Andro
Short for androstenedione, a normal precursor to testosterone and other androgens. Taking andro can raise testosterone levels. See: Androstenedione.

Androcur
The trade name of the hormone, cyproterone acetate, manufactured by Schering A.G., West Berlin. The hormone resembles progestin and is antiandrogenic. It has various clinical applications, one of which is to help sex offenders gain personal governance of their sexuoerotic conduct.

Androgel

Androgen ablation
Treatment designed to suppress or block the production of male hormones. Androgen suppression can be achieved by surgical removal of the testicles, by taking female sex hormones, or by taking other drugs called antiandrogens. Also called androgen suppression.

Androgen hermaphroditism
Androgen-induced hermaphroditism is a syndrome of hermaphroditic birth defect of the sex organs induced in the 46, XY gonadally female fetus by an excess of masculinizing hormone transmitted from the mother through the placenta. The syndrome may be experimentally induced in animals by injection of the hormone testosterone, whereas in human beings it is adventitious, the source of the hormone being a maternal (possibly placental) hormone-producing tumor.

Androgen hormone
A hormone secreted by the adrenal cortex which affects the development of male characteristics.

Androgen insensitivity syndrome, complete
"A genetic disorder that makes XY fetuses insensitive (unresponsive) to androgens (male hormones). Instead, they are born looking externally like normal girls. Internally, there is a short blind-pouch vagina and no uterus, fallopian tubes or ovaries. There are testes in the abdomen or the inguinal canal. The complete androgen insensitivity syndrome is usually detected at puberty when a girl should but does not begin to menstruate. Many of the girls with the syndrome have no pubic or axillary (armpit) hair. They have luxuriant scalp hair without temporal (male-pattern) balding. They are sterile and cannot bear children. They are at high risk for osteoporosis and so should take estrogen replacement therapy. The gene for the syndrome is on the X chromosome in band Xq11-q12. The gene codes for the androgen receptor (also called the dihydrotestosterone receptor). This gene is mutant in the complete androgen insensitivity syndrome. Because of the mutation, the cells cannot respond to androgen. If a woman has the mutation on one of her X chromosomes, the risk for each of her XY offspring to receive the gene and have the syndrome is one-half (50%). There are also partial androgen insensitivity syndromes. They usually result in micropenis with hypospadias and gynecomastia (male breast development). These conditions (which include a disorder called Reifenstein syndrome) are also due to mutations in the androgen receptor gene. The complete androgen insensitivity syndrome was once referred to as testicular feminization (TFM). The name ""complete androgen insensitivity syndrome"" is scientifically accurate and is more satisfactory to patients and their families."

Androgen suppression
Treatment designed to suppress or block the production of male hormones. Androgen suppression can be achieved by surgical removal of the testicles, by taking female sex hormones, or by taking other drugs called antiandrogens. Also called androgen ablation.

Androgen-insensitivity
The androgen-insensitivity syndrome is a congenital condition identified by a 46, XY sex chromosomal karyotype in girls or women who appear externally to be not sexually different from normal females, except in some cases for a swelling or lump in each groin, or for the absence or sparseness of pubic and axillary hair after puberty. The cells of the body are unable to respond to the male sex hormone, which is made in the testes in normal amounts for a male. They respond instead to the small amount of female sex hormone, estrogen, which is normally made in the testes. The effect before birth is that masculine internal development commences but is not completed. It goes far enough, however, to prevent internal female development. Externally, the genitalia differentiate as female, except for a blind vagina, which is usually not deep enough for satisfactory intercourse and needs either dilation or surgical lengthening in or after middle teenage. There is no menstruation and no fertility. Breasts develop normally. Incidence of occurrence is approximately one in 500 births.

Androgenic
" Pertaining to the development of male characteristics, including body hair, the genital organs and muscle mass. ""Androgenic"" is the adjective form of the noun ""androgen,"" a word referring to any of the male hormones, including testosterone and androsterone. Androgenic development -- that is, the development of male characteristics -- begins in puberty, the time when a person becomes physically capable of producing offspring. In males, this time most commonly occurs between ages 12 and 14. A deepening voice is one of the signs of androgenic activity. Androgen is produced in males by the testes, the two globe-shaped reproductive organs below the penis, and by the adrenal glands, two small hormone-producing organs that each sit atop a kidney. Androgen is also produced in females in the adrenal glands. Overproduction of androgen can generate some male characteristics in women and exaggerate male characteristics in men. ""Androgenic"" is derived from the Greek words ""andros"" (man) and ""genein"" (to produce)."" Related words include ""androgynous"" (having both male and female characteristics), ""andrology"" (the study of health in males), ""androphobia"" (fear of men) and ""android"" (in science fiction, a manlike robot)."

a girl or woman being a person manifesting the features or qualities of a male in bodily appearance, dress and behavior.

Andromimetophilia
A paraphilia of the stigmatic/eligibilic type in which sexuoerotic arousal and facilitation or attainment of orgasm are responsive to, and contingent on a partner who is an andromimetic or, in some instances, a sex-reassigned, female-to-male transexual. The paraphilic counterpart in men is gynemimetophilia.

Androphilia
Love of a man by a woman (female androphilia) or by a man (male androphilia). It includes erotosexual bonding.
