Marvelon®, introduced by Organon in the early 1980s, is a monophasic combined low-dose oral contraceptive containing 150 microgram desogestrel (one of the first modern progestogens to become available) and 30 microgram ethinylestradiol.

In 1998 cumulative sales of Marvelon and other oral contraceptives containing desogestrel exceeded one billion worldwide, confirming its acceptability and safety.

Marvelon was approved for use in the USA in 1992, under the trade name Desogen®. It was among the first modern pills to be available to women in the USA.
