2. **Understand the Function of Leydig Cells:**
- The primary function of Leydig cells is to produce hormones, specifically androgens. The most important androgen produced by Leydig cells is testosterone.

3. **Describe the Secretion of Leydig Cells:**
- Leydig cells secrete testosterone, which plays a crucial role in the development and maturation of male reproductive organs and secondary sexual characteristics. This includes the functioning of male accessory sex organs such as the epididymis, vas deferens, seminal vesicles, prostate gland, and urethra.

4. **Summarize the Key Points:**
- In summary, Leydig cells are located in the interstitial spaces of the testes and secrete testosterone, which is vital for male reproductive health.
