What happens if a man takes 5 birth control pills? A Pharmacological Review

4 min read

Birth control pills contain hormones designed for the female reproductive system. So, what happens if a man takes birth control pills? A single, isolated incident is unlikely to cause lasting harm but can induce immediate, unpleasant side effects like nausea and vomiting.

Quick Summary

If a man takes birth control pills, he will not gain any contraceptive benefit. Instead, he is likely to experience acute side effects like nausea, headaches, and mood changes from the hormonal surge.

Key Points

  • Immediate Sickness: A man taking birth control pills will likely experience acute nausea, vomiting, and headaches due to the sudden hormone surge.

  • No Contraceptive Effect: Female birth control pills are completely ineffective as a form of male contraception.

  • Hormonal Disruption: The pills introduce high levels of synthetic estrogen and progestin, which disrupt a man's natural testosterone-dominant hormonal balance.

  • Long-Term Dangers: Chronic use carries severe risks, including breast development (gynecomastia), reduced fertility, and a significantly increased risk of dangerous blood clots.

  • Single Dose vs. Chronic Use: A single ingestion's effects are temporary and unpleasant, while long-term use leads to lasting physical and medical consequences.

  • Seek Medical Advice: After an accidental ingestion, especially with severe symptoms, the recommended action is to contact a poison control center or a healthcare provider.

Birth control pills are one of the most common forms of contraception for women, relying on a formulation of hormones to prevent pregnancy. A frequent question that arises out of curiosity or concern over accidental ingestion is what happens if a man takes these pills. Taking a dose of these pills, while not typically life-threatening, introduces a significant hormonal shock to the male body, leading to a range of predictable but unpleasant outcomes. It is critical to understand that these medications are not designed for male physiology and offer no contraceptive benefits for men.

The Hormones in Birth Control Pills

Most birth control pills are "combination pills" that contain two key synthetic hormones: estrogen and progestin. In the female body, these hormones work together to prevent ovulation (the release of an egg), thicken cervical mucus to hinder sperm, and alter the uterine lining to prevent implantation. While men also produce estrogen and progesterone naturally in small amounts for functions like bone health and testosterone regulation, the doses in contraceptive pills are substantial and meant to manipulate the menstrual cycle. Introducing a sudden, large dose of these hormones disrupts a man's natural hormonal balance, which is dominated by testosterone.

Immediate Effects of Taking Pills

When a man takes birth control pills, the most immediate and common reactions are due to the sudden spike in hormones, which the body treats as an overdose. These symptoms are generally not considered toxic or life-threatening but can be quite uncomfortable.

  • Nausea and Vomiting: This is the most widely reported reaction. The surge of estrogen can irritate the stomach lining, leading to feelings of sickness.
  • Headaches and Dizziness: Hormonal fluctuations are a common trigger for headaches.
  • Mood Swings: The introduction of high levels of female hormones can cause temporary emotional changes or irritability.
  • Breast Tenderness: Even a single large dose can sometimes cause temporary breast soreness or tenderness. In most cases of a one-time ingestion, these effects will subside within a day or two as the body metabolizes and expels the excess hormones. For guidance, especially if symptoms are severe, contacting a poison control center is the recommended first step.

Comparison of Single Dose vs. Chronic Use

It's crucial to distinguish between a single incident and regular, long-term use. While a one-time dose has minimal long-term impact, chronic ingestion carries significant health risks and causes profound physical changes. The estrogen found in birth control pills is also associated with a higher risk of deep vein thrombosis (blood clots).

Feature Single Dose (e.g., a few pills) Chronic or Repeated Use
Immediate Symptoms Nausea, vomiting, headache, mood swings Acne, weight gain, mood changes
Reproductive System No contraceptive effect, no impact on fertility Decreased sperm count, testicular shrinkage, infertility
Physical Changes None expected Breast development (gynecomastia), fat redistribution to hips, softer skin, reduced facial hair
Sexual Function No significant impact Decreased libido, erectile dysfunction
Serious Health Risks Very low; primarily acute discomfort Increased risk of blood clots (thrombosis), heart attack, and other cardiovascular issues

Debunking the Myth: Male Contraception

Taking female birth control pills will not act as a male contraceptive. The hormones in these pills are designed to stop ovulation, a process that doesn't occur in men. They do not work to block sperm production in a reliable or safe manner. While chronic use can lower sperm count by suppressing testosterone, this is a dangerous and unapproved method that comes with the serious side effects listed above. Research into a viable male birth control pill is ongoing, but these efforts focus on different hormonal or non-hormonal mechanisms that target sperm production directly and safely.

Conclusion: A Risky Experiment with No Benefit

In summary, if a man takes birth control pills, he should prepare for a bout of nausea, headaches, and other unpleasant, short-lived side effects. The act provides no contraceptive protection and does not serve as a safe method for any purpose. While a single accidental ingestion is unlikely to cause permanent damage, it highlights the importance of using medications only as prescribed. Repeated use poses severe health risks, including feminizing effects and life-threatening blood clots. If ingestion occurs, monitoring symptoms and contacting a medical professional or poison control for advice is the safest course of action.

Frequently Asked Questions

Taking a single birth control pill is highly unlikely to cause any noticeable or harmful effects for a man. At most, some might experience very mild nausea.

Long-term use can lead to significant changes, including the development of breast tissue (gynecomastia), shrinking testicles, reduced facial hair, decreased libido, and a serious increased risk of blood clots (deep vein thrombosis).

With chronic use, the estrogen in birth control pills can suppress the body's natural production of testosterone. A single dose is unlikely to have a lasting impact on testosterone levels.

Gynecomastia is the swelling or enlargement of breast tissue in males, which is caused by a hormone imbalance, specifically too much estrogen relative to testosterone. It is a potential side effect of long-term estrogen exposure.

While not typically considered life-threatening, taking multiple pills is an overdose that can cause significant discomfort, including nausea, vomiting, and headaches. It is recommended to contact Poison Control for guidance.

Female birth control pills are designed to prevent the release of an egg (ovulation) in women. They do not have a mechanism to stop the production of sperm in men, making them ineffective for male contraception.

A hospital visit is usually not necessary for a single, accidental ingestion unless symptoms are severe, like persistent vomiting, difficulty breathing, or sudden pain. The best first step is to call a 24/7 poison control hotline for advice.
