Because society is a very cruel place to live, and many people mistreat those they don't understand. It can be very difficult to go through life coming to terms with being transsexual, and going through the oftentimes difficult process of transitioning genders. When ignorant people make that process even more difficult, it can just get to be too much to deal with, and some people, unfortunately, feel that they can't go on, and choose to end their lives to escape it. There's no excuse for hate and prejudice - and no one has the right to tell another person how to live, or to treat them poorly because they're different from you.
Transsexuals can be male OR female.
Yes. Male to female transsexuals are likely to do it.
They can be either. There are male to female (MTF) transexuals and female to male (FTM)
No
Male to Female transsexuals cannot give birth, however they can have sperm frozen (just like any other biological male) and have children (with a biological female) via insemination or IVF treatment. Female to Male transsexuals can (and do) get pregnant and give birth, as long as they haven't had any genital transgender surgery, and they reverse some of their hormonally induced changes - that means stopping Testosterone and taking female hormones to naturalise their body to that of a naturally fertile female.
They mate with female Black Widows, and since the male knows that mating with the Black Widow will ultimately lead to his death by cannibalism, the black widow technically commits suicide just for the Black Widow spider to live and pass on.
It is a condition where there is a brain body mismatch. Where your physical sex does not match up with your mental/spiritual gender. It has been shown through brain scans the Male to Female Transsexuals have the brains of a woman, and we cannot change that. Instead we adjust the body to the best woman's body we can give them. In the case of Female to Male Transsexuals the reverse is true.
It depends on what you're asking exactly. Male to female transsexuals may be able to impregnate a woman providing that they have not been castrated and that hormone therapy has not rendered them sterile. Female to male transsexuals cannot impregnate women or be impregnated without the use of an outside sperm donor.
Female
Transsexual men wear tuxedos when they get married, generally speaking. Transmen are Female-to-Male, or FtM transsexuals. However, Transwomen are Male-to-Female, or MtF transsexuals, and they generally wear a wedding gown on their big day. This is regardless of hormone or surgery status.
Actually, there are not that many more. It is just that male to female transsexualism is more politicized and that female to male transsexuals tend to blend in with men better. If you have any facial hair at all, people assume you are a man, and transsexual men can easily grow facial hair after hormone treatments. Also, in addition to transsexual women, there are many men who pretend to be women but who do not have transsexualism. Those men who wear dresses are assumed to be transsexuals when they are in the separate bracket called transgender instead. Transsexuals are actually not a part of the transgender community, despite whatever propaganda that exists saying they are. Transsexuals are not really the ones pushing to be known as transgendered. That is forced onto most against their wills. Anyway, transsexual men do not have as big a problem of pretenders taking over their community since women are not as sexually motivated to cross-dress. So the pretenders artificially inflate the MtF TS community.
That is called being a "she-male". Most she-males are actually transsexuals, not transgenders (there is a major difference)
