    In this section, we’ll take a look at the remainder of our male reproductive tract. We have completed our discussion of penile pathology here. We’ll take a look at pathology of testis, epididymis, and the scrotum. Once again, picture what these look like. know as to where we are, so that you’re able to clearly understand the pathogenesis of each one of these conditions. Our topic at first is cryptorchidism. When I began the discussion, we began our male reproductive by looking at congenital issues embryologically. And we looked at the testis beginning in the abdomen and if it’s not properly pulled down by the gubernaculum into the scrotum, this is then called cryptorchidism. Let’s go into details. One or both undescended testis. Majority of which are located in the inguinal canal. Can you picture that? Normally, they should be resting in the scrotum. However, it didn’t quite make it and the testis is stuck in the inguinal canal Majority of them are. Could they be back in the abdomen? Sure. But go with the common. There’s impaired spermatogenesis, as you can imagine, if the testis aren’t properly located in the scrotum. You need that optimum temperature of 37 degrees, right? And if you don’t have that 37 degrees Celsius, then it’s difficult for a male to undergo spermatogenesis. And so therefore – well look for – A different physiology question of this would be if you have a male that’s in different temperatures, right? Environments. And so therefore, may not be the most conducive to spermatogenesis Even for example, bicyclists and what do they do? They sit on that seat for hours and hours and hours. And that disrupts proper spermatogenesis. No joke. Meaning to say that even lifestyle and the way that you lead it could have serious...
