Various changes in mammalian sperm which prepare it to fertilize the ovum are called:
(a) Capacitation
(b) Regeneration
(c) Growth
(d) None of these

Options

A. Capacitation
B. Regeneration
C. Growth
D. None of these

Answer

To solve the question regarding the changes in mammalian sperm that prepare it to fertilize the ovum, we can follow these steps:

### Step 1: Understand the Question
The question asks for the term that describes the various changes that mammalian sperm undergo to become capable of fertilizing the ovum.

### Step 2: Analyze the Options
- **(a) Capacitation**: This term refers to the physiological changes that sperm undergo in the female reproductive tract, which are necessary for fertilization.
- **(b) Regeneration**: This term generally refers to the process of renewal or regrowth of tissues or organs, which is not relevant to sperm maturation.
- **(c) Growth**: This term refers to the increase in size or mass of an organism or cell, which does not specifically relate to the changes in sperm for fertilization.
- **(d) None of these**: This option suggests that none of the provided terms are correct.

### Step 3: Identify the Correct Answer
From the analysis, **(a) Capacitation** is the correct answer. Capacitation is a specific process that sperm must undergo to gain the ability to fertilize an ovum.

### Step 4: Conclusion
Thus, the correct answer to the question is **(a) Capacitation**.
