This is attached to the testis and extends through the inguinal canal to the wall of the scrotum as a testis. It carries with it the ductus deference, which are testicular vessels and nerves, a portion of the abdominal muscle, and lymph vessels. All of the structures remain attached to the testis and form what is known as the spermatic cord.
The connective tissue of the tunica albuginea testis extends into the substance of the testis to form fibrous partitions - the septa testis. [1] At the posterior aspect of the testis (where the serosa of testis is deficient to allow for the attachment of the epididymis), the tunica albuginea extends into the testis to form the mediastinum ...
Testicular cancer is highly treatable and usually curable. [5] Treatment options may include surgery, radiation therapy, chemotherapy, or stem cell transplantation. [2] Even in cases in which cancer has spread widely, chemotherapy offers a cure rate greater than 80%. [4] Globally testicular cancer affected about 686,000 people in 2015. [6]
A testicle or testis (pl. testes) is the gonad in all male bilaterians, including humans, and is homologous to the ovary in females. Its primary functions are the production of sperm and the secretion of androgens, primarily testosterone. The release of testosterone is regulated by luteinizing hormone (LH) from the anterior pituitary gland.

Testicular cancer is most common in males between the age 20–34 years old, and can appear as soon as the age of 15 years old. It is important to start STE at a young age, to detect any possible signs for testicular cancer. [7] A testicular self-examination can be done in front of a mirror to look at the entire surface.
In men aged 15 to 40, testicular cancer is the most common cancer, [4] [5] and the annual rate of increase over the last 10 years in cases of testicular cancer has been shown to be approximately 1% each year. [6] Testicular cancer typically presents with a painless testicular swelling or lump or any change in shape or texture of the testicles. [7]
Müllerian duct, the upper part of which remains as the hydatid of Morgagni; the lower part, represented by a dotted line descending to the prostatic utricle, constitutes the occasionally existing cornu and tube of the uterus masculinus: ot.
