Does tonsillectomy affect fertility?

No. I was asked this a lot in san diego by mexican families. Also I have been asked this by south american families. There is a misconception about this phenomenon in certain cultures, but no medical evidence to show any impact on fertility from tonsillectomy.
No. In general ear, nose and throat infections will not have an impact on fertility in any direct way. There may be rare situations such as tonsillar tuberculosis that may have a fertility impact, but this is due to the tuberculosis, not to the tonsillitis per se.
