Product Description

oral contraceptives ,21+7,medicine factory 
Oral contraceptive pills, the most common pharmaceutical-based contraceptive method, are formulated with synthetic estrogen and progesterone and have an extremely high contraceptive success rate. After years of research and improvement, the side effects of oral contraceptives are now very mild, except for early pregnancy reaction at the beginning. Moreover, if taken regularly over a long period of time, the pill can help to "calibrate" the menstrual cycle.On May 31, 1961, the oral contraceptive pill was approved for use in the United States.
primary function ;
The main effects of contraceptives: to inhibit ovulation and alter the cervical mucus so that sperm cannot easily penetrate, or to cause the uterine glands to reduce the production of heparanose so that blastocysts cannot easily survive, or to alter the way the uterus and the fallopian tubes move so as to impede the transport of a fertilized egg.

Mechanisms of action are multi-part and multi-faceted and vary depending on the ingredients, preparations, dosage and usage they contain. For example, combination preparations of estrogen and progesterone are predominantly ovulation inhibiting, small doses of progesterone are predominantly impeding fertilization, and large doses of progesterone are predominantly antiretroviral. The above categorization of application mechanisms is relative.
