Not a function with androgen influence is

Options

A. Libido
B. Catabloism of proteins
C. Spermatogenesis
D. Anabolism of proteins

Answer

To answer the question "Not a function with androgen influence is," we need to analyze the options provided and determine which one does not involve the influence of androgens.

### Step-by-Step Solution:

1. **Understanding Androgens**: Androgens are male sex hormones, with testosterone being the most well-known. They play a significant role in various physiological functions, including sexual development, muscle growth, and protein metabolism.

2. **Analyzing the Options**:
- **Option A: Libido**: Libido refers to sexual desire or drive. Androgens significantly influence libido, especially in males.
- **Option B: Catabolism of Proteins**: This refers to the breakdown of proteins into amino acids. The primary hormones involved in protein catabolism include glucagon, glucocorticoids, and adrenaline. Androgens do not play a significant role in this process.
- **Option C: Spermatogenesis**: This is the process of sperm production in the testes, which is heavily influenced by androgens, particularly testosterone.
- **Option D: Anabolism of Proteins**: This refers to the synthesis of proteins, which is stimulated by androgens, growth hormone (GH), and insulin-like growth factor 1 (IGF1).

3. **Identifying the Correct Answer**:
- From the analysis, we can see that libido, spermatogenesis, and protein anabolism are all functions influenced by androgens. However, catabolism of proteins does not involve androgen influence. Thus, the correct answer is **Option B: Catabolism of Proteins**.

### Final Answer:
**Not a function with androgen influence is: Catabolism of Proteins (Option B)**.
