Spermatozole

Question
Hello,

My 10-year-old son was diagnosed with and had a cyst removed from his left epididymis (spermatozole)... could this be a symptom of cystitis fibrosis?
Answer
Dear Parents,

In my experience, there is no connection between a spermatocele and cystic fibrosis (CF).

A spermatocele is not uncommon and can certainly occur in boys with CF, but it is not recognized as a cause of cystic fibrosis.

Now that your son has had this spermatocele diagnosed and removed, you don't need to worry that CF is the underlying cause.

I assume that your son has developed well and is not experiencing any symptoms or showing any unusual behavior.

I wish you all the best for your son's health!

Sincerely,

H.-E. Heuer
