Question

Reference Interval for Sperm characteristics in semen associated with fertility are:
(A) 14% or more have normal morphology
(B) 75% or more are alive
(C) 10×10⁶ sperm per mL
(D) 50% or more with moderate to rapid linear (forward) progression
Choose the correct answer from the options given below:

• A. (A), (B) and (D) only.
• B. (A), (B) and (C) only.
• C. (A), (B), (C) and (D).
• D. (B), (C) and (D) only.

Hint:

Sperm viability, morphology, and motility are crucial parameters in determining male fertility. Reference intervals help assess reproductive health.

Answer 1

The Correct Option is A

• 14% or more have normal morphology: This indicates a healthy sperm morphology, critical for fertility.
• 75% or more are alive: High viability ensures functional sperm capable of fertilization.
• 50% or more with moderate to rapid linear progression: Forward motility is essential for reaching and fertilizing the egg.
• Option (C): is not included as the standard threshold for sperm concentration is higher than \(10 \times 10^6\) sperm/mL.
