Final answer:
The direct answer to the student's question is b. vasovasotomy, vasectomy, which involves the reversal of a vasectomy—a surgical sterilization procedure preventing sperm from being ejaculated due to the sealing of the vas deferens.
Step-by-step explanation:
A vasectomy is a surgical sterilization procedure in males in which the vas deferens are blocked so sperm cannot be ejaculated. A reversal of a vasectomy, which is designed to restore fertility, is known as a vasovasostomy. Therefore, the correct answer to the student's question is b. vasovasotomy, vasectomy. During a vasectomy, the vas deferens from each testis is clamped, cut, or otherwise sealed to prevent sperm from traveling from the epididymis.
If sperm do not exit through the vas deferens due to a vasectomy, they remain in the epididymis and are eventually reabsorbed by the body. A vasovasostomy is the surgical procedure that attempts to reconnect the vas deferens and enable the possibility of sperm ejaculation once again.
