Agenital

Agenital is a term for a rare intersex trait under the teresex umbrella in which one is born without visible genitals or without parts of ones genitals, due to being abnormally closed, underdeveloped, or absent (genital aplasia). The condition does not usually occur by itself, but is usually coupled with other conditions.

It may or may not be coupled with gonadal agenesis, gonadal dysgenesis, and/or secondary sex agenesis. The opposite of this condition is macrogenital.

Subsets of this condition are listed and written out below.

Vaginal aplasia
Vaginal aplasia is when someone with a typically female body has little to no genitallia. It is estimated to occur amongst 1 in ever 4,000 AFAB or CTF individuals, and many with this condition seek out surgical assistance later in life (if they weren't altered as an infant) since this isn't always the lack of genitals, and can instead be just very little build to ones genitals.

Labial Hypoplasia
Labial Hypoplasia is a subset of vaginal aplasia in which one is missing one or both labia. It is generally not an issue, as the labia are not essential to urination or sexual activity.

Penile agenesis
Penile agenesis is when someone with a typically male body has little to no genitallia. This is estimated to occur in between 20-30 million AMAB or CTM births. One with this condition almost always needs to have surgical intervention, as they usually have no urinary outlet.

Micropenis
Micropenis is a term for one who has an unusually small penis, usually due to another intersex trait, however this is not always the case. This effects about 0.6% AMAB or CTM individuals. This may be considered a subset of ambiguous genitallia in some cases, and may overlap with clitoromegaly.

Cryptorchidism
Cryptorchidism is when someone with a typically male body is missing one or more testicle, or when one or more of the testicles have formed inside of the body rather than outside. There is currently no findable estimate of this occurence in AMAB or CTM births. One with this condition likely also has hypospadias.

Monorchidism
Monorchidism is a subset of cryptorchidism in which one only has a single testcicle. One with a singular testicle can still be functional enough to produce enough testosterone and sperm to induce pregnancy and fertility.

Microorchidism
Microorchidism is a subset to cryptorchidism in which one has unusually small testicles. One with this condition typically has a lack of masculine horomones released due to the decreased size and functionality, which often leads one to have more feminized traits.

Aphallia
Aphallia is a term for someone who is born without a phallis. This includes Penile agenesis while also including those with a typically female body (AFAB or CTF) who are born without a clitoris. It is a rare condition with very little reports, however this is likely due to fear of stigmatization, since intersex conditions are often looked at in a negative way.

Urethral Agenesis
Urethral Agenesis is a term for someone who is born without a urethra. This can effect both CTM and CTF people, and may be a partnered conditions with other forms of agenital.

Those with this condition may or may not be born without a bladder as well (bladder agenesis.) Surgical intervention is often needed, otherwise the urine may come out of the anal area instead, possibly causing many medical issues.

Other Definitions
Agenital is sometimes used interchangeably with angenital, which is an altersex identity in which one desires to be without genitals.

It is occasionally used to refer to asexuals who are repulsed by genitalia but are not necessarily not devoid of sexual feelings or repulsed by other sexual acts that do not primarily involve genitals.
