Which one of the following statements is FALSE in respect of viability of mammalian sperm?

  1. A
    Sperms must be concentrated in a thick suspension
  2. B
    Sperm is viable for only up to 24 hours
  3. C
    Survival of sperm depends on the pH of the medium and is more active in alkaline medium
  4. D
    Viability of sperm is determined by its motility

Solution & Step-by-step Explanation

Mammalian sperms remain viable in the female reproductive tract for about 48 to 72 hours. Saying it is viable for "only up to 24 hours" is incorrect. All other statements regarding concentration, alkaline pH requirement, and motility as a sign of viability are correct.
