Options

A. Day 18
B. Day 14
C. Day 1
D. Day 8

Answer

To determine the approximate day of ovulation in a fertile human female with a menstrual cycle of 32 days, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Menstrual Cycle Duration**:
- The average menstrual cycle lasts about 28 days, but in this case, we are considering a cycle of 32 days.

2. **Identify the Ovulation Timing**:
- Ovulation typically occurs around the midpoint of the menstrual cycle. In a 28-day cycle, ovulation occurs around day 14.

3. **Calculate the Midpoint for a 32-Day Cycle**:
- To find the midpoint of a 32-day cycle, we divide the total days by 2:
\[ \text{Midpoint} = \frac{32}{2} = 16 \]
- This means ovulation will occur around day 16.

4. **Consider the Range of Ovulation**:
- Ovulation can occur a couple of days before or after the midpoint. Therefore, for a 32-day cycle, ovulation may occur between day 16 and day 18.

5. **Select the Correct Option**:
- If we look at the options provided, day 18 falls within the range we calculated (16 to 18). Hence, day 18 is the most appropriate answer.

### Final Answer:
- Ovulation in a 32-day menstrual cycle occurs approximately on **day 18**.
