Which of the following is not a part of female reproductive system ?
Ovary, oviduct uterus, vasdeferens, hymen

Answer

To determine which of the following is not a part of the female reproductive system, we need to analyze each option provided:

1. **Ovary**: The ovaries are the primary sex organs in females. They produce eggs (ova) and hormones such as estrogen and progesterone. Therefore, ovaries are a part of the female reproductive system.

2. **Oviduct (Fallopian tube)**: The oviducts, also known as fallopian tubes, are the ducts that transport the eggs from the ovaries to the uterus. They are considered secondary sex organs in the female reproductive system.

3. **Uterus**: The uterus is a hollow organ where a fertilized egg implants and develops into a fetus. It is a crucial part of the female reproductive system.

4. **Vas deferens**: The vas deferens is a duct in the male reproductive system that transports sperm from the epididymis to the ejaculatory duct. It is not part of the female reproductive system.

5. **Hymen**: The hymen is a membranous structure that partially covers the vaginal opening in females. It is considered part of the external genitalia and thus part of the female reproductive system.

After analyzing all the options, we conclude that the **vas deferens** is not a part of the female reproductive system.

**Final Answer**: Vas deferens
