It's complicated; the effect of worms on fertility appears to depend on the specific type of worm. Research suggests that certain worm infections may increase the likelihood of pregnancy, while others may decrease it. Specifically, roundworm infection seems to correlate with a higher chance of pregnancy, while hookworm infection seems to correlate with a lower chance of pregnancy.
Here's a breakdown:
-
Roundworm (Ascaris lumbricoides): Studies indicate that women infected with roundworm were more likely to become pregnant. The exact mechanisms behind this are still under investigation.
-
Hookworm (Necator americanus and Ancylostoma duodenale): Conversely, research suggests that hookworm infection is associated with a reduced chance of pregnancy.
It's important to note that this is a complex area of research, and more studies are needed to fully understand the relationships between different types of worm infections and fertility. Factors like the intensity of the infection, the woman's overall health, and other environmental factors can also play a role.
