Boric Acid and Sperm Cells: Can You Use Boric Acid To Kill Sperm Cells?

Sperm are essential male reproductive cells and play a crucial role in reproduction as part of semen. Semen is a grayish-white bodily fluid secreted by the male gonads. It contains sperm, also known as spermatozoa, along with fructose and enzymes that support sperm survival for successful fertilization.

On average, a male produces around 73 million sperm cells per milliliter of ejaculate. Once released, sperm can survive in the female vagina for up to 5 days.

Once semen dries on a dry surface like clothing or bedding, sperm are no longer viable. In water, such as a warm bath or hot tub, sperm may survive longer due to the warm and wet environment. However, the chances of sperm from a tub of water causing pregnancy are extremely low, as it is highly unlikely for sperm to find their way inside a woman’s body under such circumstances.

What exactly is boric acid?

Boric acid is a water-soluble compound composed of oxygen, boron, and hydrogen. It appears as a white substance in powder or crystal form and is believed to possess antifungal and antibacterial properties, as per research findings.

The history of boric acid usage dates back to 1873 when it was first employed as a topical antiseptic by Lister. Since then, it has found various applications in eye washes, mouthwashes, skin powders, and ointments. Additionally, boric acid has been used as an irrigant for body cavities, including the pleural space, vagina, and rectum.

For specific skin conditions such as diaper rash, insect bites, athlete’s foot, foot odor, and yeast infections, diluted boric acid has been utilized as a treatment. In this article, we will explore how boric acid interacts with sperm cells.

Does Boric Acid Kill Sperm cells?

No, research has shown that while boric acid can have a negative impact on sperm cells and their quality when exposed acutely, these effects are reversible.

Using boric acid as a contraceptive is not recommended, as it does not prevent pregnancy and may even harm an unborn child and impair fertility in some women.

Moreover, combining boric acid with other forms of contraception like condoms or diaphragms can damage the barrier and reduce their effectiveness.

For effective contraception, the use of spermicides is a safer option. Spermicides contain chemicals that slow down sperm, preventing them from reaching an egg. They come in various forms, such as creams, gels, films, foams, and suppositories, and can be purchased over-the-counter without a prescription.

It’s important to be aware that using boric acid alongside vaginal spermicides can decrease their effectiveness and interfere with their proper functioning. Therefore, it’s best to use spermicides alone for reliable contraception.

Common side effects of Boric acid include:

  1. Watery vaginal discharge
  2. Mild burning sensation after inserting a capsule
  3. Vaginal discomfort
  4. Hives

Some of the more severe side effects of Boric Acid are:

  1. Vaginal bleeding
  2. Blood vessel disorder
  3. Fever

Before using this medicine, consult your doctor if you have any of the following issues:

  1. Pelvic inflammatory disease
  2. Heart disease
  3. Vaginal bleeding
  4. Poor immune system
  5. High blood pressure
  6. Pain or tenderness in the pelvis or lower stomach
  7. Fever or nausea
  8. Blood vessel disorder

Furthermore, inform your doctor about any allergies or other medications, whether prescription, non-prescription, or herbal, that you are taking before using this medicine.

Can boric acid stop you from getting pregnant?

Boric acid is not a reliable or recommended method of contraception. While some studies have shown that boric acid can have negative effects on sperm cells, it is not a proven or approved contraceptive method. Using boric acid as a means of birth control is not effective and may even be harmful.

For safe and effective contraception, it is essential to use medically approved methods such as condoms, birth control pills, intrauterine devices (IUDs), or other forms of contraceptives.

Can I use boric acid while trying to conceive?

Using boric acid while trying to conceive is not recommended. Boric acid has been shown to have adverse effects on sperm cells and fertility. It may interfere with the ability of sperm to reach and fertilize an egg, which could potentially hinder conception.

If you are trying to conceive, it is essential to avoid using any substances or medications that may negatively impact fertility.
