Are there more than two sexes?

Answer 1

In humans, genetically there are technically only 2 sexes or genders. Some, however, nowadays may contend that non-operational transgendered persons constitute a third gender o Male-to-female(MTF) or FTM. This might be considered more of a political or social designation rather than being a purely medical or scientific designation.

So when you read an ad or profile stating someone is of the "3rd gender" it typically refers to a Transgender Person (also often called transsexual, tranny, shemale, ladyboy or newhalf).

Hope this helps

Answer 2

For many years humans were characterized as having only two genders. These were male and female and linked both to the physical organs and the romantic or sexual attraction. People were in general forced into one of these two roles. The term gender was used confusingly between physical and emotional/mental attributes.Sex at the genetic level was determined by X and Y chromosomes. Men were thought to have an x and a Y chromosome, women double X (XX) chromosome. Right away there is a problem as there are six nominations of these karyotype sexes that create viable fetuses:

• X
• XX – female
• XXY
• XY – male
• XYY
• XXXY

With the advent of testing for sex in the Olympics more attention was given to more masculine women who, either by birth or chemical alteration, were more masculine and thought to have an "advantage" over other competitors. Previously at birth a small number children were noted to have either both or poorly formed sex organs and were difficult to classify none or the other binary categories. With regard to sexual preferences most societies have found that sexual preferences by individulas can shift from same ex, to alternate sex, to either see, to neither sex. Most recently individuals who feel they are the wrong sex can convert to the other by surgery/hormone treatment or adopting the appearance or mannerism of the other sex.

As a consequence there can be:

• six chromosomal sexes
• at least three visually apparent birth sexes
  
• at least five partner preference sexes
  
• at least three altered choice sexes
  
• at least five physical/mental sexual matches
