Before going any further into the chapter, let's just review some basic terminology. So we're going to begin with the primary sex organs, and these are also known as the gonads. So the primary sex organs for males are going to be the testes, and the primary sex organs for females are going to be the ovaries. So the testes and the ovaries are going to be the location where sex hormones are produced as well as where gametes are produced. Scooching down here to our second row, gametes are reproductive cells. And so for males, the gametes are the sperm, and for females, the gametes are the ova or the egg.
Now moving on to sex hormones. So sex hormones are just hormones that are specialized to assist in the maturation and function of reproductive organs, as well as having various other functions throughout the human body. Like all hormones, they are very complex. We will have a whole bunch of videos on sex hormones coming up later in the chapter. But for males, the primary sex hormone is testosterone. And for females, the primary sex hormones are estrogen and progesterone. Now, I do want to be clear, males do produce estrogen and progesterone, and females do produce testosterone. Those are simply just produced in lower levels. So in males, the primary hormone is testosterone, and then for females, the primary sex hormones are estrogen and progesterone. But all three of these are produced in males and females.
And then finally, we're going to be talking about accessory reproductive organs and accessory reproductive organs include things like ducts, glands as well as external genitalia, and that is true for both males and females.
Alright. So now that we got that out of the way, I will see you in our next video. Bye bye.
