a. Cervical mucus changes.
b. Decreased hormonal levels.
c. Increased uterine contractions.
d. Elevated pH levels.

Answer 1

The woman's body helps control the success of the sperm through cervical mucus changes, increased uterine contractions, and elevated pH levels.

Step-by-step explanation:

The woman's body employs several mechanisms to control the success of the sperm.

1. Cervical mucus changes: The cervical mucus becomes thinner and more alkaline, promoting the passage of sperm into the uterus and making the environment more favorable for sperm.
2. Increased uterine contractions: Uterine contractions help propel and guide the sperm towards the oocyte.
3. Elevated pH levels: The alkaline environment created by the elevated pH levels helps neutralize the acidity of the vagina, protecting the sperm and prolonging their survival.
