- In the male, the principal sex hormones are the androgens, of which testosterone is the most important. The androgens are steroid hormones produced mainly by the Leydig cells(interstitial cells located near the seminiferous tubules) of the Testes.

Human Physiology/The male reproductive system In between the seminiferous tubules within the testes, are instititial cells, or, Cells of Leydig. They are responsible for secreting the male sex hormones (i.e., testosterone). Sertoli Cells. A Sertoli cell (a kind of sustentacular cell) is a 'nurse' cell of the testes which is part of a seminiferous tubule.he seminiferous tubules join together to become the epididymis. The epididymis is a tube that is about 2 inches that is coiled on the posterior surface of each testis. Within the epididymis the sperm complete their maturation and their flagella become functional.

RIXIMKA DUMARKA The primary functions of the testes are to produce sperm (spermatogenesis) and to produce androgens, primarily testosterone. Both functions of the testicle are influenced by gonadotropic hormones produced by the anterior pituitary. Luteinizing hormone (LH) results in testosterone release.The presence of both testosterone and follicle-stimulating hormone (FSH) is needed to support spermatogenesis.oth functions of the testicle are influenced by gonadotropic hormones produced by the anterior pituitary.

Spermatogenesis The seminiferous tubules of the testes are the starting point for the process, where stem cells adjacent to the inner tubule wall divide in a centripetal direction—beginning at the walls and proceeding into the innermost part, or lumen —to produce immature sperm. Maturation occurs in the epididymis.permatogenesis takes place within several structures of the male reproductive system. The initial stages occur within the testes and progress to the epididymis where the developing gametes mature and are stored until ejaculation.

- The entire male reproductive system is dependent on hormones, which are chemicals that regulate the activity of many different types of cells or organs. The primary hormones involved in the male reproductive system are follicle-stimulating hormone, luteinizing hormone, and testosterone.Follicle-stimulating hormone is necessary for sperm production (spermatogenesis), and luteinizing hormone stimulates the production of testosterone, which is also needed to make sperm.he primary hormones involved in the male reproductive system are follicle-stimulating hormone, luteinizing hormone, and testosterone.

THE REPRODUCTIVE SYSTEM Seminiferous tubules are inside each testis, and are where sperm are produced by meiosis. About 250 meters (850 feet) of tubules are packed into each testis. Spermatocytes inside the tubules divide by meiosis to produce spermatids that in turn develop into mature sperm. The male reproductive system.

- In males, the gonads are the testes. Their corresponding hormones  include:   Testosterone-This stimulates spermatogenesis, growth, and  maturation of sperm as well as the production of secondary sex  characteristics.  Inhibin-This hormone inhibits the secretion of follicle  stimulating hormone.     In males, the gonads are the testes. Their corresponding hormones  include:   Testosterone-This stimulates spermatogenesis, growth, and  maturation of sperm as well as the production of secondary sex  characteristics.

Spermatogenesis INTERSTITIAL CELLS (also known as Leydig cells) in the testes surround the seminiferous tubules and produce the male hormone TESTOSTERONE. SPERM – the male gamete • Men can produce up to 1,000,000,000 sperm per day. The whole process of spermatogenesis takes about 9 or 10 weeks.

Reproductive system The male reproductive system. The main tasks of the male reproductive system are to produce sperm cells and to introduce sperm into the female reproductive tract. Sperm are produced in the testes, the pair of male reproductive glands located in the scrotum, a skin-covered sac that hangs from the groin. Within each testis are hollow tubules called seminiferous tubules where sperm cells are produced.

Fertility Education & Training The oestrogen also stimulates the glands in the cervix to disperse the mesh mucus and produce instead a wet slippery mucus with swimming lanes along which sperm can move easily, as if on a “motorway”. This new mucus is alkaline and contains glucose and other nutrients vital to sperm survival.

- Chapter 28 Reproductive System The goal of the reproductive system is to produce a new, unique organism. But first, some terminology! o Primary sex organs = gonads. They produce hormones and sex cells called gametes. The gametes are sperm and ovum. o Accessory sex organs = ducts, glands and external genitalia.he seminiferous tubules There are a few different types of cells in the seminiferous tubues: 1. Developing sperm cells 2. Sertoli cells 3. Leydig cell (interstitial cells that produce testosterone) Glands The bulk of semen comes from vesicular fluid (2/3) and the prostatic fluid (1/3).

Anatomy of the Testes Seminiferous tubules lie within the testes and are separated by partitions, which are extensions of the tunica albuginea, the middle layers of the testes’ covering. They house germ cells (23 chromosome cells which in men replicate to produce sperm) and are the site of spermatogenesis (sperm production).

Sperm Production (Spermatogenesis), Parts, Quantity and Motility The production of sperm is a multi-step process that occurs within the seminiferous tubules which are long hollow coiled tubes in the testes. There are close to 1,000 such tubules measuring some one and a half meters in each testis.

Spermatogenesis From Wikipedia, the free encyclopedia. Spermatogenesis is the process in which spermatozoa are produced from male primordial germ cells by way of mitosis and meiosis. The initial cells in this pathway are called spermatogonia, which yield primary spermatocytes by mitosis.he mature spermatozoa are released from the protective Sertoli cells into the lumen of the seminiferous tubule in a process called spermiation. The non-motile spermatozoa are transported to the epididymis in testicular fluid secreted by the Sertoli cells with the aid of peristaltic contraction.

Test Bank Of Essentials of Anatomy And Physiology 7th Edition by Martini Bartholomew The fructose portion of this fluid provides nourishment for the highly active spermatozoa. This fluid, produced by both seminal vesicles, accounts for over 50% of the total volume of seminal fluid. The remainder is contributed by the prostate gland, with a small contribution from the bulbourethral glands.
