Evening Primrose Oil  $16.50  Evening Primrose Oil helps the body to produce more fertile quality cervical fluid also known as "egg white cervical mucus." This is because fertile cervical fluid is thin, watery, clear and "stretchy" and easily aids the sperm to swim through the uterus and into the fallopian tube, and to the egg. If there is a lack in this type of cervical fluid, it can impede and/or prevent fertilization. : Average Customer Rating   Quantity:
