Spontaneous protection is provided by substances that are only used during or shortly before sexual intercourse. They do not interfere in the hormonal balance. Their reliability depends on the respective substance and their correct use.
Chemical contraceptives
Foam ovule Patentex
oval
 The
hormone-free ovule is inserted into the vagina
where it dissolves into a microfine foam. By this
means the spermicidal active ingredient, nonoxinol-9,
is ideally distributed to make sperm immobile.
Thus Patentex oval guards reliably against pregnancy
without interfering with the hormonal balance.
 The
foam ovule acts for up to two hours and is well
tolerated. Furthermore, the active ingredient
nonoxinol-9 also inactivates bacteria, fungi and
parasites. Patentex oval is available from pharmacies
without prescription
.
Vaginal tablets or
suppositories
These are inserted into
the vagina. After a 10-minute waiting period they
dissolve and the spermicidal active constituent
guards against sperm penetration. The distribution
may not be as even as with foam or a spray.
Sprays and gels
The active ingredient
is already contained in the base substance, and
is introduced into the vagina through a dosing
tube. The active ingredient inactivates the sperm.
Important:
These methods have to be repeated each time you
have sexual intercourse.
Chemical contraceptives
can be bought from pharmacies without a prescription.
Physical contraceptive
methods
 Condoms
Condoms are the most common form of contraception
that can be used by men. A condom is an ultra-thin
tube of rubber with one end sealed off. It is
put onto the erect penis and stops sperm before
they can enter the female vagina. Condoms must
always be put onto the penis before (!) sexual
intercourse, not shortly before ejaculation. A
new condom must be used each time you have sexual
intercourse. Condoms are sensitive to light and
temperature, must be stored where they cannot
be damaged, and must not be used after the expiry
date. They also offer protection against AIDS
and other sexually transmitted diseases.
Condoms are available from pharmacies without
a prescription.
Diaphragm,
Dutch cap,
lea contraceptivum (female condom)
In these barrier methods the opening of the womb
is covered with "caps" of variable sizes
made of rubber, latex or silicone. Additional
spermicidal gel or cream applied to the inner
surface increases protection. The cap only seals
off the opening of the womb, while diaphragms
and female condoms cover the whole of the top
end of the vagina. Caps and diaphragms are made
out of rubber and are available in various sizes.They
must be fitted individually at the doctor's practice
or a health advice center. The female condom is
available in one universal size and adapts its
size individually. It is available from pharmacies
without a prescription.
