• B. stimulate the couple for longer sexual intercourse
• C. supplement their contraceptive efficiency
• D. suppress the release of LH and FSH

Answer 1

The correct option is C supplement their contraceptive efficiency

There are several methods of birth control that are used for the prevention of pregnancy and sexually transmitted diseases (STDs).
Natural methods, where there is no use of any mechanical or chemical contraceptive substances. In barrier methods of birth control, ovum and sperms are prevented from physically meeting up with each other.
There are mainly three type of barrier methods used by females: These are made of rubber, which is inserted inside the female reproductive tract to cover the entrance of the uterus, thereby preventing the sperms from entering the cervix. Spermicides are contraceptive substances that come in different forms like creams, jellies, foams and vaginal tablets called pessaries, which kills/destroys sperms. Using spermicides along with these barriers make it more efficient and effective in contraception. It kills most of the sperms that enter the vagina, the remaining sperms are stopped by the barrier at the mouth of the cervix and that is how fertilisation is averted. Basically, spermicidal creams, jellies, foams and vaginal tablets are usually used along the barrier methods of contraception to increase their contraceptive efficiency.
Spermicides do not specifically affect or enhance the duration of the intercourse, neither do they stimulate the pituitary to release or suppress LH and FSH hormone secretion.
