Purpose:
The purpose of this survey was to quantify oral contraceptive pill (OCP) use and to analyze attitudes and knowledge about the pill in a sample of female medical students.
Methods:
A cross-sectional study, conducted between November 28 and December 20, 2011, included 464 female participants from the Faculty of Medicine, University of Belgrade. Data were collected before the start of compulsory practical sessions in the classrooms through a 37-item questionnaire and assessed statistically.
Results:
Prevalence of OCP use was 11.3 %. Highest proportion of the pill use was in the third year (15.4 %). Approximately, 61 % used the pill as a therapy for dysmenorrhea. Difference in knowledge scores was observed between users and non-users (t = 3.596, p < 0.001). Advancing year at the faculty was highly statistically significantly associated with greater knowledge about health effects of the pill (ρ = 0.506, p < 0.001). There was no difference regarding attitude score among users and non-users (t = -0.9, p = 0.369). In the multivariate regression model the knowledge score was the only predictor of pill use.
Conclusion:
The results of our survey indicate that oral contraceptive pill requires further promotion and reproductive health education in a broader context.

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...
