Side Effects of Male Birth Control

Male birth control methods, both hormonal and non-hormonal, are under active development. While they hold promise for expanding contraceptive choices, it’s important to understand the potential side effects of male birth control before deciding if it’s right for you.

Overview of Hormonal Male Birth Control

Hormonal approaches work by suppressing sperm production through combinations of testosterone and progestin (or similar agents). Several clinical trials have evaluated:

• Intramuscular injections (testosterone + progestin) every 1–3 months
• Daily oral pills (testosterone undecanoate or dimethandrolone undecanoate)
• Transdermal gels applied to the skin

Common Side Effects of Hormonal Methods

Most trial participants report mild to moderate effects, which often improve over time:

• Changes in libido
  • Some men notice a decrease in sex drive; others report no change or even an increase.
• Weight gain
  • A small average gain (1–3 kg) over several months.
• Acne and oily skin
  • Similar to puberty; usually transient or manageable with topical treatments.
• Mood changes
  • Irritability, mild depression or anxiety in a minority of users.
• Injection-site reactions
  • Pain, redness or swelling for injections; less common with gels.

Less Common or Reversible Effects

• Altered lipid profiles
  • Small decreases in “good” HDL cholesterol; reversible after stopping treatment.
• Changes in testicular volume
  • Testes shrink slightly due to reduced sperm production; size returns to normal once therapy ends.
• Mild fatigue or headaches

Non-Hormonal Male Birth Control

Non-hormonal approaches aim to block or inactivate sperm without changing hormone levels. Examples include:

• Vasalgel/ RISUG®
  • A gel injected into the vas deferens to physically block sperm.
• Heat-based methods
  • Devices that raise scrotal temperature to reduce sperm count.
• Sperm-binding agents
  • Chemicals applied into the vas deferens to immobilize sperm.

Side Effects of Non-Hormonal Methods

• Injection discomfort
  • Pain or swelling at the injection site for Vasalgel/RISUG.
• Reversal procedures
  • Uncertain success rates in fully restoring fertility.
• Local irritation
  • Mild inflammation or discomfort in the scrotal/inguinal area.

Comparing Side Effects of Male Birth Control

Category	Hormonal Methods	Non-Hormonal Methods
Systemic effects	Libido changes, weight gain, mood shifts	Minimal systemic effects
Local reactions	Injection-site pain (injections), skin irritation (gels)	Injection discomfort, mild local irritation
Reversibility	Generally reversible in 3–6 months after stopping	Variable; some may require additional procedures
Onset of action	Several weeks to suppress sperm	Rapid (once gel is in place)

Managing and Monitoring Side Effects

Most side effects of male birth control are mild and manageable:

• Regular check-ups
  • Monitor blood pressure, weight, mood and lipid panels.
• Skin care
  • Use gentle cleansers or topical acne treatments if needed.
• Lifestyle adjustments
  • Balanced diet and regular exercise help control weight gain.
• Open communication
  • Discuss mood or libido changes with your partner and healthcare provider.

If you experience anything unexpected—such as severe mood disturbances, chest pain, difficulty breathing, or signs of a serious allergic reaction—seek immediate medical attention.

When to Seek Professional Help

While most side effects of male birth control are not life-threatening, it’s important to recognize warning signs:

• Severe depression or suicidal thoughts
• Chest pain or palpitations
• Sudden shortness of breath
• Unexplained swelling (e.g., legs or face)
• High fever or signs of infection at an injection site

For any symptom that feels serious, life threatening, or lasts longer than expected, speak to a healthcare professional right away. You might also consider a free, online symptom check, using the doctor approved Ubie Symptom Checker.

Balancing Risks and Benefits

Deciding on male birth control involves weighing potential side effects against the benefits of shared contraceptive responsibility:

• Pros
  • Empowers men with more control over fertility
  • Reduces contraceptive burden on female partners
  • High efficacy in trials
• Cons
  • Side effects (most mild)
  • Ongoing research—few products are widely available yet
  • Possible need for follow-up reversals in non-hormonal methods

Final Thoughts

The side effects of male birth control vary by method but are generally mild and reversible. Hormonal options can cause systemic changes like weight gain or mood shifts, while non-hormonal methods mainly pose local injection or procedure-related discomfort. Clinical trials continue to gather data on long-term safety and effectiveness.

Before starting any regimen:

1. Review your personal and family medical history
2. Discuss risks and benefits with a healthcare provider
3. Schedule routine follow-up appointments
