Spinnbarkeit is the "stringy and stretchy" quality of cervical mucus at the time just prior to ovulation. When a woman is most fertile, the mucus becomes abundant, clear, and stretchable – like “egg white”. Also referred to as “fertile cervical mucus”, it provides an ideal media for sperm. Following ovulation, cervical mucus may become “hostile”, due to the increase of the hormone progesterone and becomes resistant and impenetrable to sperm. By observing the quality of cervical mucus, you can predict when you are most fertile.
Pre-Seed can address the problem of dryness when you are trying to conceive, and products like FertileCM may help women produce abundant, fertile-quality cervical mucus. Both products can work together: Pre-Seed functions by providing sperm-friendly lubrication in the vagina, and FertileCM, containing L-Arginine, is designed to support the production of fertile cervical mucus in the cervix and cervical canal.
