During early fetal development, the undifferentiated gonads can develop into either testes or ovaries. The presence of the Y chromosome leads to the development of testes. The testes then produce testosterone, which is converted to DHT via the enzyme 5α-reductase. DHT is a potent androgen that is responsible for the masculinization of the ...
Progesterone is the most important and only naturally occurring human progestogen. In general, androgens are considered "male sex hormones", since they have masculinizing effects, while estrogens and progestogens are considered "female sex hormones" although all types are present in each sex at different levels.
The individual's gonads do not have two X chromosomes, so the breasts will not develop and the uterus will not grow and menstruate until estrogen is administered. This is often given transdermally. Their gonads cannot make progesterone, so menstrual periods will not be predictable until progestin is administered, usually as a pill.
A gonad, sex gland, or reproductive gland [1] is a mixed gland and sex organ that produces the gametes and sex hormones of an organism. Female reproductive cells are egg cells, and male reproductive cells are sperm. [2] The male gonad, the testicle, produces sperm in the form of spermatozoa. The female gonad, the ovary, produces egg cells
If SRY exists, then the gonads develop as testes, and commence the production of androgen hormones, mainly testosterone, dihydrotestosterone (DHT) and androstenedione; production of testosterone and conversion into dihydrotestosterone during weeks 6 to 12 of pregnancy are key factors in the production of a male fetus's penis, scrotum and ...
Progesterone is the major progestogen produced by the corpus luteum of the ovary in all mammalian species. Luteal cells possess the necessary enzymes to convert cholesterol to pregnenolone, which is subsequently converted into progesterone. Progesterone is highest in the diestrus phase of the estrous cycle.

[34] [35] Imaging can include a pelvic ultrasound or MRI, which would reveal normal internal genitalia such as a uterus but with streak gonads, which can be small and thus not easily visualized. [36] Genetic testing involves chromosomal analysis via karyotype to confirm XX chromosomes, rather than XO or XY as discussed in related syndromes above.
