Hormone stéroïdienneLes hormones stéroïdiennes sont des stéroïdes se comportant comme des hormones. On peut les regrouper en cinq catégories selon leurs récepteurs : les glucocorticoïdes, les minéralocorticoïdes, les androgènes, les œstrogènes et les progestatifs. Les dérivés de la vitamine D forment un sixième système hormonal proche des précédents, mais techniquement parlant il s'agit de stérols plutôt que de stéroïdes.

It is formulated in combination with a progestin and is not available alone. It is taken by mouth. Side effects of mestranol include nausea, breast tension, edema, and breakthrough bleeding among others. It is an estrogen, or an agonist of the estrogen receptors, the biological target of estrogens like estradiol.
