D
As the woman nears ovulation, estrogen causes the cervical mucus to become clear, thin, and stretchy. This type of mucus provides a favorable environment for the sperm and helps their motility toward the ova. Immediately after ovulation, the cervical mucus becomes hostile to sperm. It becomes thick, cloudy, and more acidic. It also loses its stretchiness.
