The relationship between the ratio of E1-3-G/Pd-3-G and the fertile period
Chapter
Abstract
Current methods of monitoring ovulation and the fertile period are imperfect. There is as yet no simple precise marker of ovulation. Modern methods of natural family planning aim to prevent conception by marking the fertile period surrounding ovulation. They are hampered by their subjective and/or retrospective nature. If a simple, reliable and objective marker of both the beginning and the end of the fertile period could be developed, these deficiencies might be overcome. We have investigated the relationship between the E/P index (oestrone-3-glucuronide/pregnanediol-3-glucuronide) and a defined 5 day period surrounding ovulation.
