Do’s & Don’t: Hypospadias In Next Children Prevention
Quick Answer
If your first child was born with hypospadias, your concern about future pregnancies is completely understandable - but take heart. While there is a slightly increased risk (about 7-8% compared to 0.3-0.5% in general population), the majority of subsequent boys are born without this condition. There are several evidence-based steps you can take before and during pregnancy to reduce risk, though no method guarantees prevention since the exact cause is often unknown.
What is Hypospadias?
Watch: Iron is most important fuel for 🧠 growth. You need to include iron rich food in your babies diet.
Hypospadias is a common congenital condition in boys where the urinary opening (meatus) is located on the underside of the penis rather than at the tip.
Key Facts:
Occurs in approximately 1 in 200-300 boys
Develops during early pregnancy (8-14 weeks)
Can range from mild to severe
Usually correctable with surgery
NOT caused by anything parents did wrong
Severity Levels:
Type
Location of Opening
Treatment
Distal (mild)
Near tip
May not need surgery
Midshaft (moderate)
Middle of penis
Surgery usually needed
Proximal (severe)
Near scrotum
Surgery required
Understanding Your Risk for Future Pregnancies
Family History Impact:
Situation
Risk for Next Son
No family history
0.3-0.5% (general population)
One affected son
7-8%
Father has hypospadias
8-10%
Two affected sons
Higher (discuss with geneticist)
Father + one son affected
Highest
Important: While risk increases with family history, remember that even with one affected child, there's a 90%+ chance the next son will NOT have hypospadias.
What Causes Hypospadias?
The exact cause is often unknown (multifactorial), but may involve:
Genetic Factors:
Family history
Genetic mutations affecting hormone signaling
Hormonal Factors:
Disruption of testosterone/DHT during development
Endocrine disruptors in environment
Environmental Factors:
Certain chemical exposures
Some maternal medications
Possibly certain environmental pollutants
Maternal Factors:
Advanced maternal age
Obesity
Fertility treatments (some studies)
Gestational diabetes (possibly)
Prevention Strategies: What You CAN Do
Before Pregnancy (Pre-Conception)
1. Achieve Healthy Weight
Maintain healthy BMI (18.5-24.9)
Maternal obesity is linked to higher risk
Work with doctor on weight loss if needed
Don't crash diet - gradual, healthy changes
2. Start Folic Acid Early
Take 400-800 mcg daily at least 1-3 months before conception
Continue through first trimester
May help reduce risk of various birth defects
Available as supplements or in fortified foods
3. Quit Smoking
Smoking during pregnancy linked to hypospadias risk
Quit well before trying to conceive
Seek help if needed (nicotine replacement, counseling)
Partner should also quit (secondhand smoke)
4. Stop Alcohol
Alcohol exposure during early pregnancy may affect development
Since you won't know immediately when pregnant, stop before trying
No "safe" amount during pregnancy
5. Review Medications with Doctor
Some medications may increase risk
Discuss all prescription and over-the-counter drugs
Never stop prescribed medications without doctor advice
Consider alternatives if needed
6. Medical Check-Up
Control any chronic conditions (diabetes, thyroid)
Check hormone levels if indicated
Discuss family history with doctor
Consider genetic counseling
During Pregnancy
1. Continue Folic Acid
Through at least first 12 weeks
Prenatal vitamins contain adequate amounts
2. Nutritional Balance
Eat balanced diet with adequate protein
Some studies suggest vegetarian diet may be associated with slightly higher risk - ensure adequate protein, iron, zinc
Include iron-rich foods (meat, legumes, leafy greens)
Adequate zinc intake
3. Avoid Environmental Exposures
Limit exposure to pesticides
Avoid unnecessary chemicals
Be cautious with plastics (avoid heating food in plastic)
Filter drinking water if concerned about quality
4. Regular Prenatal Care
Attend all scheduled appointments
Report any concerns to doctor
Follow all recommended tests
5. Manage Stress
Chronic stress may affect hormones
Practice relaxation techniques
Seek support when needed
What to AVOID
Avoid
Why
Smoking
Linked to higher risk
Alcohol
May affect fetal development
Certain medications
Some may disrupt hormones (discuss with doctor)
Excessive soy products
Phytoestrogens (controversial, but moderation advised)
Pesticide exposure
Environmental hormone disruptors
BPA plastics
Endocrine disruptor (avoid microwaving plastic)
Recreational drugs
Various developmental effects
Extreme dieting during pregnancy
Nutritional deficiencies
Genetic Counseling
Consider genetic counseling if:
Multiple family members affected
Both father and child have hypospadias
Other genital or urinary abnormalities in family
You want detailed risk assessment
You have questions about testing options
What Genetic Counselors Can Offer:
Detailed family history analysis
Accurate risk calculation
Discussion of any genetic testing options
Emotional support and guidance
Connection to support groups
Early Detection During Pregnancy
Hypospadias is sometimes visible on detailed ultrasound
Not always detectable before birth
If suspected, additional evaluation may be offered
Early awareness helps with planning (though doesn't change outcome)
If Your Next Child Has Hypospadias
Take Comfort:
Modern surgery has excellent outcomes
Most repairs are done as outpatient
Boys with corrected hypospadias have normal urinary and sexual function
You'll have knowledge and experience from first child
Surgeon familiarity with your family history

FAQs
Q: Mera pehla beta hypospadias ke saath paida hua - next baby mein kya chance hai?
A: If your first son has hypospadias, the chance of the next son having it is approximately 7-8% (compared to 0.3-0.5% in general population). This means there's still a 90%+ chance your next son will NOT have this condition. Taking preventive measures like folic acid, healthy weight, and avoiding smoking can help reduce risk further.
Q: Can eating meat during pregnancy prevent hypospadias?
A: Some studies have suggested that vegetarian diets during pregnancy may be associated with slightly higher rates of hypospadias, possibly due to phytoestrogens in soy or nutritional factors. However, this is not conclusive. The key is ensuring adequate protein, iron, and zinc regardless of diet type. If vegetarian, consider supplements and consult with your doctor.
Q: At what stage of pregnancy does hypospadias develop?
A: The penis develops and the urethra forms between 8-14 weeks of pregnancy. This is the critical window when hypospadias occurs. This is why pre-conception and early pregnancy measures (folic acid, avoiding harmful substances) are most important.
Q: Is there any test during pregnancy to detect hypospadias?
A: Hypospadias can sometimes be detected on detailed ultrasound (level II or anomaly scan), typically done around 18-20 weeks. However, mild cases may not be visible before birth. If there's family history, your doctor may pay extra attention during ultrasound.
Q: If my husband has hypospadias, what is the risk for our children?
A: If the father has hypospadias, the risk for sons is approximately 8-10%. Combined with other family history, risk may be higher. Genetic counseling can provide more accurate assessment based on your specific situation.
Q: We're planning IVF - does this affect hypospadias risk?
A: Some studies have shown slightly higher rates of hypospadias in pregnancies from assisted reproductive technology (ART/IVF). The reasons aren't fully understood. If you're undergoing IVF, discuss this with your fertility specialist and follow all pre-conception recommendations carefully.
