No, it is not. That's why the testicles are not internal organs; this is where semen is produced. To be able to produce it, the testis need to be a bit cooler than regular body temperature.
The best temperatures that sperm are produced is 37oc. if the temperature is higher than this then the scrotum lowers and if its colder than this the scrotum contracts and becomes more wrinkly.
The glands where sperm is produced are called testes or testicles. They are located in the scrotum, a pouch of skin located outside the body that helps regulate the temperature of the testes for sperm production.
Many terrestrial male mammals have external reproductive organs (testicles) to keep their sperm at a lower temperature than the body. Within the testicles the sperm are generated and mature by the process of spermatogenesis.
The best temperature to keep sperm alive is with the human body. You may realise that during very cold temperatures your scrotum tends to go closer to your body. This is because they want to get the body heat. Once the sperm leaves the penis, it will not survive for very long.
Sperm develops best when at normal body temperature. They are very sensitive to temperature changes. Thus, the body does everything it can to help regulate the internal temperature to help protect the reproductive area.
The sperm keeps it temperature because the ball sack will lower when the body temperature is to warm for the sperm. Although if the air is to cold the ball sack will higher closer to the body and warm up the cold sperms.
No, they have to be a couple of degrees below body temperature to produce. That's why the testicles are outside the body so that they can be a little cooler.
Sperm are best produced at a temperature slightly below the temperature of the rest of your body, that is the purpose of having external testicles (rather than inside of your body). To help regulate the temperature of your testes, your body will raise them if they are too cold or lower them some if they get too hot.
The sperm count is dependent on the temperature of the testes. The testes are external to the body because they require a lower temperature to produce viable sperm. The testes work best at temperatures slightly less than core body temperature. Spermatogenesis is less efficient at lower and higher temperatures. This is the reason for retraction of the testes in the cold as well as non-viable sperm in men with (medically) undescended testes.
Normal sperm production occurs at around 94-96 degrees Fahrenheit, which is slightly below normal body temperature. This is why the testicles are located outside the body in the scrotum, as it helps to maintain a cooler temperature for optimal sperm production.
The testicles are outside of the body for temperature control. The sperm develop best when the temperature is lower than the body temperature. If the testicles were kept at body temperature, the sperm would not develop correctly. The body has an ingenious temperature control mechanism, as well, for the testicles. If it is too hot for them, they descend and hang further away from the body. If it is too cold for them, they come up closer to the body!
Iit is naturally produced by your body.
