What is the principal purpose of adding an extender to diluted semen used for artificial insemination?
Correct answer: D. To preserve sperm viability during storage and transport
- A. To initiate ovulation in the female
- B. To increase the genetic age of spermatozoa
- C. To destroy all seminal plasma proteins
- D. To preserve sperm viability during storage and transport
Explanation
Semen extenders provide nutrients, buffering capacity and protection against temperature and osmotic injury, thereby maintaining sperm viability during storage and transport. They do not induce ovulation or alter the genetic age of sperm cells.
