Male hormone is produced in the testis by cells of

The testes — also called testicles — are two oval-shaped organs in the male reproductive system. They’re contained in a sac of skin called the Structures within the testes are important for the production and storage of sperm until they’re mature enough for ejaculation. The testes also produce a hormone called The main function of the testes is producing and storing sperm. They’re also crucial for creating testosterone and other male hormones called androgens. Testes get their ovular shape from tissues known as lobules. Lobules are made up of coiled tubes surrounded by dense connective tissues. Seminiferous tubules Seminiferous tubules are coiled tubes that make up most of each testis. The cells and tissues in the tubules are responsible for spermatogenesis, which is the process of creating sperm. These tubules are lined with a layer of tissue called the epithelium. This layer is made up of Sertoli cells that aid in the production of hormones that generate sperm. Among the Sertoli cells are spermatogenic cells that divide and become spermatozoa, or sperm cells. The tissues next to the tubules are called Leydig cells. These cells produce male hormones, such as testosterone and other androgens. Rete testis After sperm is created in the seminiferous tubules, sperm cells travel toward the Before sperm can get to the epididymis, they can’t move. Millions of tiny projections in the rete testis, known as microvilli, help move sperm along to the efferent tubules. Efferent ducts Th...

MALE REPRODUCTIVE SYSTEM MALE REPRODUCTIVE SYSTEM The male reproductive system includes two testes, which like the ovaries, have a dual function. They produce the male germ cells (spermatozoa) and the male hormones (androgens). The germ cells differentiate to morphologically mature spermatozoa in the seminiferous tubules within the testis. The spermatozoa leave the testis via the rete testis and enter a tubule system including the epididymis and vas deferens , which travels through the abdominal cavity to join with the urethra which enters the penis. Near the bladder, the vas deferens is joined by the seminal vesicle and the prostate gland, forming the ejaculatory duct. The male hormone, testosterone, is produced by the interstitial or Leydig cells found between seminiferous tubules. Testis The testis is composed of network of highly convoluted tubules, the seminiferous tubules which are lined with spermatogenic cells and supporting cells, the sertoli cells ( spermatocytes. The primary spermatocytes are the largest of the maturing germ cells and divide meiotically to give rise to the secondary spermatocytes. These cells are smaller than the primary spermatocytes and are rarely seen in sections, since they divide again rapidly to form the haploid spermatids. Spermatids do not divide, but undergo a morphological transformation (spermiogenesis) to become spermatozoa or sperm. These cells are found in the center of the tubules ( cells are tall irregularly shaped cells which ab...

The function of the male reproductive system depends on the action of several chemicals and hormones that are produced by different body glands. Some of these hormones are named as tropic hormones due to their ability to launch other hormones. Other hormones of the male reproductive system have a direct relation to body systems and organs while controlling the production of semen and range of emotions. Note that, the male reproductive system does not follow hormone fluctuation cycle per month like females rather these hormones stay consistently active in the body throughout their life. There are five major types of hormones in the male reproductive system; essential details about these fluids are discussed as below. Gonadotrophin-Releasing Hormone This hormone is secreted and produced by specialized nerve cells in the brain hypothalamus. The released fluid flows to pituitary glands through tiny blood vessels and then stimulates two new hormones named as a luteinizing and follicle stimulating hormone. These hormones are further released to complete general circulation in the reproductive system, and they work on testes to manage various functions of the reproductive system. Luteinising and follicle stimulating hormones also control the production of sperm in the male reproductive system. • Facts behind the production of Gonadotrophin-releasing hormone: The Gonadotrophin-releasing hormone levels are quite low in children, but as the person approaches puberty stage, the produ...

Learning Objectives By the end of this section, you will be able to: • Identify the most important hormones produced by the testes and ovaries • Name the hormones produced by the placenta and state their functions This section briefly discusses the hormonal role of the gonads—the male testes and female ovaries—which produce the sex cells (sperm and ova) and secrete the gonadal hormones. The roles of the gonadotropins released from the anterior pituitary (FSH and LH) were discussed earlier. The primary hormone produced by the male testes is testosterone, a steroid hormone important in the development of the male reproductive system, the maturation of sperm cells, and the development of male secondary sex characteristics such as a deepened voice, body hair, and increased muscle mass. Interestingly, testosterone is also produced in the female ovaries, but at a much reduced level. In addition, the testes produce the peptide hormone inhibin, which inhibits the secretion of FSH from the anterior pituitary gland. FSH stimulates spermatogenesis. The primary hormones produced by the ovaries are estrogens, which include estradiol, estriol, and estrone. Estrogens play an important role in a larger number of physiological processes, including the development of the female reproductive system, regulation of the menstrual cycle, the development of female secondary sex characteristics such as increased adipose tissue and the development of breast tissue, and the maintenance of pregnancy....
