Sexual Dictionary - letter T

T cell
type of lymphocyte that are produced in the bone marrow and mature in the thymus, that activate the rest of the immune system a nd directly attack virus-infected cells, foreign cells, and cancer cells. T cells also produce a number of substances that regulate the immune response. The abbreviation T stands for thymus, the organ in which their final stage of development occurs. In the course of HIV infection T cells are damaged thus the body immune system is weakned and cannot longer defens against opportunistic infections. T cells are also called T lymphocyte.
Tampon
an especially designed plug of absorbent material(cotton, rayon, or a blend of the two) for inserting into vagina to absorb the flow of blood during menstruation or to absorb secretions. The tampon has a cylindrical shape and comes in various sizes, which are related to their absorbency ratings. They have a string for ease of removal, and may be packaged inside an applicator to aid insertion. Tampon applicators may be made of plastic or cardboard, and are similar in design to a syringe. The tampon rests inside a hollow tube, which has a narrower tube nested inside one end of it. The open end of the applicator is placed and held in the vagina, then the woman presses the narrower tube in with her fingers. The narrow tube slides into the wider tube, pushing the tampon through and into the vagina. Tampons sold without applicators are simply unwrapped and pushed into the vagina with the fingers.
A tampon must be replaced at least every six hours even there no blood absorbsion. If left in place more than six hours may lead to the risk of toxic shock syndrome. The link between TSS and tampon use is unclear. Research suggests that for cases which occur in women using tampons, tampon absorbency is a factor because their prolonged intra-vaginal use enhances the bacterial growth. For this reason it is important that always use a tampon with the lowest absorbancy suitable for the period flow, use a sanitary towel or panty liner from time to time during period or during night, and change tampons regularly.
Vaginal dryness and ulcerations may occur when women use tampons more absorbent than needed for the amount of their menstrual flow. Ulcerations may also occure in women using tampons between menstrual periods to try to control excessive vaginal discharge or abnormal bleeding. Women may avoid problems by choosing a tampon with the minimum absorbency needed to control menstrual flow and using tampons only during active menstruation.
When using tampons, it is also important to remember to wash hands before and after inserting a tampon, never insert more than one tampon at a time, remove the tampon at list once in six hours.
Testicle
the male sex gland. There are a pair of testes behind the penis in a pouch of skin called the scrotum. The testes make and store spermatozoa, and make the male hormone testosterone. Known medically as testes (singular testis).
Testosterone
male sex hormone (androgen) made primarily in the testicles. It is responsible for the development of the male reproductive organs, the development and the release of spermatozoa, male physical characteristics, stimulates blood flow, stimulates sexual activity, growth in certain tissues and the secondary sexual characteristics. Small amounts of testosterone are also produced in women by the ovaries and the adrenal glands.
Thrush
see candidiasis.
Thymus gland
a gland that found in the upper chest behind the sternum (breastbone) in which T cells grow and multiply after they leave the bone marrow. The gland grows throughout childhood until puberty and then gradually decreases in size.
Thyroid gland
a gland situated in front and on either side of the trachea (windpipe) and is part of the endocrine system. Secretes various hormones (most important is thyroxine) which are released into the bloodstream and helps regulate body normal growth and metabolism.
Topless
the lack of clothing covering the breasts. It is used especially in reference to females. It is a form of nudity which can be taken (or not) as indecent exposure, according with the local custom and law, the conventions of a particular culture and situation.
Toxic shock syndrome
toxic shock syndrome (TSS) it is an acute infection caused by a bacteria - Staphylococcus aureus. Another type of toxic shock syndrome it is streptococcal toxic shock syndrome (STSS) that it is caused by an acute infection with a Streptococcus pyogenes, most often a skin infection or an infected wound. Both toxic shock syndromes are characterized by high fever, a sunburnlike rash, weak and rapid pulse, vomiting, and diarrhea, fatigue and weakness, thirst, pale, cool, moist skin, and rapid breathing followed in severe cases by shock, that is caused by the toxins that are released into the body by the bacteria.
Toxoplasmosis
an oppotunistic infection due to the microscopic parasite named Toxoplasma gondii. The parasite is carried by cats, birds, and other animals, and is found in soil contaminated by cat f eces and raw meat. The parasite can infect the lungs, retina of the eye, heart, pancreas, liver, colon, and testes. Once it invades the body, it remains there, but the immune system in a healthy person usually prevents the parasite from causing disease. If the immune system becomes severely damaged, as in HIV-infected persons, the parasite can begin to multiply and cause fatigue, headache, swollen lymph glands, and muscle aches and pains. It may cause stillbirth or miscarriage, blindness, retardation, and neural tube defects in the fetus if a woman contracts it for the first time during pregnancy. Exposure prior to pregnancy creates immunity but most women are routinely screened for toxoplasmosis in early pregnancy to determine immunity. People can get infected by eating raw meat or by contact with cat faeces. To reduce the risk of infection, people should avoid touching a cat's litter tray, always wash hands after handling meat or gardening, not eat undercooked meat.
Transsexual
a person who believes that psychologically does not match the sex that was assigned to he or she at birth and wants to be considered by society as a member of the opposite sex. A transsexual may seek medical help to surgically change the genitals and other aspects of appearance to match the deeply felt internal gender identity.
Transsexuality
the behavior of a person whose sexual identification is entirely with the opposite sex. Transsexuality it is not synonym with homosexuality because the gay man's sexual identification is with a man and a lesbian's sexual identification is with a woman.
Tribadism
human sexual behavior where two women simulates heterosexual intercourse and rub their external genitalia against one another for clitoral stimulation.
Trichomoniasis
a sexually transmitted disese of the vagina. It is caused by the parasite named Trichomonas vaginilis. In women, tricomoniasis can cause urinary tract infection and a painful, malodorous vaginitis marked by a thin, foamy, irritating discharge. Can cause premature birth in pregnant women. In men, it can infect the urethra and bladder. Most men have no noticeable symptoms, an important factor in its easy transmissibility. Because trichomoniasis wide spread and because it often doesn't produce symptoms, it is very important to take precautions by practicing safer sex.
Troilism
sexual activity involving three people.
Tubal ligation
a surgical procedure for female sterilization in which the fallopian tubes are cut and tied off preventing spermatozoa and eggfrom meeting and preventing the fertilization. It is a permanent form of birth control.
Tumor
abnormal mass of tissue that results from excessive cell division. May be benign or malignant. Tumors perform no useful body function.
Also called neoplasm.
