The testicles are very sensitive to impact and injury. The pain involved travels up from each testicle into the abdominal cavity, via the spermatic plexus, which is the primary nerve of each testicle. [31] This will cause pain in the hip and the back. The pain usually fades within a few minutes. Testicular torsion is a medical emergency. This ...

Diagrams that show the development of male and female organs from a common precursor. Sperm ducts and fallopian tubes are not homologous, as the sperm ducts originate from the Wolffian ducts, whereas the fallopian tubes originate from the Müllerian ducts. Homologous structures in the external genitalia

Diagram of the scrotum. On the left side, the cavity of the tunica vaginalis has been opened; on the right side, only the layers superficial to the cremaster muscle have been removed. In regards to humans, the scrotum is a suspended dual-chambered sac of skin and muscular tissue containing the testicles and the lower part of the spermatic cords.

The tunica albuginea is a dense, [1] [2] blue-white [3] layer of fibrous tissue surrounding the testis. [1] [4] It is the middle of three envelopes forming the capsule of the testis; it is deep to the visceral layer of tunica vaginalis, and superficial to the tunica vasculosa testis (vascular layer of testis).
The tubuli seminiferi recti (also known as the tubuli recti, tubulus rectus, or straight seminiferous tubules) are structures in the testicle connecting the convoluted region of the seminiferous tubules to the rete testis, although the tubuli recti have a different appearance distinguishing them from these two structures.
