A sperm reaches the female reproductive tract but cannot yet fertilise the oocyte. Which process normally enables the sperm to acquire fertilising ability?
Correct answer: B. Capacitation
- A. Implantation
- B. Capacitation
- C. Menstruation
- D. Cleavage
Explanation
Capacitation is a functional maturation process that occurs in the female reproductive tract and prepares sperm for the acrosome reaction. Implantation involves the early embryo, menstruation is endometrial shedding, and cleavage refers to early divisions of the zygote.

About Reproductive Anatomy and Conception
Female and male reproductive organs, pelvic anatomy, gametogenesis, the menstrual cycle and the hormonal control of ovulation lead into fertilisation, implantation and early embryonic development. Questions distinguish ovulation from menstruation, fertilisation from implantation, and the normal anatomical changes that allow conception and pregnancy to occur.
