Question

Select the option which correctly matches the endocrine gland with its hormone and its function.

• A. Corpus luteum – Estrogen – Essential for the maintenance of the endometrium
• B. Placenta – Estrogen – Initiates secretion of the milk
• C. Ovary – FSH – Stimulates follicular development and the secretion of estrogens
• D. Leydig’s cells – Androgen – Initiates the production of sperms

Answer 1

The correct option is D

Leydig’s cells – Androgen – Initiates the production of sperms

The correct option is D.

Explanation for the correct option:

1. Leydig cells are present in the interstitial spaces in the testicular lobules
2. Leydig's cells secrete male hormones called androgens like testosterone.
3. Testosterone is responsible for stimulating the process of spermatogenesis.
4. Spermatogenesis is the process of producing sperm from sperm mother cells.
5. Androgens also regulate the development of accessory sex organs, secondary sexual characteristics and influence libido.

Explanation for the incorrect options:

Option A:

1. Every single month in women of childbearing age, a cyst called the corpus luteum develops on the ovary.
2. This cyst is essentially a collection of ovaries-located cells that develops during each menstrual cycle enzyme.
3. A transient endocrine gland called the corpus luteum forms in the human body from the burst follicle during the luteal phase after ovulation.
4. It is essential for maintaining early pregnancy since it is a major source of steroid hormones, particularly progesterone.

Option B:

1. The placenta produces estrogen which is responsible for producing pregnancy changes in females.

Option C:

1. Ovaries secrete three hormones namely estrogen, progesterone, and relaxin.
2. Estrogens stimulate the development of the female reproductive tract and also in the development of accessory sexual characters in females.
3. Progesterone suspends the process of ovulation, promotes the development of mammary glands, and inhibits contraction of the uterus during pregnancy.
4. Relaxin is responsible for relaxing the pelvic ligaments and cervix of the mother during the birth of the child.

Final answer: The correct pair is Leydig's cells that secrete androgens which initiates the production of sperms.
