Can drinking water and salt after intimacy prevent pregnancy?


The concept of using alternative methods to prevent pregnancy has been present throughout history, with various beliefs and practices originating from different cultures. One such belief suggests that consuming a mixture of water and salt after intimacy can act as a natural contraceptive.

According to Healthline, this article aims to explore this myth, examining the scientific basis behind it, while critically analyzing its efficacy and potential risks.

By delving into the biological mechanisms of conception, we can discern if this belief holds any weight or if it is merely based on anecdotal evidence.


Does Drinking Water and Salt After Intimacy Prevent Pregnancy?


Understanding the Conception Process

Before diving into the discussion, it is important to understand the biology surrounding conception.

Pregnancy occurs when sperm fertilizes an egg, resulting in the formation of an embryo.

To achieve this, the sperm must swim through the female reproductive tract, reaching the fallopian tubes, where fertilization typically occurs.

Consequently, any preventive measure must target this journey or interfere with sperm viability or egg development.

Water and Salt as a Postcoital Conception Preventive

The belief in drinking water and salt immediately after intercourse to prevent pregnancy mainly presupposes that these substances can act as spermicides or alter conditions within the reproductive tract to hinder fertilization.

1. Spermicidal Effects:

Water and salt combinations do not possess inherent spermicidal properties.

Spermicides are typically chemicals specifically designed to immobilize or kill sperm cells.

The mere act of drinking water with or without salt cannot directly affect sperm’s viability or motility.

2. Alteration of Vaginal pH:

It is often suggested that drinking a saltwater solution could alter the vaginal pH, making it inhospitable for sperm survival.

However, the vagina maintains its own natural pH level, slightly acidic, which aids in maintaining a healthy environment for beneficial bacteria while inhibiting harmful microorganisms. Consuming saltwater does not substantially change the vaginal pH, and any short-term alterations would unlikely have a significant impact on sperm survival.

3. Disruption of Cervical Mucus:

Cervical mucus plays a crucial role in regulating sperm’s lifespan and motility within the female reproductive tract.

It acts as a protective barrier, blocking or promoting the passage of sperm.

Advocates of the water and salt belief claim that the salt can change the consistency or viscosity of cervical mucus, hindering the sperm’s journey.

However, no scientific evidence supports this assertion, and any possible display of altered mucus would be temporary and unlikely to prevent pregnancy effectively.

4. Interference with Egg Fertilization:

Even if water and salt, by chance, could influence sperm behavior, they would still be ineffective in targeting the egg.

Once the sperm reach the fallopian tubes, fertilization occurs, and the egg is released into the uterus for implantation.

A saltwater solution taken orally would not have any direct impact on this process.

The Risks and Dangers of Using Water and Salt as a Contraceptive

While the belief in drinking water and salt as a postcoital contraceptive method may seem harmless, it poses certain risks and dangers:

1. False Sense of Security:

By relying on this method, individuals may develop a false sense of security regarding contraception, potentially leading to an increased risk of unintended pregnancies.

It is crucial to emphasize that unconventional practices are no substitute for proven and reliable contraceptive methods.

2. Dehydration and Electrolyte Imbalance:

Consuming excessive amounts of saltwater can disrupt the body’s fluid balance, leading to dehydration and electrolyte imbalances.

High levels of sodium intake can cause adverse effects on blood pressure and kidney function as well.

3. Gastrointestinal Disturbances:

Drinking saltwater can result in gastrointestinal disturbances such as nausea, vomiting, diarrhea, and abdominal discomfort.

These unpleasant effects can have significant health implications and disrupt daily activities.
