Surgical Contraception Methods — NEET Biology
📚 Practice ConceptSurgical methods of contraception prevent gamete formation.
Which of the following statements concerning surgical contraceptive methods are NOT correct? S1: Vasectomy is a sterilisation procedure performed in males by tying or removing a small part of the vas deferens. S2: Tubectomy involves the removal or tying of a small part of the fallopian tube, performed in females. S3: Both vasectomy and tubectomy are highly effective methods, but their reversibility is very poor. S4: Surgical methods of contraception primarily prevent gamete formation in both males and females. S5: These methods are generally advised as terminal methods for couples who do not wish for any more pregnancies.
View solution & NCERT explanation
Correct answer: B — S4 only
Let's evaluate each statement: S1: In vasectomy, a small part of the vas deferens is removed or tied up through a small incision on the scrotum (Figure 3.4a). This statement is correct. S2: In tubectomy, a small part of the fallopian tube is removed or tied up through a small incision in the abdomen or through vagina. This statement is correct. S3: These techniques are highly effective but their reversibility is very poor. This statement is correct. S4: Surgical intervention blocks gamete transport and thereby prevent conception, not gamete formation. This statement is NOT correct. S5: Surgical methods, also called sterilisation, are generally advised for the male/female partner as a terminal method to prevent any more pregnancies. This statement is correct. Only statement S4 is NOT correct.
