Today in “Things You (Probably) Wouldn’t Guess:” Scientists have discovered that the presence of tonsils or an appendix affects fertility.
A study conducted by University of Dundee and University College London found that if woman had either organ removed, they were more likely to both to become pregnant, but also to get pregnant earlier in life. (If you remember from middle school math class, this is what’s called an inverse relationship.) The study followed 530K+ women in the UK over a 15-year period. Over 54K women had their appendix removed, 112K+ women had their tonsils removed, and 10K+ women had both appendices and tonsils removed.
Women who’d had their appendix removed got pregnant at a 34% higher rate than women who still had their appendix. Women who’d had their tonsils removed got pregnant at a 49% (!) higher rate than women who still had their tonsils. And women who’d had both procedures got pregnant at a 43% higher rate than women who had not undergone both procedures.
It’s not clear yet why these things are linked together. But it flies in the face of long-time conventional medical wisdom, which had previously declared that removing a woman’s appendix affected her future fertility due to scarring around her fallopian tubes (a crucial passage for her eggs).
