Hello everyone, in this question we have been said that the secondary sex characteristics are physical and behavioral characteristics that basically appear during the puberty and not directly related to reproduction.
00:16
So, the secondary sex characteristics in males include a deepening voice, more facial hair, larger muscle mass and increased aggressiveness.
00:26
So, unlike these traits, the sperm production is a primary sex characteristic in males because it is directly involved in reproduction.
00:35
So, here three boxes have been given that is of the androgens, the estrogen and progesterone and here neither is written.
00:46
So, androgen are basically the crucial for male sexual and reproductive function.
00:51
They are also responsible for the development of the secondary sexual characteristic in male that may include the facial and the body hair growth and also the voice change because of the androgen.
01:08
So, androgens also affect the bone as well as the muscle development and also the metabolism is increased.
01:18
So, they generate the anabolic effect on carbohydrate metabolism and protein and they play a critical stimulatory role in the phenomena of the spermatogenesis as they act on a central neural system influencing the male sexual behavior.
01:35
So, here we will write the testosterone in the androgen box.
01:42
Also, we will write the deepening of voice as well as the development of the facial hair.
01:56
The increased aggressiveness will also be in this.
02:02
Also there will be increased muscle mass.
02:07
So, this here is for the androgen and then for the estrogen and progesterone, these are basically the steroid hormones that play a pivotal role in the regulation of the mammalian reproduction...
