17-AH Deficiency

17-AH Deficiency or 17-alpha-hydroxylase deficiency is an intersex variation in which the adrenal glands- the glands that regulate the production of certain horomones- do not properly function. Because of this, the reproductive system does not grow very strongly. This condition is estimates to effect 1 in a million individuals at birth.

Those with XX chromosomes (CTF) have abnormally small ovaries and an abnormally small uterus. Because of this, they do not develop many secondary sex traits, such as breasts, pubic hair, or menstruation cycles. From this, they are unable to conceive a child, and thus are infertile, and usually also fall under AFAB Hypogonadism.

Those with XY chromosomes (CTM) usually have ambiguous genitals or a vagina, and because of this, they are often mistaken as female. Those that do have a penis often have a micropenis, cryptorchidism, and/or hypospadias. They are also infertile, and often fall under AMAB Hypogonadism.

It is important to note that not all the symptoms listed above are guaranteed to occur in someone with this variation, as someone may only experience one or several of these symptoms, yet still hold the variation.

Genetics
This variation is inherited in an autosomal recessive pattern, which means both parents have a copy of the gene mutation that causes this, and both of their genes combined is what effected the child when being conceived.

Flag
The flag was coined by Anderson from Cryptocrew's system on April 35th of 2021. Blue represents male-like traits, pink represents female traits, purple represents ambiguous traits, yellow represents diversity, white represents community, black represents abnormalities in size, and the black design is designed to resemble the uterus/ovaries and/or the male reproductive system/testicles.

The alternate flag was coined on the same day by Anderson, with the same meanings.
