Answer :
Final answer:
When a female oviduct is blocked, artificial methods like In Vitro Fertilization (IVF) can be used to achieve fertilization. IVF involves fertilizing eggs outside the body and is a suitable alternative when natural fertilization is not possible. Other methods like artificial insemination may also be considered but do not directly address the blockage issue as effectively as IVF.
Explanation:
Understanding Fertilization Options
When a female oviduct is blocked, leading to complications in the natural process of fertilization, external solutions are often considered. Each method of fertilization varies in its approach to overcoming such challenges:
- Artificial Insemination: This method involves the direct introduction of sperm into a female's reproductive system. It is often used when natural fertilization is not possible due to various physical barriers, including blocked oviducts.
- In Vitro Fertilization (IVF): In this procedure, eggs are retrieved from the ovaries and fertilized by sperm outside the body in a laboratory setting. The resultant embryos are then implanted into the female’s uterus, bypassing any blockages in the oviducts.
- Natural Fertilization: This occurs when sperm meets egg within the female reproductive tract. However, in cases of a blocked oviduct, this method is not viable.
- Cloning: Cloning is a method of reproduction that creates a genetically identical organism, but it is not typically used to address fertilization blockages in a natural reproductive context.
Given the context of blockages in the female reproductive tract, In Vitro Fertilization (IVF) is the most relevant method because it specifically circumvents the blockage by allowing fertilization to occur outside the body.
