Like most hormones in the body, sex hormones are steroids. They are called that because they are chemically related to cholesterol.

Androgens and estrogens are hormones. Examples of androgens are testosterone, dihydroxytestosterone, and examples of estrogens include estradiol.
The simple answer would be estrogens. In reality, however, the adrenal glands produce actual estrogens in minute amounts only. Instead, they release the precursor molecules of the sex hormones into the bloodstream, and the gonads - testes or ovaries - convert these into testosterone and estrogens, respectively.
These hormones are produced mainly by the endocrine glands. The endocrine glands in females are ovaries and those in males are testes. While both males and females have all types of hormones present in their bodies, females produce the majority of two types of hormones, estrogens and progesterone, while males produce mainly androgens such as testosterone. Most androgens produced by females are converted to estrogens and some androgens in males are also converted to estrogens.
Testosterone
The hormones that most dramatically affect breast growth are estrogens.
The adrenal gland of females produces some androgens. This affects libido. In males, estrogens are precursers to testosterone during its synthesis.
testosterone
The testes produce the male hormone testosterone and therefore the body no longer produces this whether done by surgery or chemically
Prescription-strength natural hormones usually are produced from stigmasterol extracted from soybeans. They are chemically altered so as to be bioidentical to human forms such as progesterone or the human estrogens.
The ovaries secrete progesterone and Oestrogen, the testes secrete testosterone and oestrogen. These are known as androgenic hormones.
