Which of the following hormones is detected in the blood of a human female, only during pregnancy?
- AFollicle Stimulating Hormone
- Correct answerBHuman Placental Lactogen
- CLuteinising Hormone
- DProgesterone
Solution
Human Placental Lactogen (hPL), Human Chorionic Gonadotropin (hCG), and relaxin are hormones that are produced in women only during pregnancy.
Follicle Stimulating Hormone (FSH) and Luteinising Hormone (LH) are gonadotropins secreted by the anterior pituitary gland and regulate the normal menstrual cycle.
Progesterone is secreted by the corpus luteum during the luteal phase of the menstrual cycle and by the placenta during pregnancy. Thus, it is present in both pregnant and non-pregnant females.
Therefore, Human Placental Lactogen is detected only during pregnancy.
