Birth Control Method
A woman gets pregnant
when man's sperm fertilizes the ovum (the eggs) in the uterus. When man ejaculates
into vagina, millions of tiny sperm are released. However, studies have shown
that upto 99% of them die due to unfriendly environment inside the vagina. It
is also found that liquid or chemical of the vaginal is natural barrier and kills
many sperms at the doorstep itself. Only 1% of the total quantity of sperm could
pass through vagina to uterus to fertilize the egg, resulting in pregnancy. But
it should be noted that only sperm could be powerful enough to fertilize the egg
and occur pregnancy.
Spermicides are barrier birth control methods that
mean you don't need to consume pills. It comes in the form of jellies, film, creams,
foams and suppositories. It is inserted the vagina prior to having intercourse
to kill the sperm, stopping viable sperm to reach to uterus.
Spermicides are placed into vagina, preferably 5-15 minutes prior of
having intercourse. This much time is required for spermicides to melt, liquefy
with the wet vagina or its natural chemical. It should be inserted properly to
get desired results. Once inserted, it starts melting into a liquid form that
build the coating wall around the vagina. It works as the barrier for sperm to
pass through vagina and cervix so that sperm should not swim into it to reach
uterus and fertilize the eggs.
Which is the best spemicides for preventing
Among all the spermicides available, a foam or detergent like spermicide
(for example, Nonoxynol-9) is very much effective. It melts and releases the foam
that makes the coating wall across the vagina thus prevent sperm to pass through
to reach uterus. Some of them are available in solid or semi-solid form.
to use spermicide effectively?
Effectiveness of spermicides is very much depending
upon how and when you use it. As said earlier, it should be generally inserted
15 minutes prior to having intercourse. Spermicides come into various forms so
the different usages are. Liquid form of spermicides like creams, jellies and
foam must be placed deep into vagina, near to the cervix. Other suppositories
should be inserted into vagina unwrapped but not in the rectum.
how you follow the instruction on the packet of spermicides are also important
factors influencing the effectiveness.
- Woman preferably must apply spermicides,
and if she is using the film form then she must insert it with her finger rather
than instructing man to do with his erect penis.
- It is common belief that
spermicides should be applied when your partner is ready to put his penis into
vagina. In fact, spermicides must be applied atleast 15 minutes prior to having
intercourse. If intercourse going to be delayed for more than 15 minutes, more
spermicides should be applied.
- Do not put liquid, specially water into vagina
to wash it for atleast 8 hours after the intercourse. - All instruction must be
followed properly to get maximum protection.
Effectiveness of spermicides
is 70 to 90%, which is very much depending upon the type of spermicide you use,
timing, quantity you use and how you followed the instruction.

be noted that spermicides do not protect against STDs or HIV.
