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.
An androgen (from Greek andr-, the stem of the word meaning ' man ') is any natural or synthetic steroid hormone that regulates the development and maintenance of male characteristics in vertebrates by binding to androgen receptors. [1] [2] This includes the embryological development of the primary male sex organs, and the development of male ...
Leydig cells release a class of hormones called androgens (19-carbon steroids). [8] They secrete testosterone, androstenedione and dehydroepiandrosterone (DHEA), when stimulated by the luteinizing hormone (LH), which is released from the anterior pituitary in response to gonadotropin releasing hormone which in turn is released by the hypothalamus.

He published a description of his eponymous cell in 1865. [2] The cell was discovered by Sertoli with a Belthle microscope which had been purchased in 1862. In the 1865 publication, his first description used the terms "tree-like cell" or "stringy cell"; most importantly, he referred to these as "mother cells".
Testosterone, which is produced by your testicles, “plays a key role in the development of characteristics like libido, and growth of the penis and testicles,” says Jamin Brahmbhatt, MD, a ...
These are produced in the testicles, which are housed in the temperature-regulating scrotum; immature sperm then travel to the epididymides for development and storage. The second category are the ejaculatory fluid producing glands which include the Cowper's gland (also called bulbourethral gland), seminal vesicles , prostate , and vas deferens .
Substance and drug abuse, such as alcohol, opioids, and anabolic-androgenic steroids, can affect testosterone production and interfere with testicular and hypothalamic-pituitary function, research ...
