Question

Which of the following is correct about the capacitation process occuring prior to fertilisation?

• A. Process by which sperm are released from the penis into the vagina of a female
• B. Removal of plasma membrane present over acrosome
• C. Capacity of the egg to get fertilised
• D. Capacity of testes to hold the sperms

Answer 1

The correct option is B Removal of plasma membrane present over acrosome

The release of sperm from the penis into the vagina of a female is called insemination.
Once sperms are released, the capacitation of sperm occurs in the female reproductive tract. During capacitation, the medium inside the uterus wears off the coating substances of the sperm head. This exposes the receptor sites on the acrosome of sperm making it penetrate the egg. Capacitation involves the processes that cause sperm activation.
