When it comes to birth control effects on a fetus, the opinions of the specialists differ drastically. While some of them claim that there is no danger in taking contraceptive pills while you are pregnant, because their active substances do not cross the placenta, others present a whole list of deficiencies that can occur because of them. Here are the 5 most important effects.

The limbs, heart or lungs

Besides decreasing the level of hormones that play an important role in the evolution of the pregnancy, contraceptive pills can deprive the fetus of a part of the vitamins and minerals it needs for a normal development. This way, abnormalities of the limbs, heart or lungs may appear.


Hermaphroditism is another condition that can affect the fetus, if you are on birth control during pregnancy. The condition affects especially the female fetuses that develop a set of reproductive male organs, besides their own ones, that are dominant. The main cause of this condition is given by the prolonged exposure of hydroxyprogesterone and norethidrone, two synthetic progestogens contained in high doses in most of the contraceptive pills.


Preeclampsia is also among the birth control effects on a fetus. This condition consists in the mother having an unusually high blood pressure that affects her and the unborn child equally. Although many pregnant women who do not use birth control pills after the moment of conception also suffer from preeclampsia, the incidence is lower than in the case of those who do.

The liver

The liver is another organ of the fetus that can be influenced by the component of the birth control pills. The main factor is the poor absorption of bilirubin, a waste secretion of the blood’s red cells. Instead of being eliminated from the child’s body, this product stocks in the liver. Because of this, the baby may be born jaundiced.

The bladder and the prostate

The bladder and the prostate of the baby are two other organs that can be affected if you take birth control pills during pregnancy. These organs can be deformed, and the child may suffer from various affections related to them, once he or she grows up.
