How does Diane-35 work as a contraceptive Pill?
The cyclical production of the female hormones and the maturation of a follicle (egg) in the ovaries are controlled by a small organ (size about 1 cm) connected to the brain, the pituitary gland. Diane-35 meanwhile contains two female hormones, estrogen and progestin. These are similar to the natural hormones women produce in their ovaries. The pituitary gland is not able to distinguish the hormones contained in Diane-35 from those produced by the ovaries. It, therefore, stops inducing the natural hormone production by the ovaries and eventually the process of egg growth and release. This hormonal feedback mechanism is based on the same principle which blocks the maturation and release of further eggs during pregnancy.
