Corpus luteum secretes a hormone called.
A) Prolactin
B) Progesterone
C) Aldosterone
D) Testosterone

Explanation

Solution

The endocrine system is composed of endocrine glands that secrete hormones released directly to the bloodstream. The female ovary is a gland that synthesises different hormones that are involved during the reproduction and menstruation process.

Complete answer:
A yellow hormone secreting body that is present in the female reproductive system is the Corpus Luteum. It is made inside the ovary at the follicle site, where the ovary gets matured and releases the ovum and the whole process is considered as ovulation.

The Corpus Luteum is synthesised from lutein cells that develop just after the ovulation process, during which the lipid and the yellow pigment accumulate inside the granulosa cells that line the follicle. The Corpus Luteum size is highly different.

Now let us find solution from given options:
A) Prolactin : It is synthesised from the anterior pituitary gland and is responsible for ejection of the milk.
B) Progesterone : The corpus luteum is involved in the secretion of oestrogen and progesterone, it leads to some changes in the uterus so that it becomes more suitable for the fertilization process but if the egg does not get fertilized the Corpus Luteum becomes inactive and menstruation occurs after 10-14 days.
C) Aldosterone : It is a hormone that is involved in which is helpful in maintaining the functions of renal tubules and is synthesised from adrenal gland.
D) Testosterone : It is a male sex organ that is responsible for primary sexual characteristics such as development of hairs and it is synthesised from testes.

Hence the correct answer is option ‘B’ i.e, progesterone.

Note: The structure of the Corpus Luteum starts to develop after maturation of egg pops out of the follicle. This hormone is necessary for conception and pregnancy to last. The process of fertilization will occur or not depends on this cell and if cysts formation takes place in this cell it causes very painful symptoms.
