Question

The location of Leydig cells and their secretion is
A.Ovary and Estrogen
B.Liver and Cholesterol
C.Pancreas and glucagon
D.Testis and testosterone

Answer 1

Leydig cells are also referred to as interstitial cells. Leydig cells are polyhedral fit as a fiddle and have an enormous noticeable core, an eosinophilic cytoplasm, and various lipid-filled vesicles. No other interstitial cell has a nucleus and relatively the identification becomes easy.

Complete step by step answer: Leydig cells, otherwise called interstitial cells of Leydig, are discovered contiguous to the seminiferous tubules in the gonad. They produce testosterone within the sight of luteinizing hormone (LH).
1. The mammalian Leydig cell is a polyhedral epithelioid cell with a solitary unusually found ovoid core.
2. The core contains one to three noticeable nucleoli and a lot of dim recoloring fringe heterochromatin.
3. The acidophilic cytoplasm as a rule contains various layer bound lipid beads and a lot of smooth endoplasmic reticulum (SER).
4. Other than the undeniable wealth of SER with dissipated patches of endoplasmic reticulum, a few mitochondria are likewise unmistakable inside the cytoplasm.
5. These considerations have no known capacity, are found in under portion of all Leydig cell tumors, yet serve to secure the conclusion of a Leydig cell tumor.
6. Leydig cells discharge a class of hormones called androgens (19-carbon steroids).
7. They release testosterone, androstenedione, and dehydroepiandrosterone (DHEA) when animated by the luteinizing hormone (LH) which is delivered from the pituitary because of gonadotropin delivering hormone which is delivered by the nerve center.
So, the correct option is (D) Testis and testosterone.

Additional information:
Ovary and Estrogen- Ovaries are a part of the female reproductive system and Estrogen is the hormone released by it.
Liver and Cholesterol- Liver is the largest organ in the human body and it is responsible for producing bile and Cholesterol.
Pancreas and Glucagon- It is another organ situated in the human body and is responsible for producing hormones like Insulin and Glucagon .

Note: Leydig cells often termed as interstitial cells of Leydig, are found in males and are polyhedral in shape. They are a part of seminiferous tubules and are found in the male reproductive system. They contain acidophilic cytoplasm and the hormones released by them are termed as Androgens.
