According to a study published in US National Library of Medicine by National Institutes of Health in a study conducted over 97 pregnant women and 3 non-pregnant women, 90% of the pregnant women experienced bitter and sour taste.

What are the Causes of Metallic Taste during Pregnancy?

The excess progesterone and estrogen that is produced during pregnancy to aid the growth of one’s baby causes the changes in the sensory actions. Taste and smell are the two senses most affected.  Dysgeusia is caused by the pregnancy hormone oestrogen. Oestrogen content and secretion is high in pregnant women. Oestrogen also determines our sense of taste, food aversion and food craving. Since oestrogen levels vary drastically during pregnancy which can affect your perception of food.

During pregnancy one develops a more heightened sense of smell than usual. A strong and unappealing odour can be even more putting off and there are chances of that causing a metallic aftertaste in your mouth. Water retention increases during pregnancy all over the body system and also affects the taste buds, which might aid this metallic taste in your mouth.

There is no conclusive symptom for the gender of the child, although there is popular wisdom passed down from generation to generation. Each pregnancy is unique in its own way and a metallic taste cannot determine the sex of your child.
