Where in the cell are steroid hormones synthesized?

Steroid hormones are synthesized in the smooth endoplasmic reticulum (SER) of cells, particularly in steroidogenic tissues such as the adrenal glands, ovaries, and testes. The synthesis process involves the conversion of cholesterol into various steroid hormones through a series of enzymatic reactions. Additionally, mitochondria play a crucial role in the initial steps of steroidogenesis by facilitating the transport of cholesterol into the steroidogenic pathway.
