Does Boric Acid Kill Sperm? What Science Says About Its Effects on Fertility

Boric acid is the best remedy for treating yeast infections and controlling household pests. But can it also impact fertility? Surprisingly, the common question that arises is "Does boric acid kill sperm?" Whether out of concern or curiosity, this question is worth answering. Let's explore the blog and learn about the unexpected effect of boric acid on sperm health. But first, have a basic understanding of boric acid. 

What is Boric Acid?

Boric acid is a potent chemical consisting of boron, oxygen, and hydrogen. It has antimicrobial and antifungal effects and has been considered for domestic and industrial uses. This chemical is used to prepare medicines such as boric acid suppositories to treat bacterial vaginosis and vaginal yeast infection. It is also used as a pesticide for flies, rats, ants, and cockroaches, and to clean off fungi and algae in the swimming pool water. Moreover, it serves as a potent cleaning agent and is used in many products. However, use it cautiously, as it can be harmful.

Does Boric Acid Kill Sperm?

Yes, it can due to its spermicidal properties, which can kill or inactivate sperm cells. According to the United States Environmental Protection Agency, acute contact with boric acid can harm the process of sperm release and the quality of sperm. This chemical can harm sperm by affecting their movement and ability to survive. But this study is based on animals and typically involves oral use, not vaginal use.

When used vaginally as a boric acid suppository, it can lower the pH level of the vagina, which creates an environment that is not favorable for fungal growth. The low pH balance can reduce sperm movement and survival for a temporary period. Still, boric acid is not recommended or safe to use as a reliable contraception to prevent pregnancy. 

How Does Boric Acid Impact Sperm Cells?

Boric acid produces a toxic effect on sperm cells. When these cells come in contact with boric acid (particularly in huge amounts), this chemical can:

• interrupt the permeability (absorptive properties) of the sperm cell membrane

• affects the mobility (movement) of sperm cells, making them less able to reach the egg and fertilize it.

• cause damage to sperm cells, resulting in cell death.

Due to these effects, the boric acid might kill or impair sperm. 

Important Warnings:

Despite the ability of boric acid to kill sperm, it should not be used as a form of contraceptive to prevent pregnancy. Here are the reasons why:

• Toxicity: Being toxic and harmful, boric acid can be absorbed through the mucous membranes in excess amounts.

• Vaginal Irritation: This chemical can cause irritation or burning in the vagina, or also lead to vaginal flora imbalance if not used correctly.

• Disapproved for Contraception: Boric acid is not tested and approved as a spermicide. So, choose other effective and safer birth control methods.

How Does Boric Acid Impact Sperm's Function?

Several studies show that boric acid is toxic to sperm. Mainly, sperm mobility and viability are poorly targeted by this chemical. However, research has shown adverse effects on the sperm of animals with oral boric acid consumption. Yet, human trials do not confirm the same. The effects of boric acid on human sperm should undergo further experiments. Hence, individuals must skip its usage in contraception for the time being.

What Happens When You Have Sex After Using Boric Acid?

If you and your partner have sex, especially vaginal sex with 24 hours of inserting one suppository in your vagina, there are chances of some side effects or risks due to the left residue, which didn't dissolve properly.

• Your partner's genital skin can be exposed to boric acid during vaginal sex, which can cause irritation, itching, and a burning sensation. 

• It can damage birth control options, like condoms and diaphragms, and also make spermicides present in the vagina less effective.

• Having sexual intercourse, particularly unprotected sex, immediately can reduce the effectiveness of boric acid in treating vaginal infections.

• If accidentally swallowed, avoid oral sex for some days to avoid accidental ingestion.

For the safer side, it is advised to wait for completion of the full course of the boric acid treatment (that is usually 7-14 days) before engaging in sexual intercourse. If your partner develops any symptoms that persist for a longer time, see a doctor. Once the infection is cleared and there are no symptoms, you can engage in sexual activities. But never forget to use condoms during sex to prevent the risk of developing sexually transmitted infections (STIs). 

How Long After Having Boric Acid Can I Have Sexual Intercourse?

Doctors may recommend waiting for at least 12 to 24 hours before having intercourse after they have used a boric acid suppository. Suppository may get enough time to dissolve fully. The area may return to its normal pH levels, preventing unnecessary discomfort to you and your partner. However, take a shower after engaging in sexual activity to remain on the safe side. Making intimate relations with caution is something rational.

Can Boric Acid Help in Birth Control?

No, boric acid is not at all recommended for preventing pregnancy. Although people in the early days used boric acid as a contraceptive, doctors disapprove of its efficacy in birth control. There are many safe contraceptive methods (such as condoms) that one can choose from. After all, infections can also be kept away by using such birth control methods. Discuss with your doctor about any reliable contraceptive means. Make desired changes in your lifestyle and ensure safe sex practices.

Can Boric Acid Cause Miscarriage?

There are several myths associated with miscarriage, but miscarriage with the use of a boric acid suppository is actual. A 2023 study has agreed that this chemical can induce toxicity to a developing fetus. Besides, women may undergo pregnancy loss, and birth disabilities can happen. It is always better to avoid boric acid suppositories during pregnancy. However, if boric acid exposure is low, it can be fine. Still, a pregnant woman or someone willing to conceive must be aware of the side effects of boric acid, which include:

• Burning sensation at the vaginal opening

• Watery discharge

• Redness around the area of the vagina

Boric Acid Safety Guidelines: Precautions to Take

Safe use of boric acid is always advisable for doctors and other researchers.

Let us discover some crucial safety precautions one should not miss out on:

• Use the boric acid suppository for vaginal yeast infection, as directed. Using high doses (around 5-20 g once) can cause vomiting, diarrhea, abdominal pain, and skin irritation.

• Keep the acid away from children and pets to avoid accidental ingestion and harm.

• If you are using this chemical for pest control, follow the instructions properly. Abide by the safety guidelines that are mentioned on the bottle.

• Wash your hands properly after using the boric acid to eliminate the risk of skin irritation or accidental ingestion.

• If your eyes come into contact with boric acid, clean them off thoroughly using cool water for a few minutes.

• When you are using it indoors, make sure there is enough ventilation, like a fan and open windows. 

• Avoid:

1. Swallowing it

2. Using it on open wounds or on kids. 

3. Using during pregnancy without medical guidance  

4. Using it if you have sexually transmitted diseases, pelvic inflammatory disease, or sensitivities in your lower abdominal or pelvic area, without a doctor's advice.

Summing Up 

So, does boric acid kill sperm? Excess use of boric acid may hamper sperm quality and release, which can disrupt fertilization. Use it as directed and seek guidance from experts. Moreover, never use it as birth control or any protection against STDs. Seek a healthcare professional if you suspect anything unusual after using this acid. After all, your health should be your priority every time.
