How do STDs affect fertility in women?

Sexually Transmitted Diseases (STDs) or Sexually Transmitted Infections (STIs) can cause a wide range of health complications, one of which is infertility.

When treated correctly, not all STDs or STIs will cause infertility and it really is dependent on the woman’s body, how soon it was treated, and what the disease itself was.

According to the American Social Health Association, as many as 15 percents of the women who are infertile due to an STD [1].

The reason for infertility is a pelvic inflammatory disease (PID) which is generally preventable (when linked with a previous STD) and causes scarring on the fallopian tubes and pelvic organs[2].

This is especially true of STDs, which have no symptoms (and a few do). Which is why protecting yourself is important because you might not know you actually have an STD/STI because there are no symptoms and the longer it goes untreated, the more likely it is to affect your fertility.

In order to protect your health and your ability to conceive in the future, it’s important to protect yourself. If you don’t know your partner is free from an infection/disease, then you’ll want to consider using condoms.

Below you’ll find a review of some of the more commonly known STDs/STIs and how they can affect your fertility as a woman.


Chlamydia is a rather common STD. In fact, among STDs, it is the most important cause of infertility in women. The disease is most common in people aged between 15 and 29 years.

According to the CDC, there are over 2.8 million people diagnosed with chlamydia every year [3].

It is also more prevalent in women than in men. Chlamydia is asymptomatic so it’s easy for one to get the infection and stay for a long time without being diagnosed or treated.

One issue with this, because of its lack of symptoms, woman don’t get tested and it’s also not routine in the screening [4].

If you are with a new partner, or your significant other has other partners as well (because open relationships are a thing), be honest with yourself and each other in order to be sure that you aren’t contracting anything and also request to be tested for it when you go for your yearly screening at least.

Chlamydia in women, if left untreated, can cause pelvic inflammatory disease (PID). PID often causes ectopic pregnancy and tubal infertility.

It’s not only women who might become infertile, but it can also affect men, and if a man does have an infection it could mean the couple is one third less likely to get pregnant [5].

Gonorrhea can cause just as much damage as Chlamydia (and if you do get pregnant, it’s actually the leading cause of blindness in newborns [6]).

There are more than 800,000 people who are diagnosed with gonorrhea yearly in the United States alone [7].

This makes it the second most common STI/STD in the US [8]. Like Chlamydia, it also can go undetected as well and can also cause damage to the health of male sperm as well.

Because it’s the second most common disease, it’s also the second most preventable cause of infertility [9].

Trichomoniasis, also popular as trich, is an infection caused by a tiny, one-cell parasite and spread through sexual contact.

It affects both men and women but is more common in women where the parasite usually infects the vagina, urethra, cervix, and bladder.

Many times the disease will come without symptoms. However, where the symptoms develop, they usually appear within about a week after infection.

Symptoms in women include a change in vaginal discharge; you will notice an abnormal color or odor. Vaginal itching is also common as well as pain during sex.

The reason this can cause infertility is due to the potential fallopian tube inflammation which can affect the ability to conceive [10].

There are a few other STDs such as Mycoplasma genitalia and Syphilis, which were not discussed here that can affect the fertility of a woman.

In general, if you are seeing someone new, in an open relationship (either you or your partner) whatever the case may be, protect yourself. There is only one way to protect against and STI/STD and that is condoms.

So, no, we aren’t saying to stay away because sex is a natural part of life, just be safe while having fun. If you do believe you have an infection, talk to your doctor and get tested, and you can also ask for testing at your yearly if necessary as well.
