One of those reasons is meconium aspiration, a condition where babies inhale a substance called meconium in utero a bowel movement in the amniotic fluid.
Babies exposed, in utero, can have deformities, delays in development, or seizures along with many other problems such as rash, fever, hepatosplenomegaly, anemia, and jaundice.
Since then, review studies have found that overall rates of congenital malformations in infants exposed to lamotrigine "in utero" are relatively low (1-4%).
There are other biological factors that are associated with hypersexuality such as premenstrual changes, and the exposure to virilising hormones in childhood or in utero.
