The Male Reproductive System

The organs of the courageous reproductive regularity are especialized for the forthcoming exercises: To yield, conceal and ecstasy sperm (the courageous reproductive cells) and protective melting (semen) To emptiness sperm among the fecourageous reproductive believe To yield and hide courageous sex hormones The courageous reproductive analysis grasps interior and manifest constitutions. What are the manifest reproductive constitutions? Most of the courageous reproductive regularity is located delayout of the man’s substantiality. The manifest constitutions of the courageous reproductive regularity are the penis, the scrotum and the testicles. PenisThe penis is the courageous organ for sexual dealing. It has three parts: the fountain, which fixes to the respect of the abdomen; the substantiality, or shaft; and the glans, which is the cone-shaped end of the penis. The glans, which besides is determined the gathering of the penis, is balmy delay a unbound lamina of husk determined foreskin. (This husk is rarely removed in a arrangement determined circumcision. ) The space of the urethra, the tube that ecstasys semen and urine, is at the tip of the glans penis. The penis besides contains a enumerate of perceptive firmness endings. The substantiality of the penis is cylindrical in fashion and consists of three interior chambers.These chambers are made up of especial, sponge-like plantile work. This work contains thousands of great spaces that stuff delay rank when the man is sexually aroused. As the penis stuffs delay rank, it becomes tough and plant, which remits for acuteness during sexual dealing. The husk of the penis is unbound and resilient to accommodate changes in penis magnitude during an plantion. Semen, which contains sperm, is expelled (ejaculated) through the end of the penis when the man reaches sexual culmination (orgasm). When the penis is plant, the course of urine is blocked from the urethra, remiting barely semen to be jaculated at orgasm. Scrotum The scrotum is the unbound pouch-like sac of husk that hangs following the penis. It contains the testicles (besides determined testes), as polite-mannered-mannered as multifarious firmnesss and rank vessels. The scrotum has a protective exercise and acts as a air rale regularity for the testes. For natural sperm crop, the testes must be at a weather subordinately promisinger than the substantiality weather. Especial muscles in the respect of the scrotum remit it to conbelieve and loosen, affecting the testicles closer to the substantiality for ardor and shelter or farther abroad from the substantiality to promising the weather. Testicles (testes)The testes are oval organs encircling the magnitude of great olives that lie in the scrotum, impregneffectual at either end by a constitution determined the spermatic continuity. Most men accept two testes. The testes are imperative for making testosterone, the relevant courageous sex hormone, and for generating sperm. Among the testes are serpentine magnitudees of tubes determined seminiferous tubules. These tubules are imperative for conceding the sperm cells through a arrangement determined spermatogenesis. Epididymis The epididymis is a desire, serpentine tube that rests on the backside of each testicle. It exercises in the ecstasy and storage of the sperm cells that are yieldd in the testes.It besides is the job of the epididymis to product the sperm to manliness, since the sperm that appear from the testes are crude and incompetent of fertilization. During sexual arousal, formions validity the sperm into the vas deferens. What are the interior reproductive organs? The interior organs of the courageous reproductive regularity, besides determined friend organs, grasp the forthcoming: Vas deferens — The vas deferens is a desire, brawny tube that travels from the epididymis into the pelvic planeness, to exact following the bladder. The vas deferens ecstasys aged sperm to the urethra in provision for cry.Ejaculatory ducts — These are formed by the diffuse of the vas deferens and the seminal vesicles. The ejaculatory ducts emptiness into the urethra. Urethra — The urethra is the tube that carries urine from the bladder to delayout of the substantiality. In courageouss, it has the fixed exercise of expelling (ejaculating) semen when the man reaches orgasm. When the penis is plant during sex, the course of urine is blocked from the urethra, remiting barely semen to be castd at orgasm. Seminal vesicles — The seminal vesicles are sac-like pouches that fix to the vas deferens adjacent the disesteemed of the bladder.The seminal vesicles yield a sugar-rich melting (fructose) that provides sperm delay a fountain of disembodiment and succors delay the sperms’ motility (force to advance). The melting of the seminal vesicles performs up most of the size of a man’s ejaculatory melting, or cast. Prostate gland — The prostate gland is a walnut-sized constitution that is located beneath the urinary bladder in face of the rectum. The prostate gland contributes fixed melting to the cast. Prostate meltings besides succor to promote the sperm. The urethra, which carries the cast to be expelled during orgasm, runs through the benevolence of the prostate gland.Bulbourethral glands — The bulbourethral glands, or Cowper’s glands, are pea-sized constitutions located on the sides of the urethra exact beneath the prostate gland. These glands yield a bright, unprincipled melting that empties undeviatingly into the urethra. This melting serves to glaze the urethra and to counterbalance any acidity that may be bestow due to residual drops of urine in the urethra. How does the courageous reproductive regularity exercise? The solid courageous reproductive regularity is relative on hormones, which are chemicals that embitter or rale the motive of cells or organs. The relevant hormones concerned in the exerciseing of the courageous reproductive regularity are follicle-stimulating hormone (FSH), luteinizing hormone (LH) and testosterone. FSH and LH are yieldd by the pituitary gland located at the disesteemed of the brain. FSH is requisite for sperm genesis (spermatogenesis), and LH embitters the genesis of testosterone, which is requisite to continue the arrangement of spermatogenesis. Testosterone besides is relevant in the crop of courageous characteristics, including muscle magnitude and force, fat distribution, bone magnitude and sex force. Does a man go through menopause?Menopause is a voceffectual used to recount the end of a woman's natural menstrual exercise. Fecourageous menopause is characterized by changes in hormone genesis. The testes, unequally the ovaries, do not waste the force to perform hormones. If a man is healthful, he may be effectual to perform sperm polite-mannered-mannered into his 80s or desireer. On the other agency, jesuitical changes in the exercise of the testes may happen as forthcoming as 45 to 50 years of age, and past dramatically behind the age of 70. For multifarious men, hormone genesis may continue natural into old age, occasion others may accept frugal hormone genesis antecedent on, rarely as a issue of an illness, such as diabetes.Whether consumption testicular exercise contributes to such symptoms as tire, want, dejection or incapacity frequently continues doubtful. Can "courageous menopause" be treated? If testosterone levels are low, hormone retrieval therapy may succor help symptoms, such as the waste of cause in sex, dejection and tire. However, replacing courageous hormones can worsen prostate cancer and, peradventure, atherosclerosis (hardening of the arteries). A man should assent-to a entire substantial evidence and laboratory tests should be done starting hormone retrieval therapy. How multifarious middle-aged men succeed favor from such therapy continues an public inquiry.
