Documented Uses

• For the prevention of pregnancy in women who elect to use this product as a method of contraception.
• Oral contraceptives which owe their effectiveness to hormonal preparations.
• Oral contraceptives which owe their effectiveness to synthetic preparations.
• Binds to the progesterone and estrogen receptors. Target cells include the female reproductive tract, the mammary gland, the hypothalamus, and the pituitary. Once bound to the receptor, progestins like Ethynodiol Diacetate will slow the frequency of release of gonadotropin releasing hormone (GnRH) from the hypothalamus and blunt the pre-ovulatory LH (luteinizing hormone) surge.
