Contraception in perimenopause
1From the Rush University Medical Center, Chicago, Illinois.
Abstract:
Perimenopause is characterized by wide hormone fluctuations and irregular menstrual cycles for 5 or more years preceding menopause and lasts until 12 months of amenorrhea have been achieved. It represents a period of reproductive transition with a decline in fertility. However, unintended pregnancies do occur, with a high risk for poor outcomes and maternal complications. All women transitioning through perimenopause should be adequately counseled. There are many hormone and nonhormone contraceptive methods that are highly effective and suited to the personal and medical needs of the perimenopausal woman. Contraception should continue until menopause is confirmed.

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...
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...
