- The video is about the anatomy of the testes/testicles. - The testes are male gonads and are responsible for sperm production and testosterone production. - They are located outside of the body in the scrotum for temperature regulation. - The shape of the testes is important to recognize for detecting abnormalities such as testicular cancer. - The testes are connected to the body through the spermatic cord, which supplies blood, drainage, nerves, and the duct for spermatozoa. - The testicular artery is a branch of the aorta. - The gonads form in the posterior abdominal wall during embryonic development. - Understanding the anatomy of the testes is important for detecting abnormalities and understanding testicular cancer. In this video, the presenter discusses the anatomy of the testes, including their location, function, structure, blood supply, lymphatic drainage, and innovation. The testes are the male gonads responsible for spermatogenesis and the production of testosterone. They are located outside the body in the scrotum for thermoregulation purposes. The presenter notes that understanding the anatomical structure of the testes is important for identifying and diagnosing testicular cancer. The video also covers embryological development and the formation of the testes in the posterior abdominal wall. The presenter emphasizes the importance of recognizing the normal shape of the testes in order to detect any abnormalities or lumps that may indicate testicular cancer.

Just finished my anatomy spotter exam for first year, I don't know how it went but discovering your channel two days ago was the best thing that happened to me - at least now I have some understanding of anatomy!

Very high quality work produced with passion :) You will get famous soon. Love from Pakistan

Thank you so much for your videos they are my main source for studying lab anatomy I am grateful for you hard work and thank you very much

Thank you so much. Some of the benefits you mentioned coincided with the pain our family was going through.

May Allah protect you and your family from all sadness in life. Ameen. Thank you for all you do because your videos actually mean the world to me right now.

@@SamWebster Hi sir . I hope u can notice me . I have a question if its okay . On the other video the spermatic anatomy U mention about the base of epididymis which is where the ductus deferens connect . Sir how doest it feel the base of epididymis connected by the ductus def..does it feel like a round tube or like a small sac /smaller narble..firm/hard but smooth .? Is that the normal of the base epididymis.??

6 months ago I received a blow to the right testicle. Yesterday I noticed that on my right testicle on the left side somewhere in the middle of the testicle I have a knot like a grain of rice caught right from the testicle. I only feel this knot if I press on the testicle, then I feel it stay stronger. Can it be normal? How many appendices does the testicle have? There are 2 epididymals and 1 testicle. I'm only 16 years old. Please help. Can a testicular tumor be as big as a grain of rice? can it be caused by the blow? I don't have any people with cancer or anything, please help me. can I have cancer if I am not exposed to any risk factors?

Did you ever feel your testicles before the blow? Otherwise you have no comparison.

My son 15 months, his right side testicle is moving upward often, what is the reason. Is it dangerous.

Hi vijaya Lakshmi,sorry for the late reply. Is it only the right testicle or both? If both, it happens sometimes due to the change of weather. For example if the environment is cold, the testicle starts to get close to the body or moving upwards to receive heat from the body. If it is a hot environment,then it's started to move downwards or far from the body to release heat to be in a suitable temperature.Fun fact that the testicle and our body does not have the same temperature.

Good idea.

good job

youre too cute & explain well, the perfect professor

The veiod are very helpful for studies✏

Does size of the testes matter - what is the average size? Is there any relation to infertility with smaller testes

The human testicles are a... productive... topic of anatomy.

Well I just learned that I'm unique because my Right testis sits lower than my left one. Lol I didn't know it was common for it to be more one way then the other lol
