Question

________ refers to the collective changes that activate the sperm when in contact with the fluids of the female genital tract.

• A. Fertilisation
• B. Spermatogenesis
• C. Capacitation
• D. Ejaculation

Answer 1

The correct option is C Capacitation

Capacitation refers to the collective changes that help the sperm to become active with increased motility so that it can actively swim and reach the ovum successfully. Out of the many changes, a fundamental change that occurs during capacitation is alkalinization of sperm cytoplasm.

Once the sperm reaches the ovum, both the gametes fuse together. This fusion is called fertilisation.

Spermatogenesis refers to the process by which primordial germ cells of male divide repeatedly to ultimately form haploid sperms. It is the proliferation and differentiation of spermatogonia through definite stages of development.

The act of discharge of semen from the male reproductive tract as a result of an orgasm. Orgasm is an intense transient peak sensation of intense pleasure creating an altered state of consciousness associated with reported physical changes.
