Which of the following is not true regarding artificial insemination?

Options

A. Ideal parents are carefully chosen before the female is impregnated.
B. The semen may be used immediately or can be frozen and used at a later date
C. The fertilised eggs at 8-32 cells stages, are recovered from the original parent non-surgically and transferred to surrogate mothers.
D. It helps in overcoming several problem of normal matings.

Answer

To solve the question "Which of the following is not true regarding artificial insemination?", we will analyze each option provided and determine which statement is incorrect.

### Step-by-Step Solution:

1. **Understanding Artificial Insemination**:
- Artificial insemination (AI) is a reproductive technology used to introduce sperm into a female's reproductive tract without natural mating. It is often used in animal breeding and human fertility treatments.

2. **Evaluating the Options**:
- **Option 1**: "Idle parents are carefully chosen before the female is impregnated."
- This statement is true. In artificial insemination, careful selection of the male and female parents is crucial to ensure desired traits in the offspring.

- **Option 2**: "The semen may be used immediately and can be frozen and used at a later date."
- This statement is also true. Semen can be used right after collection or can be preserved by freezing for future use.

- **Option 3**: "The fertilized egg at the 8 to 32 cell stages are recovered from the original parent non-surgically and transferred to the surrogate mother."
- This statement is misleading. While embryos can be transferred to surrogate mothers, the process described is more aligned with embryo transfer techniques rather than artificial insemination itself. AI typically involves the introduction of sperm, not the transfer of fertilized eggs.

- **Option 4**: "It helps in overcoming several problems of normal mating."
- This statement is true. Artificial insemination can help address issues such as infertility, timing of mating, and genetic diversity.

3. **Conclusion**:
- The statement that is not true regarding artificial insemination is **Option 3**.

### Final Answer:
**Option 3** is not true regarding artificial insemination.
