Testes are primary sex organs of male while ovaries and breasts are primary sex organs of female.

Answer

**Step-by-Step Solution:**

1. **Understanding Primary Sex Organs:**
- Primary sex organs are those organs that are directly involved in the reproduction process. In males, the primary sex organ is the testes, while in females, the primary sex organs are the ovaries.

2. **Role of Testes:**
- The testes are responsible for producing sperm and secreting male hormones, primarily testosterone. Testosterone plays a crucial role in the development of male reproductive tissues and the regulation of various functions related to reproduction.

3. **Role of Ovaries:**
- Ovaries are the primary sex organs in females. They produce ova (eggs) and secrete female hormones such as estrogen and progesterone. These hormones are essential for regulating the menstrual cycle and supporting pregnancy.

4. **Breasts as Secondary Sex Organs:**
- Breasts are not considered primary sex organs. They are classified as secondary sex organs because their primary function is related to lactation (milk production) after childbirth, rather than direct involvement in reproduction. They develop under the influence of female hormones but do not participate in the fertilization process.

5. **Conclusion:**
- The statement in the question is incorrect because it categorizes breasts as primary sex organs in females. Breasts are accessory organs, while the primary sex organs are the ovaries.

**Final Answer:**
The statement is false because, while testes are the primary sex organs of males and ovaries are the primary sex organs of females, breasts are classified as secondary sex organs, not primary.
