Which is present in urine of pregnant woman
Show Hint
In a pregnant woman, urine contains human chorionic gonadotropin (hCG), a hormone produced by the placenta.
- HCG
- LH
- Estrogen
- FSH
The Correct Option is A
Approach Solution - 1
Human chorionic gonadotropin (HCG) is a hormone produced during pregnancy. It appears in the blood and urine of pregnant women as early as 10 days after conception.
- In a pregnant woman, urine contains human chorionic gonadotropin (hCG), a hormone produced by the placenta.
- An elevated level of HCG in the urine is a common indicator of pregnancy and is often used in pregnancy tests.
Other substances that may be present in a pregnant woman's urine include glucose, protein, and various electrolytes.
Approach Solution -2
The human chorionic gonadotropin (HCG) test checks blood or urine for the hormone HCG. It is used to confirm pregnancy or detect birth defects.
- The pregnancy test can detect HCG as early as 6 days after egg implantation.
- The levels of HCG rapidly rise in the first 14 to 16 weeks after the last menstrual cycle.
- It can also be produced by certain tumours and is used to check for molar pregnancy or cancer in the uterus.
Therefore, option A) is the correct answer - Human chorionic gonadotropin or HCG hormone is present in urine of pregnant woman.

Female Reproductive System
The female reproductive system provides various functions. The ovaries produce the egg cells known as the ova or oocytes. The oocytes are then taken to the fallopian tube where fertilization by a sperm may occur. The fertilized egg is then transferred to the uterus, where the uterine lining has thickened in regard to the normal hormones of the reproductive cycle. Once in the uterus, the fertilized egg can implant into the thickened uterine lining and continues to develop. If implantation does not take place, the uterine lining is shed as menstrual flow. In addition, the female reproductive system produces female sex hormones that preserve the reproductive cycle.
During menopause, the female reproductive system slowly stops making the female hormones that are required for the reproductive cycle work. At this stage, menstrual cycles can become irregular and finally stops. One year after menstrual cycles pause, the woman is deemed to be menopausal.
