Abstract:
Long-acting, reversible contraceptives are about 20 times more effective in terms of contraceptive efficacy than oral hormonal contraceptives, patch or vaginal ring are. Long-acting, reversible contraceptives are not associated with serious adverse events but induce changes in menstrual bleeding pattern in about 75% of the users. The progestogen intrauterine device is effective in the treatment of menor-rhagia and dysmenorrhoea. Increased use of long-acting reversible contraceptives is expected to reduce unplanned pregnancies and legal abortions in all ages. Concomitant use of barrier methods is important to prevent sexually transmitted diseases.

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...
