that fertilises the egg determines an individual’s sex. If the sperm carries an X chromosome, the embryo will be female, but if the sperm carries a Y chromosome the embryo will be male.…

    Forensic science is the uses scientific knowledge to solve legal and criminal investigations by collecting evidence from the crime scene. There are two main parameters that can be used to identify the individual in this case, namely forensic odontology and forensic anthropology. Forensic anthropology identifies human remains especially bones as they could locate and recover suspicious remains to help determine the age, sex, ancestry, stature and features of a decedent from the skeleton. For example, the sex of a person can be determined by studying the base of the skull, the forehead and the jaw. One very efficient method is facial reconstruction. As soon as information such as the race, age and gender are obtained by anthropologists, the artist glues pieces of plastic to the skull at 18-26 key points by using tissue thickness sample charts to identify the victim from the face.…

    The creation of gender has contributed to inequality in American society in many ways. The beginning of this inequality began with Hall. Hall was an intersex human being, born with both male and female parts. Hall was brought forth into the General Court of Virginia because Hall dressed as both men and women when beneficial and “people were confused about Hall's sexual identity” (Kerber 35). In order to find out what Hall's identity was, three women; Alice, Dorothy, and Barbara looked over Hall's body. All three of the women decided that Hall was a woman. In the disagreement over Hall's identity, the owner who was a male named John Tyos, declared he was a male. Now starting from an early time period it showed that even though three women examined…

    The base line of biological influences in gender development is that biological sex is determined by sex chromosomes, XX for female and XY for males. But this approach also argues that genes and hormones are the main influence on gender roles and gender identity in gender development. A research by Ridley has found out that biological sex is determined by a single gene called SRY gene and argued that it also ultimately determines the gender roles and gender identity. When SRY gene is present and functioning normally then this will result in a male otherwise in a female.…

    Sexual differences were the basis of the search for proof of biological differences between races (25). While men were examined, it is in the female body that scientists found differences in sex traits. These studies place black women into the category of abnormal, in comparison to the normal of a white woman (26). This method applies to the sexology studies of the day. Scientists looked for physical differences in the genitalia of homosexual women to categorize them as abnormal.…

    The molding and bending of gender roles in athletics contributes greatly to homophobia. For centuries sports have produced an image of masculinity. Fathers and sons have bonded over athletic prowess in a competitive environment. At a young age, males often use athletics to help create their own gender identity. This sometimes leads to homophobia and prejudice. Males use homophobia in athletics as a way of constructing their male identity especially in front of their piers. Unfortunately for females, their gender roles are somewhat reversed. Women are forced to be careful not to be “too physical” or “too tough”, for fear of people questioning their sexuality (Cashmore).…

    Much as the issue on sexuality remains an unresolved conflict among medical experts, religious and judicial authorities, and hermaphrodites themselves under austere criticism in the 19th century, the search for identity in terms of “true sex” seems far from leaving the mystery which a French rural child of the mid-1900s had originally brought forth. On this ground, there appears no particular border by which we may hold in full recognition the sex of a hermaphrodite in the sense of confident truth especially that Herculine Barbin herself occurred to have not established a definitive claim of what identifies her or where she belongs considering the unity of her biological constitution, nature, and will altogether. While Barbin’s account of personal life was left hanging in non-identity, however, the boy-girl’s manner of presenting her memoirs is rather disposed in its character to lead our study towards an examination of thoughts, feelings, and circumstances which bore significant impact upon her sexuality and psycho-social behavior as a soon-to-be-revealed hermaphrodite.…
