Cervical mucus changes and ovulation prediction and detection
Abstract:
Cervical mucus can be used to predict ovulation if a woman has received adequate education in the method and is committed to careful observation of her cervical mucus changes. Many different tests have been based on the quantity, physical properties or biochemical constituents of cervical mucus. However, routine use of cervical mucus for ovulation monitoring by patients requires that the tests be more practical for accurate sample collection and more objective for the detection of cervical mucus changes.

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.
