Abstract:
Unintended pregnancy continues to be a serious public health issue in the United States. Of the 3 million unplanned pregnancies per year, 60% occur in women using some form of contraception. Educating and helping women choose a contraceptive agent that best suits their needs will improve compliance and contraceptive efficacy. A multitude of new contraceptive agents are now available. We review new hormonal contraceptive options and discuss newer oral agents, extended-cycle contraception, and innovative delivery methods.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH release.

Hormonal Control of the Ovarian Cycle
Before puberty, the hypothalamus releases GnRH in a low frequency, low amplitude pulsatile manner. This along with the immature hypothalamic-pituitary-gonadal axis activity, results in low estrogen levels and the absence of a fully functional ovarian cycle. At puberty, GnRH secretion increases in both frequency and...
