STIs

STIs stands for sexually transmitted diseases.

During sexual intercourse, you can transmit bacteria, fungi or viruses that cause diseases.

You can become infected during oral sex or other contact

with the vagina, penis or anus.

Most STIs are caused by bacteria or viruses that enter the body

They are transmitted through:

- semen

- Fluids from the vagina

- blood

- contact between mucous membranes.

These mucous membranes are on your penis, anus, vagina and mouth, making sexual contact most likely to cause an STI

STI or STD

There is only one protection against

most STDs during intercourse: 

the condom.

Chlamydia

Chlamydia

Chlamydia is an STI ->

Bacteria in the mucous membranes.

This STI is easy to treat.

If you don't get it treated, it can lead to infertility.

You can transmit this STD during unsafe sex.

HPV

HPV is a virus that is transmitted through sexual contact and can cause cervical cancer.

Vaccination against HPV reduces the risk of developing cervical cancer, anal cancer and throat cancer.

Boys are also vaccinated against

HPV.

 AIDS?

Aids is a disease caused by the aids virus (hiv). As soon as you are infected, you are seropositive. It takes a while before you experience symptoms.

If you are seropositive, you can receive

HIV inhibitors. You will not be cured,

but you will not develop symptoms.

STIs

You CANNOT get an STI from a dirty

toilet 

or by drinking from someone else's glass.

The only way to protect yourself from

STIs is to use a condom.

What should you do if you have an STI?

You often only notice late that you have an STI.

Suffering from symptoms? --> get an STD test done by the doctor.

Herpes and HIV cannot be cured, you remain a carrier.

STI Test

An STD test is used to check whether you have an STI. If you are under 25, you can have an STI test done for free. This can be done at your GP or at the GGD.

Tens of thousands of young people have such a test done every year.

Depending on the type of unsafe sex, different types of tests are done; urine test (men), smear (women), throat or anus swab. Sometimes a blood test is necessary.

Contraception

Unreliable methods:

Periodic abstinence

Coitus interruptus

• Birth control
• Contraceptives = contraceptives Anti = against Conception = fertilization

Unreliable Methods: 

Periodic Abstinence

In this method, the man and woman do not have intercourse around the fertile period.

This method is unreliable,

because you can never determine exactly

when ovulation (ovulation) takes place.

Unreliable methods: 

periodic abstinence:

Ways to determine when ovulation occurs:

Keep a calendar if you have a regular menstrual cycle, so that you can calculate the day of ovulation.

Take your temperature; after ovulation, body temperature is on average 0.3 degrees Celsius higher until the next menstruation.

Vaginal discharge; in many women, discharge becomes more transparent and elastic after ovulation. There is often more discharge.

Unreliable methods: 

coitus interruptus

In this, the man withdraws his penis from the vagina when he feels his organism approaching. Ejaculation then takes place outside the vagina.

This method is unreliable,

because pre-cum can also contain sperm cells.

The pill

The hormones ensure that no egg will mature and be released.

They also ensure that the mucus in the cervix is ​​more difficult for sperm to pass through.

The pill must be taken daily for 3 weeks, followed by 1 week off implantation possible.
