Abstract:
25 ovariectomized women mean age 47 +/- 5 years were treated with transdermal 17 beta Estradiol in the shape of Estraderm TTS 100 plasters. Drugs were administrated in 28 days cycles during 24 weeks. Chlormadinon in daily dose 2 mg was added from 16 to 28th day of the fourth therapeutic cycle. Total cholesterol, triglycerides, HDL and LDL fractions were checked using enzymatic method. First measurement was done before the treatment, the next in the last day of every cycle. Results were statistically analysed. After treatment there were significant increase in the mean values of HDL, significant decrease of triglycerides. Changes in mean level of LDL and total cholesterol were not statistically significant. Our results seem to confirm the previous observations concerned with transdermal estrogen replacement therapy and its efficacy in atherosclerosis prophylaxis.

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.
