In which of the following animals the sperm can survive for a longer period in the body of female ?

Options

A. Mammals
B. Aves
C. Reptiles
D. Amphibia

Answer

To determine in which of the following animals the sperm can survive for a longer period in the body of the female, we need to analyze the reproductive biology of different groups of animals. Here’s a step-by-step solution:

### Step 1: Understand Sperm Survival
- Sperm survival in the female reproductive tract varies among different species. Factors such as the environment, nourishment, and conditions in the female reproductive system play a crucial role.

### Step 2: Examine Human Sperm Survival
- In humans, sperm can survive for approximately 72 hours (3 days) after ejaculation. However, under optimal conditions, it can survive up to 4 to 5 days in the female reproductive tract. This is due to the nourishment and warm, moist conditions provided by the female body.

### Step 3: Compare with Other Animals
- In mammals, sperm survival can be similar or slightly longer than in humans, but it is generally not significantly longer than 5 days.
- In birds, amphibians, and reptiles, sperm typically has a shorter lifespan in the female reproductive tract compared to mammals. For instance, in many birds, sperm may survive only a few days.

### Step 4: Identify the Correct Answer
- Since the question asks for the animal in which sperm can survive for a longer period, and considering that humans (mammals) have one of the longest sperm survival times in the female body, the correct answer would be humans.

### Conclusion
- Therefore, the answer to the question is that in humans, the sperm can survive for a longer period in the body of the female compared to other animals.
