Question

The function of the Corpus luteum is
A. Excretory
B. Digestive
C. Nervous
D. Endocrine

Answer 1

Hint: Corpus luteum is a small and important part of the female reproductive system. It is a temporary endocrine gland that is developed in the female ovary during ovulation. It has numerous functions in the reproductive processes.

Complete Answer:
- In this particular question, we can have a look at the functions of corpus luteum. It is the dynamic endocrine gland that secretes various hormones, which are its major functions in the endocrine system. Corpus luteum is formed from the granulosa and theca interna cells during ovulation occur in the graafian follicle.
- After ovulation secondary oocyte released due to that remains ruptured Graafian follicle which is further converted into the corpus luteum with the help of luteinizing hormone (LH) hormone. It is yellow in color.
- The main function of the corpus luteum is that it can produce different hormones such as progesterone, estrogen, inhibin, and androgen. Note that the most important function of the corpus luteum is the ability to produce progesterone hormones in a large amount.
- Progesterone is a chief hormone which is essential for the development and maintenance of the endometrium. The endometrium is necessary for the implantation of the fertilized ovum and other pregnancy events. Estrogen plays an important role in the menstrual cycle.
- The life span of the corpus luteum depends on whether the fertilization has occurred or not. If fertilization has not occurred its life span is 10-11 days and if fertilization has occurred its life span is 3 months or the first trimester of pregnancy. The other major function of corpus luteum after fertilization is embryo survival.
- Moreover, the trophoblast of the embryo has been fighting the gradual drop in the progesterone hormone by releasing human gonadotropin (similar to LH). It has been allowed the existence of the corpus luteum to expand during pregnancy until the placenta is capable to make enough progesterone and estrogen to maintain and support the uterus mucosa.

So, the correct answer to this question is option D ‘endocrine’.

Note: Corpus luteum has many functions in the female reproductive system such as in the menstrual cycle which secrets some hormones that play a key role in the pre-fertilization and post-fertilization processes. Corpus luteum are the endocrine system present with the ovaries and pose a significant role in producing hormones that are very important for the female reproductive system.
