Final answer:
The plastic repair of an oviduct is called salpingoplasty, a surgical procedure that can correct obstructions in the fallopian tubes and improve a couple's chances of conceiving naturally. The correct option is c.
Step-by-step explanation:
The term for the plastic repair of an oviduct is salpingoplasty. This procedure may be recommended if a couple has been trying to conceive and the endocrinologist diagnoses an obstruction in the female's oviducts.
During a salpingoplasty, any obstructions in the fallopian tubes are surgically removed, and the integrity of the tubes is restored, possibly enhancing fertility by allowing for internal fertilization. Sterilization in females, on the other hand, involves a procedure called tubal ligation, where the fallopian tubes are severed and sealed, which prevents sperm from reaching the ovum.
For a couple trying to conceive, the fertilization process typically involves the internal union of sperm and egg within the oviduct. If blockages prevent this natural process, salpingoplasty can restore the pathway for the sperm to meet the ovum. In more complex cases, assisted reproductive techniques such as in vitro fertilization might be considered.
Therefore, the correct option is c.
