So far we've seen the various
changes that occur in an adolescent.

In this video, we will be discussing
about an important concept of how

secondary sexual characters develop.

Wait a second.

Do we know what exactly these
secondary sexual characters are?

Secondary, sexual, charact.

They are characters that are
exclusive to the individual sex

of a person and are not primary.

What does this statement mean, by the way?

By the word sex?

I mean the sex of the
individual, male or female?

By not primary.

I mean the characters which are not
required for the process of reproduction.

That's why we call them secondary.

In boys for instance,
there is a growth of.

Have you ever seen girls
having a long or trimmed beard?

Of course not.

However, it is an exclusive character
of males which is not found in females.

So this is the simplest example
to understand the concept of

secondary sexual characters.

Let us understand the
concept with another example.

In case of females, one extremely
important physical change during

puberty is the enlargement of breasts.

It is exclusively found
in adolescent females.

So are there any other set of
secondary sexual characters

seen in males and females?

Yes, of course.

Apart from the growth of facial hair, the
growth of hair on the chest, under the

arms and in the pubic region are other
examples of secondary sexual charact.

Similarly in females, apart from breast
development, hair growth around the pubic

region and under the arms is also seen.

So in a nutshell, the secondary sexual
characters are those characters,

which are not really required as
a part of reproductive system.

But do you know what exactly
makes these secondary sexual

characters developed during puberty?

These characters are all thanks to
the hormones secreted by the gona.

Yes, hormones are the most
important players in this process.

The male gnats called testes secrete the
male sex hormone called the testosterone.

This is responsible for not only the
development of the reproductive tissues,

but also for the development of the
secondary sexual characters in males.

And the same is applicable to
the female sex hormone called the

estrogen secreted by the ovaries.

It brings about the development
of female reproductive tissues.

At the same time, it takes up
the responsibility of developing

the secondary sexual characters
in the female individuals.

Who do you think controls the activities
of these hormones in our body?

The hormones regulate several processes.

But who regulates the
secretion of these hormones?

Exactly.

The Mastermind to control all
the hormonal secretions is the

gland called the pituitary gland.

Next, we will talk about these
hormones, their major roles,

and how they bring about all the
necessary activities inside a body.
