I did the diagram myself based on the one found on the book "Gray's anatomy" 36th edition, Williams & Warwick, 1980; and a diagram found of the review "Formation and organization of the mammalian sperm head" from Kiyotaka Toshimori and Chizuro Ito.

The sperm cell of Homo sapiens is the small reproductive cell produced by males, and can only survive in warm environments; upon leaving the body, it starts to degrade, thereby decreasing the total sperm quality. Sperm cells normally come in two types, "female" and "male", named for the resulting sex of the fertilized zygote each produces after ...
Diagram of a human sperm cell. Sperm (pl.: sperm or sperms) is the male reproductive cell, or gamete, in anisogamous forms of sexual reproduction (forms in which there is a larger, female reproductive cell and a smaller, male one).
Sertoli cells function to nourish the developing sperm cells. They secrete androgen-binding protein , a binding protein which increases the concentration of testosterone. There are two types: convoluted and straight, convoluted toward the lateral side, and straight as the tubule comes medially to form ducts that will exit the testis.
Diagram of a human spermatozoa showing the acrosome. The acrosome is an organelle that develops over the anterior (front) half of the head in the spermatozoa (sperm cells) of humans and many other animals. It is a cap-like structure derived from the Golgi apparatus.
Spermatogenesis is the process in which sperm cells are produced and formed into mature spermatozoa from spermatogonia. Males mature spermatozoa (sperm) are produced to later join with a female oocyte (egg) to create offspring. Throughout the process of spermatogenesis, there are many different parts of the male anatomy, accessory organs, and ...
The tubules are lined with a layer of cells that develop from puberty through old age into sperm cells (also known as spermatozoa or male gametes). [5] The developing sperm travel through the seminiferous tubules to the rete testis located in the mediastinum testis , to the efferent ducts , and then to the epididymis where newly created sperm ...
