Up to 15% of all men and 40% of men with infertility have varicocele—an abnormal dilation of veins in the scrotum that can impair sperm production and quality.
At Fertilite, we frequently see couples unaware that male factors account for nearly 50% of infertility cases. Detecting and treating varicocele can significantly improve reproductive outcomes, both naturally and through assisted reproduction techniques.
Reproductive health is not just a female issue—male evaluation is essential.
What is Varicocele?
Varicocele is similar to a varicose vein but occurs in the pampiniform plexus, a group of veins in the spermatic cord. This dilation impairs blood drainage, raising scrotal temperature and generating oxidative stress, both of which negatively affect sperm.
Symptoms and Diagnosis
Most varicoceles are asymptomatic, but signs may include:
- Scrotal heaviness or discomfort
- Visible or palpable veins
- Testicular asymmetry or shrinkage
- Abnormal semen parameters
Diagnosis involves:
- Physical examination
- Scrotal Doppler ultrasound
- Semen analysis
You can’t improve what you don’t measure—semen analysis is the essential first step.
How Does Varicocele Affect Fertility?
Varicocele impacts fertility by:
- Reducing sperm count and motility
- Increasing sperm DNA fragmentation
- Altering testicular hormone production
- Raising the risk of abnormal morphology
Varicocele is the most treatable cause of male infertility.
When Should Varicocele Be Treated?
Treatment is recommended when:
- The couple experiences unexplained infertility
- The varicocele is clinically palpable
- There are abnormalities in the semen analysis
- The patient experiences chronic scrotal pain
- Fertility preservation is desired
Treatment options include:
- Microsurgical varicocelectomy
- Laparoscopy
- Embolization
What to Expect After Treatment
Most men treated for varicocele experience:
- Improvement in semen parameters within 3–6 months
- Reduced scrotal pain, if present
- Higher chances of natural conception or improved outcomes with IVF
Correcting a varicocele can make the difference between years of trying and successful parenthood.
Conclusion
At Fertilite, we promote an integrated view of fertility. Evaluating the male partner from the start helps detect treatable conditions like varicocele and maximize reproductive success.
Fertility is a shared journey—and it begins with the right diagnosis.
