Abstract:
Progress has been made in efforts to reduce unintended pregnancy; however, unintended pregnancy remains a public health issue in the United States. A key component of reducing unintended pregnancy is to increase correct and consistent use of contraception by reducing barriers to access and use. The CDC has recently updated its guidance for the safe and effective use of contraception. The U.S. Medical Eligibility Criteria for Contraceptive Use (US MEC), 2016, and U.S. Selected Practice Recommendations for Contraceptive Use (US SPR), 2016, are intended for healthcare providers to help patients choose a method that is safe and can be used effectively. The recommendations aim to reduce certain barriers to contraception and thus help women, men, and couples to control timing of pregnancies.

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...
