A suppository, when inserted in the vagina a few minutes
prior to intercourse, is melted by body heat. The melted greasy base coats the
opening of the uterus and forms a barrier to sperm while the chemical kills the
sperm. Although sound in principle, the suppository has not been found to be
completely reliable. Sometimes it does not melt properly prior to ejaculation
or when melted does not completely cover the mouth of the womb.
Jellies and
creams work on the same principle as suppositories. Inserted into the vagina
with a special applicator, they are intended to block the opening into the
uterus and destroy sperm. Since they are already in semi fluid form, they have
an advantage over the suppository in not having to melt before the crucial
moment. Tests on some jellies and creams have been promising. Your doctor will
know if physicians conclusively demonstrate in the future that these methods
are reliable.
Coitus interrupts
consists of withdrawing the penis from the vagina just prior to ejaculation.
One of the oldest methods of birth control, mentioned in the Bible in the story
of Oman who "spilled his seed upon the ground," it is still widely
practiced. We do not recommend it for several reasons. Even if successfully
practiced, it is not an adequate safeguard since sperm may leak out before
actual ejaculation. It can cause tension and strain, placing heavy
responsibility upon the man, who finds it no easy matter to exercise control
while highly excited. He may become irritable, emotionally disturbed, and have
guilt feelings if he fails. The wife's concern lest he should fail to withdraw
at the proper moment is a source of fear, tension, and emotional difficulties
for her as well.
Coitus interrupts does not permit development of the full
love and tenderness that come when intercourse is completed with sexual organs
united. The contraceptive techniques we have described here are the most
common, but others exist. Every couple must decide which, if any, to use-and
should discuss the subject with their doctor or a qualified person at a birth
control clinic or family planning agency. Most large cities and many smaller
ones have such services. Or you may write to Planned Parenthood-World
