Spermatozoa are produced in the ................... of testes while the ova are formed in the ................. of the ovaries.

Explanation

**Step-by-Step Solution:**

1. **Identify the Production Sites**: The question asks where spermatozoa and ova are produced. We need to identify the specific structures in the male and female reproductive systems responsible for their production.

2. **Sperm Production**: Spermatozoa (sperms) are produced through a process called spermatogenesis. This process occurs in the **seminiferous tubules** of the testes. The seminiferous tubules are coiled structures within the testes where spermatogonia (sperm precursor cells) undergo division and maturation to form sperm.

3. **Ova Production**: Ova (eggs) are produced through a process called oogenesis. This process occurs in the **ovaries**. Within the ovaries, the primary structures involved in the formation of ova are the **Graafian follicles** (also known as mature follicles). These follicles contain the developing ova and are crucial for ovulation.
