Options

A. Vasectomy
B. Ductus arteriosus
C. Orchidectomy
D. Tubectomy

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the procedure of tying up or removing a small part of the fallopian duct (also known as the fallopian tube or oviduct).

2. **Identifying the Structure**: The fallopian tube is a paired structure in females that plays a crucial role in the reproductive system. It consists of several parts: the fimbriae, infundibulum, ampulla, and isthmus.

3. **Explaining the Procedure**: When a small part of the fallopian tube is cut and tied, it prevents the passage of gametes (eggs) from the ovary to the uterus. This blockage inhibits fertilization since sperm cannot reach the egg.

4. **Naming the Procedure**: The procedure of cutting and tying the fallopian tube is known as "tubectomy." This is a permanent method of contraception as it prevents any future pregnancies.

5. **Differentiating from Other Procedures**: It is important to distinguish tubectomy from other surgical procedures related to reproduction, such as vasectomy (which is a male sterilization procedure) or orchiotomy (removal of the testis).

6. **Conclusion**: Therefore, the correct answer to the question is that tying up or removing a small part of the fallopian duct is called "tubectomy."
