ienogest: the active ingredient is a substance related to the female sex hormone progestin (yellow body hormone).
In women, the progestogen causes, among other things, inhibition of the growth of the uterine mucosa, which prepares for pregnancy, inhibition of sperm transport and inhibition of ovulation.
The active ingredient is a synthetic progestin, which is used alone or in combination with ethinyl estradiol to prevent pregnancy.
It can also be used to treat menstrual problems, acne, and endometriosis in women.
Ethinylestradiol: The active ingredient is a substance associated with the female sex hormone estrogen.
Estrogen causes, among other things, the cyclic buildup of the lining of the uterus in preparation for pregnancy and facilitates the transport of spermatozoa to the uterus.
In particular, ethinylestradiol inhibits the maturation of the egg in the ovary. It also suppresses the hormones that cause ovulation and thus has a contraceptive effect.
Ethinylestradiol is usually used in combination with a progestin (a corpus luteum hormone).
