Mucous Method for Fertility

The Mucous Method for Fertility Detection: Infertile mucous is described as sparse, thick, flaky, crumbly, dense, opaque, pasty and tacky. It is unchanging in amount. It does not string when you separate your finger and thumb. The mucous increases and decreases as estrogen levels rise and fall. After ovulation, the luteal phase, where the ovary produces more progesterone, lasts 12-16 days. During this time the mucous reverts to the sparse, thick, tacky consistency. Sperm cannot survive in this mucous.
