When a female oviduct is blocked, which method of external fertilization would be used?

A. Artificial Insemination
B. In vitro Fertilization
C. Natural Fertilization
D. Cloning

Answer :

Final answer:

When a female oviduct is blocked, In vitro Fertilization (IVF) is the appropriate method for fertilization. IVF allows for the fertilization of eggs outside the body and implantation directly into the uterus. Other methods like artificial insemination or natural fertilization would not be effective in this scenario.


Explanation:

Understanding Fertilization Methods

When a female oviduct is blocked, it typically prevents sperm from reaching the egg in a natural setting, leading to complications with fertilization. In cases where natural fertilization becomes impossible, assisted reproductive technologies may be utilized to achieve pregnancy. Among the options given, In vitro Fertilization (IVF) is the most appropriate method for fertilization in such situations.

Why Choose In Vitro Fertilization?

IVF involves collecting eggs from the ovaries and fertilizing them with sperm outside the body, in a laboratory setting. This eliminates the need for a functional oviduct since the fertilized egg can be implanted directly into the uterus. This method is beneficial for women with blocked oviducts, as it offers an alternative route to conception without the constraints of natural fertilization.

  1. Artificial Insemination would typically require functional oviducts to be effective.
  2. Natural Fertilization is not possible with blocked oviducts.
  3. Cloning does not relate directly to fertilization and is not a method used for achieving pregnancy in cases of blocked oviducts.

In summary, when faced with the challenge of blocked oviducts, IVF stands out as the viable solution for achieving fertilization and conception.
