Objective:
To know the contraceptive use and trends in the Spanish female population.
Study Design:
Since 1997, we have conducted a survey every 2 years on the use of contraceptive methods among a representative sample of Spanish women of childbearing potential (15-49 years).
Results:
In the period 1997-2003, the percentage of use of contraceptive methods in Spain rose from 55.6% to 71.2%. The most commonly used method was the condom (21% in 1997, 21.9% in 1999, 29.5% in 2001 and 35.7% in 2003), followed by the contraceptive pill (14.2%, 16.5%, 19.2% and 18.3%, respectively). Male or female sterilization remained stable with percentages of use of 5-7%. IUDs are used by about 5% of women.
Conclusions:
The use of contraceptive methods among Spanish women of childbearing potential generally fits quite well the patterns found in other developed countries, and we observed a trend towards increased use of effective 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.
