Current Question (ID: 15734)

Question:

Match the Column-A with the Column-B: Column-I I. IUT II. Birth control III. Spermicides IV. STD Column-II A. Copper T B. Agent to kill spermatozoa C. VDRL D. To help infertile couple

Options:

1. I → D, II → C, III → A, IV → B
2. I → D, II → C, III → B, IV → A
3. I → B, II → D, III → A, IV → C
4. I → D, II → A, III → B, IV → C

Solution:

I. IUT: is a technique to help infertile people, the semen collected either from the husband or a healthy donor is artificially introduced either into the vagina or into the uterus of the female. II. Birth control: Copper T is an IUD which increases phagocytosis of sperms within the uterus and the Cu ions released suppress sperm motility and the fertilising capacity of sperms. III. Spermicides: agent to kill spermatozoa, are used along with condoms and other barriers to increase contraceptive efficiency. IV. STD: VDRL stands for Venereal Disease Research Laboratory, is a blood test that detects an antibody that is present in the bloodstream when a patient has syphilis.
