The worms mate inside the host, in which the females also lay their eggs, to be passed out in the host's feces into the environment to start the cycle again. N. americanus can lay between nine and ten thousand eggs per day, and A. duodenale between twenty-five and thirty thousand per day.
Once in the trachea, the worms are coughed up into the pharynx and then swallowed again, after which they pass through the stomach and into the small intestine, where they mature into adult worms. [ 5 ] [ 7 ] The adult worms begin producing fertilized eggs within 60–65 days of being swallowed; [ 7 ] females produce as many as 200,000 eggs per ...

If one simply pulls off the protruding head of the worm, the worm will break and leak high levels of foreign antigen which can lead to anaphylactic shock and fast death of the host.
After a few weeks, young worms emerge and begin to feed in the soil. In the early juvenile phase, the worms do not develop the vertical burrows typical of adults. Adulthood is likely to require a minimum of one year of development, with reproductive maturity reached in the second year. [ 1 ]
They do not have a mouth; therefore they cannot eat and need to find a host quickly if they hatch in the environment. Energy is needed to develop into a sporocyst. The first intermediate host can differ for different trematodes. [3]
Examining The Fertility Question. While births among middle-aged women are on the rise, the statistics paint only a partial picture of pregnancy at 40 (and beyond).
Studies so far have validated recommendations to treat infected pregnant women for hookworm infection during pregnancy. A review found that a single dose of antihelminthics (anti-worm drugs) given in the second trimester of pregnancy "may reduce maternal anaemia and worm prevalence when used in settings with a high prevalence of maternal ...
