Which of the following hormones is not secreted by human placenta?
Which of the following hormones is not secreted by human placenta?
- FSH
- hCG
- Relaxin
- Progestogen
The Correct Option is A
Approach Solution - 1
Let's consider each hormone and its role in pregnancy:
- FSH (Follicle-Stimulating Hormone): FSH is a gonadotropin hormone produced by the pituitary gland. It's essential for the development of ovarian follicles in females and sperm production in males. While FSH plays a role in the menstrual cycle and preparing the body for pregnancy, it's NOT secreted by the placenta itself.
- hCG (Human Chorionic Gonadotropin): hCG is produced by the placenta shortly after implantation. It maintains the corpus luteum, which continues to produce progesterone and estrogen, essential for maintaining the pregnancy in the early stages.
- Relaxin: Relaxin is produced by the corpus luteum and later by the placenta. It helps to relax the ligaments in the pelvis and soften the cervix, preparing the body for childbirth.
- Progestogen (Progesterone): Progesterone is initially produced by the corpus luteum and later by the placenta. It's crucial for maintaining the uterine lining, preventing uterine contractions, and supporting the development of the fetus.
Therefore, the hormone NOT secreted by the human placenta is FSH.
Approach Solution -2
The hormone that is not secreted by the human placenta is FSH (Follicle-Stimulating Hormone).
FSH is a hormone primarily secreted by the pituitary gland in both males and females. It plays a crucial role in the regulation of reproductive processes, such as the development and maturation of ovarian follicles in females and the production of sperm in males.
While the placenta plays a vital role in the production and secretion of various hormones during pregnancy, it does not produce FSH. FSH production is regulated by the anterior pituitary gland.

Biomolecules - Hormones
Hormones are defined as important chemicals that act as messengers of the body. These are the chemicals that are secreted by special glands, known as endocrine glands and these distributed throughout the body. It helps in controlling of physiological functions. Moreover, they are important while maintaining homeostasis in the body. The entire endocrine system is a network of glands. Hormones are almost same as the nervous system. Functioning of various body functions it plays an important role. The only difference between the nervous system and hormones that nervous system uses nerve impulses and neurotransmitters for communication, while the endocrine system uses chemical messengers named hormones.
Types of Hormones:
- Peptide Hormones: Peptide hormones include amino acids that are soluble in water. Insulin is a vital peptide hormone that is produced by the pancreas.
- Steroid Hormones: Unlike peptide hormones, steroid hormones are fat-soluble and can easily pass through a cell membrane with ease. Sex hormones like testosterone, estrogen, etc. are some of the kinds of steroid hormones.
