Question

Why the coitus interruptus method shows very high failure rate
A. Coitus interruptus is not possible
B. Initial secretion in male, may also contain sperms
C. Capacitation occurs in Vagina
D. None of the above

Answer 1

The oldest method of family planning, coitus interruptus or withdrawal, is still extensively used today. Before ejaculation, the male withdraws his penis, avoiding semen from accumulating in the vaginal canal. It is appropriate for women who have infrequent intercourse or who are awaiting the start of another type of contraception. Coitus interruptus has the advantage of being able to be utilised by persons who oppose or do not have access to other kinds of contraception.

Complete answer:
Option A: Coitus interruptus, also known as withdrawal or the pull-out method, is a contraception method in which the penis is removed from the vagina before ejaculation during sexual intercourse, largely to avoid transferring semen into the vagina.
So, option A is incorrect.
Option B: The male's pre-coital secretions may contain enough sperm to result in conception.
So, option B is correct.
Option C: Sperm capacitation is a natural process that occurs after sperm has been ejaculated and is required for ovum fertilisation.
When ejaculated semen comes into contact with the female vaginal tract, something happens.
So, option C is incorrect.
Option D: Self-discipline is required while using the withdrawal method for birth control.
Even yet, the withdrawal approach isn't a particularly effective birth control approach.
If the withdrawal isn't timed correctly or if the pre-ejaculation fluid contains sperm, sperm may enter the vagina.
So, option D is incorrect.

Hence, Option B is the correct answer.

Note:
Coitus interruptus is less successful at preventing pregnancy than other reversible means of contraception such as IUDs, hormonal contraceptives, and male condoms.
As a result, it is less cost-effective than many more effective methods: despite the fact that the approach has no direct cost, users are more likely to face the risks and expenses of childbirth or abortion. In the prevention of sexually transmitted infections, such as HIV, the approach is usually ineffective. Since pre-ejaculate may include virus or bacterial particles that could infect the partner if it comes into touch with mucosal membranes
