Final answer:
The thinning of the cervical mucus near ovulation creates a favorable environment for sperm motility, aiding its passage through the cervical canal and increasing the likelihood of fertilization.
Step-by-step explanation:
The feature of cervical mucus near ovulation that provides a favorable environment for sperm and helps their motility to the ova is that the mucus becomes thin. As ovulation approaches, the cervical mucus becomes thinner, which facilitates sperm passage through the cervical canal. Additionally, the mucus becomes more alkaline, which makes the environment more hospitable for sperm survival and movement. This process is part of preparing the sperm for fertilization through capacitation. The cervical changes also include widening of the cervical canal to further aid the passage of sperm.
