Description:

Ethinylestradiol is a man-made form of the naturally occurring female hormone called oestrogen.

It is prescribed to treat period (menstrual) problems, and also to help ease menopausal symptoms. It is 

usually prescribed alongside another female hormone called a progestogen. 
Ethinyl estradiol also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl? Stradiol, is a 

derivative of 17β -estradiol (E2), the major endogenous estrogen in humans. 

EE is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills. It is 

one of the most commonly used medications for this purpose. 
Estinyl was a preparation of EE alone that was used for the management of menopausal symptoms and 

female hypogonadism. 
EE is released into the environment as a xenoestrogen from the urine and feces of people who take it 

as a medication. 

Application:

Ethinyl estradiol (EE), also sometimes written as ethinylestradiol, ethynyl estradiol, or ethinyl estradiol, is aderivative of 17 beta-estradiol (E2), the major endogenous estrogen in humans. 

EE is an orally bioactive estrogen used in many formulations of combined oral contraceptive pills. It is 

one of the most commonly used medications for this purpose.
Transdermal ethinyl estradiol carries a greater risk of clot formation and venous thromboembolism than 

naturally occurring 17β-estradiol, which some have theorized to be related to different amounts of hepatic 

metabolism after absorption. The same contraindications and precautions apply for EE as with other 

estrogen medications.
