Sure, I can help you with that. Here is a user-defined function in Python that fulfills the given requirements:

```python
def passenger_details():
# Step 1: Get the number of passengers
num_passengers = int(input())

# Step 2: Create a dictionary to store passenger details
passengers = {}

# Step 3: Iterate over the number of passengers and collect their details
for _ in range(num_passengers):
name, age, gender, aadhaar, pickup, destination = input().split()
passengers[aadhaar] = {
'name': name,
'age': int(age),
'gender': gender,
'pickup': pickup,
'destination': destination
}

# Step 4: Count the number of male and female passengers
male_count = 0
female_count = 0
for passenger in passengers.values():
if passenger['gender'] == 'male':
male_count += 1
elif passenger['gender'] == 'female':
female_count += 1

# Step 5: Display the count of male and female passengers
print('male', male_count)
print('female', female_count)

# Step 6: Fetch passenger details for a specific pickup location
pickup_location = input()
found_passengers = []
for passenger in passengers.values():
if passenger['pickup'] == pickup_location:
found_passengers.append(passenger)

# Step 7: If pickup location is found, display name and age of passengers
if found_passengers:
for passenger in found_passengers:
print(passenger['name'], passenger['age'])
else:
print('not found')

# Step 8: Given an aadhaar number, display pickup and destination location
aadhaar_number = input()
if aadhaar_number in passengers:
passenger = passengers[aadhaar_number]
print(passenger['pickup'], passenger['destination'])
else:
print('not found')

# Call the function to execute the code
passenger_details()
```

Please note that this code assumes the input is provided in the specified format.
