Hormones play an important role throughout the life of a woman. While estrogen and progesterone are responsible for the occurrence of menstrual cycles and appearance of sexual characters in a woman, there are some hormones which are produced exclusively during pregnancy and lactation. Human Chorionic Gonadotropin hormone (hCG) and Human Placental Lactogen (hPL) are two of them.

hCG is produced during pregnancy, solely in the placenta. The level of this increases throughout the first trimester and is one of the reasons for nausea and vomiting associated with pregnancy. hPL, on the other hand, is produced by the placenta which stimulates the mammary glands in anticipation of breastfeeding.

The presence of hCG hormone is detected in either the blood or urine sample. The home pregnancy test kit works by detecting hCG in the urine sample. Watch this video to know how.
