Research has shown that women with latent toxoplasmosis and high antibody levels, meaning those that most likely became infected in the two‑year period before getting pregnant, are twice as likely to give birth to a boy. By contrast, women with low antibody levels, meaning those who have been infected for a long time, are more likely to give birth to a girl. That said, a baby’s sex is influenced by many different factors, so it can’t really be said that women with latent toxoplasmosis tend to have boys.
